Der deutsche Hersteller von Leistungsoptimierern, BRC Solar, und der Wechselrichterhersteller Sungrow erweitern ihre Zusammenarbeit. Die neue Optimierergeneration M605-M wurde für den Einsatz mit den Sungrow SHT-Hybridwechselrichtern freigegeben.
Mit der Freigabe steht Installateuren und Planern eine weitere Option für die Umsetzung von Photovoltaikprojekten mit Leistungsoptimierung zur Verfügung.
Die Freigabe bestätigt die technische Kompatibilität zwischen den Leistungsoptimierern der M605-M-Serie und den Wechselrichtern der Sungrow SHT-Serie. Damit können Fachpartner die Komponenten in einer abgestimmten Systemkombination einsetzen. Die Freigabe ermöglicht zudem die Nutzung der bestehenden Herstellergarantien entsprechend den jeweiligen Garantiebedingungen.
Mit der M605-M-Serie erweitert BRC Solar sein Portfolio um eine weitere Lösung für die Moduloptimierung. Die Plattform unterstützt ein erweiterbares Monitoring – von der Überwachung einzelner Optimierer bis hin zu Photovoltaikanlagen mit mehreren BRConnect Gateways. Voll- und Teiloptimierung können unabhängig vom eingesetzten Wechselrichter umgesetzt werden. Die für BRC Solar Optimierer geltende 25-jährige Produktgarantie ab Installationsdatum bietet dabei eine langfristige Absicherung der Produkte.
Herausfordernde Installationsbedingungen gehören zum Photovoltaik-Alltag. Leistungseinbußen einzelner Module können sich auf den Ertrag eines Strings auswirken. Leistungsoptimierer ermöglichen es, betroffene Module unabhängig zu betreiben und die Auswirkungen von Leistungsunterschieden innerhalb des Systems zu begrenzen.
In Kombination mit den Wechselrichtern der Sungrow SHT-Serie steht damit eine geprüfte Systemkombination für unterschiedliche Anwendungsfälle zur Verfügung. Die Zusammenarbeit beider Unternehmen umfasst die technische Abstimmung der Komponenten und schafft zusätzliche Optionen für die Planung von Photovoltaikanlagen.

Wir freuen uns auf die weitere Zusammenarbeit mit BRC.“
Mit der Freigabe der M605-M-Serie für die Sungrow SHT-Serie setzen Sungrow und BRC Solar ihre technische Zusammenarbeit fort und erweitern die verfügbaren Optionen für Photovoltaikanlagen mit Leistungsoptimierung.
Warum die Zimmerdecke bei der Suche nach effizienten Heiz- und Kühllösungen zunehmend in den Fokus rückt und welche Vorteile sie bietet.
Wenn es um die Beheizung von Räumen geht, sind Heizkörper und Fußbodenheizungen die bekanntesten Lösungen. Eine Fläche wird dabei häufig übersehen: die Decke. Dabei bietet sie ideale Voraussetzungen für eine großflächige Wärmeübertragung und kann zugleich für die Kühlung eingesetzt werden.
Die Klima-Top, Partner der Raum-K, macht sich dieses Prinzip seit mehreren Jahrzehnten mit ihren Klimadecken zunutze. Die Wärme wird dabei überwiegend als Strahlungswärme an den Raum abgegeben. Im Unterschied zur klassischen Konvektionsheizung wird die Wärme nicht in erster Linie über die Erwärmung und Bewegung der Raumluft verteilt. Stattdessen werden die Oberflächen im Raum direkt erwärmt. Die physikalische Grundlage ist der Strahlungsaustausch zwischen unterschiedlich temperierten Oberflächen.
Wärme dort, wo sie gebraucht wird
Der Leiter des technischen Büros, Erwin Aurbacher, hat als staatlich geprüfter Bautechniker, BNK-Auditor, Energieberater und Energieberater Baudenkmale viele Neubauten und Sanierungsprojekte energetisch betreut. Zur Heizung an der Decke erklärt er: „Eine vollflächig aktivierte Klimadecke arbeitet mit einem Strahlungsanteil von bis zu 97 %. Die Luftbewegung im Raum bleibt dagegen gering, ebenso die Staubbelastung. Das führt zu einem gleichmäßigen Wärmeempfinden und reduziert zugleich die für konvektive Heizsysteme typische Luftzirkulation.“ Der Ansatz unterscheidet sich damit grundlegend von einer Heizung, die vor allem die Raumluft erwärmt. Bei einer Klimadecke werden die Oberflächen im Raum stärker in den Wärmehaushalt einbezogen. Das erzeugt ein angenehmes Raumklima bei niedrigen Lufttemperaturen.
Niedrige Vorlauftemperatur – ideal für Wärmepumpen
Für die Effizienz von Wärmepumpen spielt eine niedrige Vorlauftemperatur eine wichtige Rolle. Je geringer diese ist, desto effizienter arbeiten Wärmepumpen. Eine große Heizfläche an der Decke bietet aber nicht nur gute Voraussetzungen für den Betrieb mit Wärmepumpen, sie kann naturgemäß auch die ganze Fläche nutzen. Anders als der Fußboden ist eine Heizfläche an der Decke nämlich nicht durch Einrichtungsgegenstände wie Möbel und Teppiche abgedeckt. Die große, freie Deckenfläche garantiert eine ungehinderte und gleichmäßige Wärmeübertragung.
Heizen und Kühlen mit einem System
Die Raum-K-Klimadecken können aber nicht nur heizen. Im Sommer lässt sich das Prinzip umkehren, sodass die erwärmten Oberflächen im Raum ihre Wärmestrahlung an die kühlere Decke abgeben. Das Kühlwasser führt die aufgenommene Wärme ab. Die Kühlung erfolgt unsichtbar, energieeffizient und ohne den permanenten kalten Luftstrom klassischer Klimageräte. Die Decke wird damit zu einer großflächigen Komfortfläche für alle Jahreszeiten.
Ein weiterer Vorteil der Raum-K-Klimadecken liegt in der unkomplizierten Nutzung der Fläche. Klassische, an der Wand montierte Radiatoren reduzieren Nutzfläche im Raum. Eine Fußbodenheizung bestimmt nicht unerheblich die Wahl von Bodenbelägen und muss auch bei der Möblierung berücksichtigt werden. Die Decke dagegen ist in der Regel frei von störenden Elementen. Meist ist an der Decke lediglich die Deckenbeleuchtung zu berücksichtigen, und das ist in der Regel ein einziges Kabel. Klimadecken erleichtern aber nicht nur die Raumgestaltung, auch die Montage kann in der Regel im bewohnten Zustand eines Objektes Raum für Raum erfolgen. Die Heiztechnik kann dabei mit einer minimalen Aufbauhöhe von nur drei Zentimetern installiert werden – zwei Zentimeter für das Heizprofil und ein Zentimeter für die Gipsplatte. Ein Abhängen der Klimadecken ist immer möglich, was vor allem im Gewerbebau wichtig ist. Sollen in einem Altbau die schönen hohen Räume erhalten bleiben, ist der Minimal-Aufbau mit drei Zentimetern die richtige Wahl. Die gesamte Heiztechnik verschwindet nach der Montage unsichtbar in der Decke des Raumes.
Bewährt in Neubau und Sanierung
Dass sich das Prinzip in der Praxis bewährt, zeigen die folgenden Beispiele. So ermöglichen Raum-K-Klimadecken im Neubau der Wirtschaftsuniversität Wien energieeffizientes Heizen und Kühlen. Im denkmalgeschützten Wasserturm Stromeyersdorf in Konstanzhaben Klimadecken eine energetische Modernisierung ermöglicht, obwohl die historische Fassade nach Denkmalschutzvorgabe nicht gedämmt werden durfte und der Eigentümer auf eine Innendämmung verzichten wollte, um die besondere Raumwirkung zu erhalten. Im Schloss Wertingen, dessen Ursprünge bis ins 14. Jahrhundert zurückreichen, kamen die Klimadecken im Zuge einer umfassenden Sanierung zum Einsatz. Sie ersetzten die frühere Elektro-Speicherheizung und tragen gemeinsam mit Wärmepumpen und niedrigen Vorlauftemperaturen dazu bei, den Energiebedarf zu senken. Zu guter Letzt zeigt das neue Firmengebäude der Raum-K GmbH in Memmingen, was mit Klimadecken, Gebäudemassespeicher, Photovoltaik auf Dach und Fassade, Solewärmepumpe und Elektromobilität mit einem modernen Gebäudeenergiekonzept an Wirtschaftlichkeit möglich ist.
Decke neu denken
Mit der Raum-K-Klimadecke wird die Zimmerdecke zur aktiven Komfortfläche. Sie kann heizen, kühlen, speichern und ermöglicht durch niedrige Vorlauftemperaturen energiesparenden Betrieb. Die Überlegung bei der Planung einer neuen Heizung sollte deshalb nicht lauten: „Wo kommen die Heizkörper hin?“ Die Überlegung sollte lauten: „Lassen Sie uns einfach an die Decke gehen.“
Wiedervernässung und Photovoltaik müssen kein Widerspruch sein. Eine neue Fraunhofer-Handreichung zeigt, was Moor-PV leisten kann – und welche Anforderungen die Umsetzung stellt. ProfiNRG entwickelt seit Jahren PV-Projekte auf anspruchsvollen, wassergeprägten Standorten und erklärt worauf es ankommt.
Das Fraunhofer-Institut für Solare Energiesysteme ISE hat gemeinsam mit dem Greifswald Moor Centrum, der Humboldt-Universität zu Berlin, der Universität Göttingen und BBH eine neue Handreichung zu Photovoltaik auf wiedervernässten Moorböden veröffentlicht.
Moor-PV als Baustein für den Klimaschutz
Die Handreichung zeigt, wie Moor-PV zur Verbindung von Wiedervernässung, Klimaschutz und dem Ausbau erneuerbarer Energien beitragen kann. Laut dem Fraunhofer ISE wurden rund 70 % der ehemals intakten Moore in Deutschland für die landwirtschaftliche Nutzung entwässert. Die dadurch geschädigten Moorböden verursachen heute knapp 7 % der deutschen Treibhausgasemissionen, erklärt das Institut.
Die Wiedervernässung trockengelegter Moorflächen in Deutschland soll laut der deutschen Bundesregierung deutlich beschleunigt werden. Moor-PV soll hierbei eine zusätzliche Perspektive eröffnen. Werden die Flächen wieder vernässt, kann mit Moor-PV erneuerbarer Strom erzeugt und eine neue Einnahmequelle für Landwirtschaft und Flächeneigentümer geschaffen werden.
Besondere Anforderungen an Planung und Umsetzung
Moor-PV ist jedoch keine Standard-Freiflächenanlage auf einem beliebigen Untergrund. Die Planung und Umsetzung auf nassen, weichen und unter Umständen schwer zugänglichen Böden stellt besondere Anforderungen an die Standortanalyse, Konstruktion, Baustellenlogistik, Bauausführung und den langfristigen Betrieb. Diese praktischen Fragen entscheiden darüber, wie gut ein Projekt auf lange Sicht funktioniert.
Erfahrung aus Projekten auf anspruchsvollen Standorten
Der Business-Development-Manager des niederländischen EPC-Unternehmens ProfiNRG Christian Steinberg erklärt zu Moor-PV: „Bei ProfiNRG beschäftigen wir uns seit Jahren mit der Errichtung von PV-Freiflächenprojekten in Deutschland und den Niederlanden – auch auf anspruchsvollen, sumpfigen und stark wasserführenden Böden. Unsere Erfahrung zeigt, dass die technischen Herausforderungen lösbar sind. Entscheidend ist jedoch, dass die besonderen Bedingungen des Standorts von Anfang an in die Projektentwicklung integriert werden.“
Worauf es bei Moor-PV ankommt
Dazu gehören laut dem Experten unter anderem:
Eine realistische Bewertung des Boden- und Wasserhaushalts auf der Fläche.
Ein individuelles, speziell für den Standort zugeschnittenes technisches Konzept.
Die sorgfältige Planung und Durchführung von Bau und Logistik.
Eine enge Zusammenarbeit mit Eigentümern, Landwirtschaft, Behörden und Naturschutz.
Ein langfristiger Blick auf Betrieb, Wartung und Rückbau.
Christian Steinbergs Fazit lautet daher: „Die Energiewende braucht nicht einfach mehr PV-Flächen. Sie braucht vor allem intelligente Lösungen für komplexe, anspruchsvolle Standorte, wie z. B. wiederbelebte Moorflächen. Moor-PV kann eine gute Lösung sein, wenn Klimaschutz, Wasserhaushalt, Naturschutz, technische Machbarkeit und die Wirtschaftlichkeit von Anfang an gemeinsam betrachtet werden. Bei ProfiNRG bringen wir dafür unsere jahrelange Erfahrung aus der Entwicklung von PV-Projekten auf herausfordernden Böden in Deutschland und den Niederlanden ein.“

Sauberer Solarstrom und landwirtschaftliche Nutzung auf derselben Fläche – der Agri-PV-Solarpark in Bremen zeigt, wie Photovoltaik und Landwirtschaft erfolgreich zusammenarbeiten. Entwickelt wurde das Projekt vom niederländischen Projektentwickler ProfiNRG.
Realisiert hat ProfiNRG einen Agri-PV-Solarpark mit 23.982 Modulen, 31 Wechselrichtern und einer Gesamtleistung von 14,52 MWp. Die Anlage ermöglicht die gleichzeitige Nutzung der Fläche für die Solarstromerzeugung und die landwirtschaftliche Bewirtschaftung.
Herausforderungen und Lösungen
Die Umsetzung des Solarparks war aufgrund besonderer Standortbedingungen anspruchsvoll. Der hohe Grundwasserspiegel sowie Frost führten zu Verzögerungen bei der Verlegung der AC- und DC-Kabel. Durch gute Abstimmung und professionelle Zusammenarbeit zwischen Projektteam und Partnerunternehmen konnten das Projekt trotz der besonderen Herausforderungen innerhalb des vorgegebenen Zeitfensters erfolgreich abgeschlossen werden.
Der Agri-PV-Solarpark in Bremen ist seit August 2025 in Betrieb und erzeugt zuverlässig erneuerbaren Strom.
Das Projekt ist ein gelungenes Praxis-Beispiel für doppelte Wertschöpfung auf landwirtschaftlicher Fläche und unterstützt außerdem die Weiterentwicklung von Agri-PV-Anwendungen in Europa.
Besonderheiten des Projekts
Der Solarpark verwendet ein Monopile-System, mit einer zentralen Mittelstütze pro Modultisch. Im Vergleich zu Konstruktionen mit vorderen und hinteren Stützen reduziert sich dadurch die Anzahl der erforderlichen Stützen im Erdreich deutlich.
Die größeren Abstände zwischen den Modulreihen sowie die reduzierte Anzahl an Pfosten ermöglichen eine einfache Bewirtschaftung der Fläche. Der Verzicht auf bewegliche Teile, wie sie beispielsweise bei Tracker-Systemen eingesetzt werden, macht die Konstruktion robust, wartungsarm und langlebig.
Zahlen, Daten Fakten:
Leistung: 14,52 MWp
Solarmodule: 23.982 Stück
Wechselrichter: 31 Einheiten mit jeweils 330 kVA
Transformatoren: zwei Einheiten mit 6,6 MVA und 3,3 MVA
Montagesystem: Ein zentraler Pfosten pro Modulreihe. Die Konstruktion ermöglicht größere Reihenabstände und unterstützt die landwirtschaftliche Nutzung der Fläche.
160.48 MWh Speicherprojekt in Rumänien erreicht Installationsphase und markiert den ersten europäischen Einsatz der Elementa–Electra-Architektur.
Im April 2026 hatte Trina Storage die Hardware für das Batterie-Energiespeichersystem (BESS) zum Standort im rund 100 km nördlich von Bukarest gelegenen Izvoarele geliefert.
Das 40 MW/160.48 MWh Speichersystem wurde für netzdienliche Leistungen ausgelegt und basiert auf einer Kombination aus DC–AC-Architektur der Baureihe „Elementa + Electra“. Es nutzt flüssigkeitsgekühlte Speichertechnik und ist im Kern aus 314 Ah-Zellen aufgebaut. Die Besonderheit der Electra-Architektur liegt in der Kombination von Batteriesystem, Leistungswandlung und Mittelspannungstransformation.
Für die Anlage in Izvoarele wurden 32 Einheiten des Batteriespeichersystems Elementa 2 Pro und vier Electra-AC-Einheiten geliefert. Laut Hersteller soll die Systemarchitektur eine abgestimmte Balance von Kapazität und Leistung zwischen Gleich- und Wechselstromseite sowie einen optimierten Netzanschluss ermöglichen.
Da das Projekt für netzdienliche Anwendungen wie Ausgleichsdienste, Arbitragehandel und Lastmanagement ausgelegt ist, wirkt die Architektur vielversprechend. Ob das Zusammenspiel von Speicher- und AC-Technik die Erwartungen erfüllt, wird sich zeigen, wenn die Anlage Ende des dritten Quartals 2026 ans rumänische Netz geht.
35 interviews examine photovoltaic markets, storage deployment and grid development across Central and Eastern Europe between September 2024 and April 2026.
The interviews feature executives, researchers and industry decision-makers from across the region. They highlight differing market conditions, regulatory frameworks and investment dynamics in individual countries, reflecting the growing strategic importance of photovoltaics and energy storage in Central and Eastern Europe.
Dynamic growth and shifting regulatory frameworks are shaping solar markets in Central and Eastern Europe. Jonas Kasal, Managing Director at Memodo, explains how these trends influence strategy, investment and project development.
Munich, 16 April 2026
Can you briefly describe your role, tasks and responsibilities within the company?
I am one of the two Managing Directors of Memodo s.r.o., a company operating across the Czech Republic, Poland, and Slovakia. Given my technical background, I am primarily responsible for defining and driving the company’s product, commercial, and technical support strategy. In the past, I was personally responsible for most C&I (Commercial & Industrial) projects within the company.
How important is C&I for Memodo in the CEE market?
As the market has increasingly shifted toward this segment, we put a strong focus on the C&I business. Today, all our sales representatives have the required skills to design and manage commercial projects.
How has the growing demand in the C&I market reshaped our business strategy?
We follow a holistic approach and place strong emphasis on long-term service and comprehensive support. We therefore offer service contracts alongside our projects to ensure high quality standards. Currently, this is primarily available in the Czech Republic and Slovakia, with plans to extend the offering to Poland.
Since when has Memodo been active in Central and Eastern Europe?
Memodo has been active in the CEE region since early 2018.
In which countries is Memodo active, and what is its presence there?
We have dedicated sales teams in the Czech Republic, Slovakia, and Poland, supported by local-language technical support in each market. From a logistics perspective, we operate from our central warehouse in Prague, which serves all three countries.
What do you consider to be the greatest advantages of the markets in CEE?
The greatest advantage of the CEE markets is their strong growth potential and openness to innovation. These markets are still in a relatively dynamic phase of energy transition, which creates significant opportunities for new technologies, business models, and partnerships.
Is energy security a factor for your customers?
Another key advantage is the increasing awareness of energy security and independence, which is driving demand for decentralized renewable solutions such as solar and battery storage. This provides a favourable environment for companies like Memodo that focus on high-quality, long-term energy solutions rather than purely short-term transactions.
What feedback are you receiving regarding skilled workers?
The CEE region also benefits from a skilled technical workforce and a growing community of installers, engineers and energy professionals who are adopting new technologies and contributing to the modernisation of the energy sector. While the markets can be volatile, their momentum and development potential make them attractive for companies committed to advancing renewable energy.
What do you consider to be the greatest challenges in CEE?
The main challenge in the CEE region is market stability and regulatory predictability. On a yearly basis, support schemes, legislation and market frameworks change. While the transition from centralised to decentralised power generation is necessary and progressing, it also creates uncertainty.
In your opinion, a more regulated environment would help PV development in CEE?
I believe governments should adopt and drive a more long-term strategic perspective. Businesses need stable conditions to invest in sustainable high-quality solutions and aftersales services. Frequent regulatory changes lead to high fluctuation among market participants, which ultimately harms the entire industry — particularly in terms of solution quality and service reliability. As a wholesaler, we ultimately do our best to ensure stability when it comes to our selected suppliers and warranties. However, we cannot replace installers who leave the market or go bankrupt when it comes to end-customer service.
How do you view the markets in CEE in relation to other markets?
CEE markets are significantly more dynamic — but also more volatile — compared to more mature markets such as Germany. They are also highly price-driven.
What would you like to see happen in your markets?
A more stable market would naturally lead to higher overall quality in the market. When businesses operate in a highly dynamic market with subsidy windows that open and close unpredictably, they tend to prioritize the lowest-cost solutions in order to maximize profitability. While I understand this — in many cases it is simply a matter of survival — it is not ideal for the long-term development of the sector. I hope that policymakers recognize this dynamic and work toward more stable, predictable frameworks.
What developments do you expect in CEE over the next two to ten years – say until 2035?
Cybersecurity will become a critical issue and will require clear regulatory frameworks and industry standards. here will also be significant developments in grid services legislation. The market will require greater standardisation, which will be challenging for regulators and grid operators. As coal plants are phased out, renewable energy, particularly solar, will play a larger role in the energy mix. However, many grids are already operating at capacity limits. In this context, battery storage will be essential for grid stabilisation and flexibility services. I also hope there will be broader recognition that renewable energy is not only about reducing CO₂ emissions – it is fundamentally a strategic decision to become more energy indepent.
Tomáš Bílek, responsible for international business development and sales at Fenecon, discusses opportunities and challenges in the region’s growing energy storage market.
Munich, 26. März 2026
Mr Bílek, could you briefly describe your role at Fenecon?
I am responsible for International Business Development and International Sales at Fenecon. Following the company’s internal restructuring, my focus is on the residential and commercial sectors, and until last year also on industrial-scale solutions.
So you are personally responsible for global business development?
Not quite. Our company has divided responsibilities not only functionally but also geographically. The DACH region is managed by our German partner management team. The USA also falls outside my area of responsibility, as we have a separate company there with its own production facilities.
So you’re personally responsible for global business development?
Not quite. Our company has divided responsibilities not only functionally but also geographically. The DACH region is managed by our German partner management team. The USA also falls outside my area of responsibility, as we have a separate company there with its own production facilities.
What is your region?
My focus is primarily on Central and Eastern Europe — from Poland eastwards to Ukraine and further south to North Macedonia and northern Greece, extending even to Georgia.
How is Fenecon approaching internationalization?
We are present throughout Europe primarily through individual projects. Our organized international expansion only began in 2022 due to rapid company growth. Due to internal restructuring, internationalization is still relatively new for us.
In which countries are you currently present?
Currently, we have a structured market presence through country partners in Sweden, the Netherlands, the Czech Republic, Lithuania, Cyprus and Greece. In other countries, such as Croatia and Slovakia, we have established individual contacts and representatives.
What role do the country partners play in the Fenecon universe?
Our approach is not based solely on sales. We work with country partners who essentially act as local Fenecon branches. In addition to sales, they also handle technical support, monitor compliance with regulatory requirements, and provide customer service. It is also important that they provide us with market feedback, which directly informs our product development.
How do you enter new markets?
Entering a new market involves comprehensive preparation. We typically spend up to a year analyzing regulatory frameworks, certification requirements, grid connection conditions, and simulating use cases before signing a partnership agreement. In the energy sector – one of the most heavily regulated industries – we believe this preparation is essential for a successful market entry.
What types of storage systems are currently driving your business?
Our portfolio ranges from small three-phase residential systems starting at 6 kWh up to industrial systems exceeding 1 MWh, and recently even beyond 4 MWh with our Industrial XL solution. Across markets, approximately 70–80 percent of our business is currently generated in the residential and commercial segment. Utility-scale and large industrial applications account for roughly 20–30 percent.
Does this apply to all countries?
However, market dynamics vary significantly by country and change rapidly. For example, the Czech residential market experienced a boom after 2020, but two years later demand collapsed. At the same time, ancillary services and utility-scale applications — previously considered unattractive — are now emerging as major drivers.
Poland is considered a prime example for PV development and expansion in CEE.
In Poland, residential demand has declined significantly since 2023. Three years ago, we received constant inquiries from Polish companies. Last year, activity slowed considerably. We expect increasing development of behind-the-meter and standalone applications in the near future.
How challenging is the regulatory environment in Central and Eastern Europe?
The biggest challenge is the volatility. Regulatory frameworks, grid connection requirements, and certification requirements change frequently, sometimes without warning.
Do you have an example?
In the Czech Republic, for instance, the certification requirements were changed from one month to the next. The market practically ground to a halt. No one knew which systems could still be installed. Similar changes occurred again a year later.
So this constant back and forth is killing business?
This uncertainty is not good for investors, especially for storage projects with longer lead times. Even residential construction projects are often dependent on subsidy programs, and the application process can take months. If the regulations change before commissioning, systems can be installed but not connected to the grid. Stable framework conditions are crucial for us. That’s why we prefer markets that have already undergone initial regulatory adjustments and offer predictable conditions.
Would you say that Eastern Europe is a more difficult market than Western Europe?
I wouldn’t say more difficult, but different. In developed markets like Germany, the Nordic countries, or the Netherlands, regulatory clarity ensures investment security. Revenues can be predicted more reliably. The disadvantage of mature markets lies in stronger competition and higher regulatory requirements. In emerging markets, the biggest challenge is navigating the changing environment and adapting quickly.
What role do subsidies play in Central and Eastern Europe?
Subsidies remain the most important driver of the residential energy storage market in many countries, but especially in Central and Eastern Europe. When subsidies are available, demand increases dramatically; when they are withdrawn, market growth slows significantly.
What about the utility sector?
Subsidies also continue to play a significant role in the industrial and utility sectors, although investments in commercial applications are increasingly profitable even without subsidies. In Northern Europe, for example, favorable conditions for ancillary services have enabled projects with payback periods of less than three years in recent years – entirely without subsidies.
These are exceptionally short payback periods – how is that possible?
These exceptional returns are now the norm. They can be achieved in an environment with stable market mechanisms that attract investment. In the long term, ancillary services and grid stabilization are likely to become the most important sources of revenue for large-scale storage systems and reduce their dependence on subsidies.
Do you expect to see more grid-supporting storage solutions in the future?
Yes. We anticipate an increase in both grid-connected and stand-alone storage solutions. Grid stability requirements are rising. Frequency and voltage fluctuations are posing ever greater challenges across Europe. With the increasing share of renewable energies, maintaining grid stability within the required parameters becomes more complex. This leads to a structural demand for storage systems that can provide balancing and ancillary services.
How do you see the development of the European market in the East and West?
In developed markets, I expect continued growth in residential energy storage, with subsidies continuing to play an important role. In the commercial and utility sectors, a clearer and more stable business model is emerging – increasingly independent of subsidies. Requirements for grid stabilization, dynamic pricing models, and the expansion of markets for ancillary services will create stronger economic incentives. Dynamic tariffs and market-oriented mechanisms, combined with balancing energy services, will help ensure that investments quickly pay off and that revenue models for energy storage projects are economically viable.
What is your conclusion for Central and Eastern Europe?
Fenecon’s strategy in Central and Eastern Europe focuses on long-term partnerships, regulatory understanding, and technical adaptation to local conditions. Although country-specific market uncertainties continue to pose a challenge, the increasing need for grid flexibility to improve stability will further drive demand for battery storage systems across the region.
This interview examines Econergy Int. Ltd.’s strategy, market dynamics, and operational approach, highlighting technical, financial, and regulatory factors shaping large-scale energy storage deployment across Europe.
Munich, 05. März 2026
The interview features Joshua Murphy, who progressed from storage design to head of the energy storage division and now oversees business strategy, contract design, financial modelling, and route to market contracting. Founded in 2009, Econergy operates in seven European countries, combining local expertise with international financing to develop photovoltaic, wind and battery storage projects. The discussion addresses market opportunities, including Germany’s high revenue potential relative to growth in Central and Eastern Europe, as well as challenges such as grid congestion, regulatory reforms, project readiness, and the shortage of skilled labour. The interview also explores hybrid battery-solar projects, innovative designs including agrivoltaics, and the broader geopolitical and energy policy context influencing renewable integration.
To start, can you tell us a bit about your journey into the energy storage sector?
My background is rooted in utility stage solar and storage design, supported by earlier work at SMA in application engineering. I joined econergy as the head of storage design and integration. As the company’s strategy evolved, I moved into the role of Head of Energy Storage to support all battery operations. Today, my responsibilities center on business planning, forecasting, contracting, and coordination with project finance teams.
Where are the operational markets of Econergy geographically?
Econergy operates in seven key markets: Romania,Italy, the UK, Germany, Poland Greece, and Spain, with local offices staffed by development, legal, and grid experts.
Why is local presence essential for project development?
Local presence is critical for effective project development, particularly in land acquisition, permitting, grid connection processes and stakeholder engagement. Market maturity varies across regions. Germany offers a high number of ready-to-build projects, while Central and Eastern Europe remain more focused on development pipelines.
How is the company’s operational scale structured across markets?
Local teams of 15 to 40 people manage development, permitting, finance, and operations in key markets. Madrid hosts specialised project finance teams managing multiple projects’ financing and debt arrangements. In some countries, such as Germany where we are building our operations and pipeline, we are supported by local expertise
How is your financing structured for projects?
Our financing structure combines equity and debt mechanisms. Equity is raised through listings, strategic investors, bonds on TASE (ECNR), and private equity from insurance companies and funds. Debt financing typically consists of non-recourse project-level debt covering 60–80% of project costs, sourced regionally. All projects undergo rigorous technical, financial and legal due diligence by third-party advisors to ensure bank and investor confidence.
What grid connection challenges do you face in Central and Eastern Europe?
Grid limitations across Europe can slow project deployment. Some market participants secure connections speculatively for resale. Regulatory reforms are underway in the UK, Germany and countries in Central and Eastern Europe, including Romania, to improve access and streamline processes. Delays in grid connections can be a problem, as they restrict capital deployment and affect economic growth.
What are the current market dynamics and revenue opportunities for battery storage across Europe?
Germany presents high revenue potential due to market liquidity, price volatility, and feed-in tariff structures that enable profitable trading for batteries. Central and Eastern European markets are growing, with government incentives such as Poland’s capacity market, though overall revenue levels remain lower. Maintaining a presence across multiple markets supports diversification and balances opportunity with risk.
How does the company approach hybrid battery-solar strategies?
The company integrates battery storage with solar assets to optimise market participation and reduce exposure to price volatility. Batteries are increasingly essential for new solar-parks, marking a shift from standalone solar. This approach allows natural hedging, charging during low-price periods and discharging at peak prices, improving asset economics.
What is the company’s approach to project development and acquisition?
Greenfield development focuses on robust planning, connection readiness, and securing permits. Strategic acquisitions target ready-to-build projects to gain a foothold in competitive markets such as Germany, despite premium costs. Over six months, due diligence was conducted on more than 60 projects in Germany to identify optimal opportunities.
What technical and operational factors influence project success?
Component reliability is critical, with banks assessing spare parts availability, warranties, and manufacturer credibility to reduce risk. The complexity and maintenance requirements of trackers affect adoption decisions compared with fixed systems. Local conditions such as altitude, sun exposure, and weather variability directly influence solar production yields.
How do market incentives and support mechanisms affect battery project viability?
Capacity markets in Poland provide long-term contracts that reward battery availability and support grid stability. European funding grants for battery capital expenditures accelerate project feasibility. Projects with government contracts enhance bankability and reduce investment risk.
How do you see the German market in comparison?
In Germany, the market has historically been energy-only, and while no final decision has been taken yet, the government is considering the introduction of an ad-hoc, market-wide capacity mechanism for delivery around 2031. Current proposals envisage procurement of up to 41 GW of de-rated capacity through competitive, technology-neutral tenders, potentially including longer-term contracts for new capacity. If implemented, this would materially improve revenue visibility and strengthen the investment case for flexible assets such as battery storage, alongside energy and ancillary services revenues.
What challenges do competition and talent shortages create in the market?
Competition is intense for grid connections, projects, and supply chain resources. There is a growing need for experienced professionals in construction, commissioning, and battery operations. Grid operators are often under strain, limiting the timely processing of connection requests and slowing market growth.
How does leadership and corporate culture influence the company’s operations?
The company was founded by two longtime friends, Eyal Podhorzer and Yoav Shapira with complementary operational and financial skills. It maintains a long-term vision, focusing on owning and operating assets throughout their lifecycle rather than pursuing a build-and-flip strategy. That approach influences everything, from disciplined capital allocation to technical execution and risk management.
As a publicly listed company, we operate with a high level of transparency. This creates internal accountability and reinforces trust with stakeholders across all markets in which we operate.
What are the key market trends and future outlook for battery storage in solar projects?
Hybrid projects are expected to become the standard, with most new solar projects incorporating battery storage for resilience and revenue optimisation. Innovative designs, including agri-photovoltaics and adjusted solar-park orientation, aim to optimise generation timing. Batteries will play a central role in maintaining grid stability as fossil fuel generation declines.
What environmental and technical challenges does the company face?
Grid balancing through battery storage is essential to manage solar intermittency and maintain energy system stability. Physical and regulatory complexities, such as landowner negotiations, permitting timelines, and varying national regulations, present ongoing hurdles. Monitoring and managing component warranties, technical advisors, and contingency plans are critical to project success.
What is the current status on the companies pv-portfoloie in CEE?
The company’s pv-portfolio in both Romania and Poland is reflecting a strategic balance between operational projects and a robust development pipeline. In Romania we have 390 MW already in operation, complemented by 58 MW ready to connect and ~1GW under construction. Projects in pre-construction add 460 MW, while 1,4GW are under license, bringing the total development pipeline to 3,4GW. In Poland, 52 MW are operational, 105 MW are in pre-construction, ~900 MW are under license, and 1,4 MW are at the initiation stage, totaling to about 2,5 MW in development.
What do you consider your flagship projects in Central and Eastern Europe?
Our flagship projects in the region are undoubtedly Parau 1 and Parau 2 in Romania. Parau 1 combines 92 MW of photovoltaics with a 70 MW / 140 MWh battery storage system. Parau 2 has 343 MW of photovoltaics and a 150 MW / 300 MWh battery storage system. Parau 2 secured a 15-year contract for difference at €49.4/MWh in Romania’s first CfD auction.
How do geopolitical factors and energy policy affect battery adoption?
Batteries reduce exposure to volatile gas prices by storing low-cost renewable energy. Perspectives on nuclear energy vary, with small modular reactors potentially complementing renewable generation. Growing energy demand from data centers drives the need for stable power, supporting diverse solutions including batteries and nuclear.
As solar becomes a standard business asset in Central and Eastern Europe, returns increasingly depend on operational management, market responsiveness and effective digital systems.
Munich, 12. February 2026
For most businesses, the decision to invest in solar energy has long been settled. Solar plants, together with energy storage systems, have moved beyond experimentation and now form part of core operational strategy – also in Central and Eastern Europe (CEE). The decisive factor is how these assets perform financially. Recent experience highlights a clear shift within the energy sector: the decisive factor is no longer the installed power alone, but how that power is managed. As solar generation expands and price volatility increases, value creation depends on efficient operational control rather than on production volume.
Maximising revenue through intelligent management
Timely fault detection, accurate production monitoring and intelligent energy management increase revenue from existing infrastructure. Smaller, well-managed projects therefore often deliver higher returns than larger facilities that operate passively and respond too slowly to change. Electricity prices now fluctuate several times a day. Under these conditions, value is created by deciding when to store energy and when to sell it to the market.
Energy storage as an investment asset
Battery energy storage systems (BESS) increasingly function as investment assets rather than cost-saving tools. When connected to the grid, they can generate revenue by providing balancing services. In such cases, operation is typically handled by a balancer who manages charging and discharging to capture favourable market prices. The underlying logic is straightforward: low prices favour storage, while high prices favour export. However, these decisions require forward planning rather than real-time reaction.
Optimising storage
Maximum efficiency is achieved when storage is managed through specialised software in the form of an intelligent energy management system. These systems forecast consumption, market prices and solar generation to identify optimal charging and selling scenarios. As a result, payback periods for storage systems can be reduced to a few years. In 2026, businesses seeking higher efficiency must address price volatility with responsive operational strategies. Only reliable energy management systems can continuously monitor markets and optimise whether energy is sold or used internally.
Grid constraints affect revenue potential
As solar and wind capacity continues to expand across Europe, production curtailments caused by grid constraints are becoming more frequent, even when electricity has a market value. This directly reduces potential revenue. Grid conditions therefore represent a growing financial factor. In 2026, effective solar operations require close alignment with grid requirements. Facilities without adequate management systems may be forced to reduce or halt production, while those able to respond quickly can protect revenues and avoid losses. Solar energy facilities, particularly energy storage systems, now depend entirely on software. These systems control production, storage, grid communication and responses to market signals. Disruptions, unclear responsibilities or dependence on a single technology provider can directly affect business continuity and revenues. Cybersecurity has therefore become a core operational concern rather than a purely technical issue.
Operator competence drives financial outcomes
By 2026, evaluating energy storage systems solely on technical specifications will no longer be sufficient. The competence of system operators and the way systems are managed will be equally critical. As energy storage directly affects power supply stability, software failures or cyber incidents can lead not only to downtime but also to significant financial losses. Reliable software providers, secure system architectures and clear control over data flows are becoming as important as the efficiency of batteries or solar modules. Reducing technological dependencies is essential to ensure that energy assets support business performance.
Active management is the key to success
Rapid decision-making, responsiveness to market and grid signals, and secure operational management are increasingly making the difference between economically successful and less successful projects. By 2026, returns will no longer depend solely on the size of a solar generator, but on how actively and effectively it is managed.

Trinasolar’s head of Eastern Europe shares why she expects the region to be among the world’s fastest-growing solar markets over the next ten years.
Munich, 31. January 2026
What are your company’s current activities in Central and Eastern Europe?
Trinasolar has significantly expanded its presence across Central and Eastern Europe over the past two years. Today, we are active in 17 out of 21 countries in the region, with particularly strong momentum in the Baltics, Romania, Ukraine, Poland, and the Czech Republic.
What are your best-selling products in the region?
On the solar side, Trinasolar supplies high-efficiency n-type modules for utility-scale, C&I, and residential customers, and advanced tracking and fixed-tilt systems for the utility-scale segment.
Are you seeing increasing interest in storage systems in CEE?
Trina Storage is rapidly scaling in Eastern Europe, where we are already delivering for multi-MWh BESS projects in Lithuania, Estonia, and Romania, with additional projects advancing across Poland and other parts of the region. With increasing needs related to grid stability, flexibility, curtailment mitigation, and reactive power compensation, we see growing demand for hybrid solar-plus-storage solutions — an area where our integrated approach creates strong added value.
What makes the CEE region a focus area for your expansion?
Central and Eastern Europe is unquestionably a strategic growth region for us. Eastern Europe differs from Western Europe in several ways — particularly in development stage, regulatory frameworks, and energy-security needs — which makes our localized expertise especially valuable.
How does your company stand out in the CEE market?
A key differentiator is our localized, customer-centric approach. Each country is treated as a unique market: the team first seeks to understand its specific regulatory environment, grid requirements, and customer needs, then tailors the right technology and support accordingly.
What do customers in the region expect from Trinarsolar?
Over the past years, we’ve seen that customers in Eastern Europe increasingly rely not only on our products, but on our cross-regional experience, allowing us to act as a trusted advisor throughout project planning, procurement, grid integration, and long-term system performance.
What are your goals for 2026?
Looking ahead to 2026 and beyond, we will continue to follow market fundamentals and prioritize the largest and fastest-growing countries, while staying agile and present in emerging opportunities.
How is Central and Eastern Europe special?
In a global context CEE stands out because it combines strong ambition for new PV utility systems and BESS capacity, significant grid expansion needs, growing reliance on private financing as well as developing and rapidly maturing regulatory frameworks.
Do certain CEE countries offer particularly favorable conditions for development?
One of the unique strengths of the Central and Eastern European region is its diversity in market maturity. With 21 countries at different stages of development, the region offers a balanced and continuous flow of opportunities. Even when certain markets are slow due to regulatory changes or external pressures, others accelerate—allowing us to maintain a steady pipeline and stable supply across the entire region.
Can you give some examples?
From a market standpoint, several countries stand out today. Romania has emerged as one of the fastest-growing markets thanks to its National Recovery and Resilience Plan (NRRP) backed auctions, strong investor appetite, and a robust pipeline across both PV and storage. The Baltic states — particularly Lithuania and Estonia — are also frontrunners, especially for BESS. The market is supported by clear regulatory frameworks and a strong focus on energy security. We recently announced a major BESS project in Lithuania with Stiemo and more are underway.
Poland is considered an exciting and matured PV and BESS market. What do you think?
Poland continues to evolve rapidly, with increasing interest in utility-scale PV, hybrid systems, and PPA-based models. Bulgaria also consistently delivers close to 1 GW per year purely on market economics, despite having almost no PV subsidies. Other countries such as the Czech Republic, Hungary, and several Balkan markets are regarded as strategically important for Trinasolar.
How would you describe your overall footprint in CEE?
The diversity of regional markets and their specific challenges underpins our presence across the region and our focus on supporting customers in the Eastern European markets, covering modules, tracker systems and energy storage solutions.
Can projects in CEE thrive without EU funding?
Absolutely. While EU funding has historically played an enabling role — especially for early BESS and grid-support projects — the landscape is rapidly changing. In many CEE countries, we already see robust development without subsidies.
Do you have any examples?
Across Central and Eastern Europe, market dynamics vary widely. In the Baltic States, many large-scale projects have been financed entirely with private capital, and momentum increased further after the Baltics disconnected from the Russian grid in February 2025. In Poland, utility-scale PV has long been driven by PPA-based and merchant models. Bulgaria, despite offering almost no PV subsidies, consistently delivers around 1 GW of new capacity each year, driven purely by solid project economics. Non-EU markets such as Albania are expanding rapidly, fueled by strong local demand and favorable economic conditions. Even in Ukraine, solar and battery storage projects continue to move forward under wartime conditions, supported by international donors, private investors, and duty exemptions.
How do you explain the shift from subsidies to private financing? Across Europe, policymakers have moved away from subsidizing individual technologies and projects. Instead, states are focusing on creating a conducive environment for electricity systems. They are achieving this by reforming balancing energy markets, establishing capacity markets for battery storage systems, strengthening grid interconnections, and placing greater emphasis on energy security and reliability. As a result, more photovoltaic and storage projects are now being developed by private companies that prefer financing through financial institutions rather than EU subsidies. This approach offers greater flexibility and helps to avoid the complexities of public tendering procedures.
How do you see the PV and BESS market in CEE evolving over the next decade compared to other regions?
Over the next ten years, Central and Eastern Europe will move from being a “catch-up” region to becoming a frontrunner in innovative solar and energy storage models. Several forces are driving this transformation, including REPowerEU targets and broader EU climate goals, heightened energy‑security needs following the war in Ukraine, rapid electrification and industrial decarbonization and ongoing grid modernization with new capacity mechanisms supporting battery storage. Together, these trends are steering the market from primarily residential installations toward commercial, industrial, and utility‑scale projects, with hybrid PV + storage solutions playing an increasingly central role. BESS is emerging as essential infrastructure for grid stability, flexibility, and curtailment mitigation.
How will policy shape this future in CEE?
We’re witnessing a clear policy evolution across Europe. The region is moving away from direct, technology‑specific subsidies and toward building an enabling market environment—through reformed balancing markets, stronger interconnections, and capacity markets designed to enhance flexibility. As a result, more PV and BESS projects in Central and Eastern Europe are now financed by private developers, PPA structures, and financial institutions, giving the region greater resilience and momentum. Looking ahead, we expect CEE to become one of the world’s most dynamic solar and storage markets between 2025 and 2035, driven by robust demand, strategic policy frameworks, and the growing need for flexible, reliable, and secure energy systems.

In this interview, the managing director of CCE Romania explains the role of solar energy in the current reforms and the main challenges in the country’s transition from fossil energy production to low-carbon systems.
Munich, 04. December 2025
With fifteen years of experience in the Romanian energy sector, Alexandru Matei Fatu, managing director of CCE Romania, has played an active role in its transformation toward decarbonisation. The country is experiencing a rapidly accelerating shift from traditional CO₂-based power generation to photovoltaics and other low-carbon technologies. In this interview, Fatu discusses how this transition is reshaping established energy structures, redefining approaches to power generation, grid stability and sustainability, and outlines the key opportunities and challenges for solar energy in Romania.
What is your view on the current energy landscape in Romania?
Romania’s energy landscape has long been characterised by a diverse energy mix. Coal, natural gas, hydropower and nuclear power traditionally formed the foundation of the country’s electricity supply. In the early 2000s, Romania was a net exporter of electricity and played a key role as a regional energy hub in Southeast Europe.
When did this change start?
With EU market integration and a gradual decline in domestic generation capacity, Romania became an electricity importer. However, this appears to be changing. Through the transformation from CO₂-based to CO₂-neutral production, Romania is once again becoming a net exporter. Investments in photovoltaics and wind energy are increasing.
What role does coal play in the country’s energy mix today?
The share of coal in electricity generation has fallen from around 30 percent at the beginning of the 2010s to about 15 percent in 2024. Wind and solar energy now supply around one-fifth of national production. Hydropower remains an important pillar of the system, and nuclear energy also plays a limited role in maintaining security of supply.
What is the population’s attitude towards photovoltaic projects?
One aspect that distinguishes Romania’s energy transition is the constructive attitude of local communities towards renewable energy projects. Unlike in some European countries, Romania is experiencing openness and cooperation. Municipalities and local authorities recognise the benefits, ranging from new, future-proof jobs and improved infrastructure to increased tax revenue. Partnerships at the municipal level form part of our development success in Romania.
What are the challenges for project developers?
In my view, the biggest obstacles are administrative complexity and limited grid capacity. Although the legal framework has improved in recent years, regional differences still exist in the permitting processes. Inconsistent regulations complicate the approval process and lead to delays.
What ist he situation on grid connection points?
The availability of suitable grid connection points also remains insufficient. However, grid connection and building permits can now be applied for concurrently, which has already considerably shortened project development time. A capacity tendering system is intended to provide greater transparency and planning certainty starting in 2026. If implemented effectively, this may represent a benefit for investors and project developers.
Where do you see the strength of your branch?
Certainly in our multidisciplinary experience and close collaboration with regulatory authorities and grid operators. We can also manage project financing without EU subsidies. We reliably secure projects with long-term power purchase agreements, and this is also supported by banks.
How do you assess the next 10 years?
By 2035, Romania’s energy landscape may have fundamentally transformed. Renewable energies are expected to dominate electricity generation, complemented by storage solutions and digitally optimised grids. The participation of prosumers and energy communities will hopefully contribute to the development of a more decentralised and thus more resilient system. Hybrid concepts combining photovoltaics, battery storage and green hydrogen appear to represent the next phase of innovation. We are already investigating how combined photovoltaic and hydrogen plants can contribute to decarbonisation and system flexibility.
With abundant sunlight, Albania has the potential to diversify beyond hydropower. Professor Lorenc Malka explores how solar energy and storage could reshape the nation’s energy future.
Munich, 14. November 2025
Albania’s geographical location offers strong potential for photovoltaic deployment. Prof. PhD Eng. Lorenc Malka from the Energy Department at the Polytechnic University of Tirana provides insights into the current status, future scenarios, opportunities, and barriers for deploying photovoltaic power plants and Battery Energy Storage Systems (BESS) in the country.
Prof. Malka, what is the Energy Situation in Albania?
The electricity system in the Republic of Albania includes electricity generation, transmission, distribution, market operation, and trading. The goal is to provide electricity to both commercial customers and residential end-users. These activities are carried out by entities licensed by the Energy Regulatory Authority (ERE), in accordance with the amended Law no. 43/2015 “On the Electricity Sector.
What is the status on renewable energy?
On the supply side, Albania’s power sector is almost fully decarbonised, relying primarily on hydroelectric power, which accounts for approximately 95 percent of electricity generation. As of 31 December 2024, the country’s total installed electricity generation capacity is approximately 3,213 MW. This includes a 98 MW thermal power plant that never became operational due to a cooling system failure.
What is the grows of photovoltaics in recent years?
Total installed power increased by about 537 MW compared to 2023, mainly due to the addition of photovoltaic renewable energy sources. According to the 2024 ERE Annual Report, total domestic electricity generation reached 7,836,626 MWh. Of this, 4,371,085 MWh (55.7 percent) was produced by KESH sh.a, the Albanian Power Corporation, while 3,465,541 MWh was generated by other power producers.
How much PV capacity is installed in Albania?
In 2024, installed photovoltaic capacity reached 449.09 MW, with actual electricity generation amounting to 489.4 GWh. Of this, PV plants operating under feed-in tariff (FIT) contracts produced 67,700 MWh, while those participating in the liberalised electricity market generated 158,105 MWh. The remainder came from other plants.
Will electricity demand increase in the future?
On the demand side, total energy consumption in Albania has nearly doubled compared to 2005, with current usage around 24 TWh. The transport sector accounts for 38 percent, the residential sector for 25 percent, and industry for 20 percent; the remainder is consumed by other sectors. Fossil fuels dominate, making up more than 60 percent of annual national energy consumption. Annual electricity consumption includes both regulated and deregulated market segments.
Albania is well positioned for decarbonization with hydropower – so why photovoltaics?
Heavy reliance on hydropower makes Albania vulnerable to climate variability. In recent years, there has been a greater focus on diversifying energy sources, with the government actively promoting renewables. Solar is already well developed and feeding electricity into the national transmission and distribution network, while wind energy remains at an early stage. The installation of renewable energy sources—especially photovoltaics—has grown, particularly as support frameworks and policies have become more favourable to PV compared to other renewables.
The interview was conducted by Manfred Gorgus.

Gas wird nach Ansicht von Fachleuten eine zentrale Rolle in der polnischen Energiewende spielen.
Bei einer Debatte unter dem Titel „Polens Energiezukunft und die Rolle von Gas“ am Dienstag dem vierten November im Pressezentrum der Polnischen Nachrichtenagentur PAP betonten Vertreter von Regierung und Energiewirtschaft, dass Gas zum einen Übergangsbrennstoff sei, zum anderen auch Stabilisator des Energiesystems sei.
Gas – Kernkraft – erneuerbare Energien
Vertreter des Energieministeriums erklärten, dass Polen sich in einer Phase der Transformation befinde. Derzeit arbeite man am Nationalen Energie- und Klimaplan, der die Ziele für 2030 und 2050 festlege. Neben dem Ausbau erneuerbarer Energien und der Vorbereitung des ersten polnischen Kernkraftwerks spiele Gas eine wichtige Rolle, um die Versorgung in der Übergangszeit – bis zu 100 % Erneuerbare und Kernkraft – zu sichern und die Abhängigkeit von Importen vor allem aus dem Osten zu verringern. Das Ministerium plant, bis Ende des Jahres ein Strategiepapier fertigzustellen, das die Grundlage für Maßnahmen zur Versorgungssicherheit und Wettbewerbsfähigkeit schaffen soll..
Energieunternehmen mit konkreten Plänen
Der staatlich kontrollierte Energiekonzern PKN ORLEN S.A. (ORLEN) plant, bis 2035 Gaskraftwerke mit einer Gesamtleistung von 4,3 GW zu errichten. Weitere 12,8 GW aus erneuerbaren Quellen sollen bis dahin fertiggestellt sein. TAURON Polska Energia S.A. (TAURON) arbeitet an Wasserstoffprojekten. Dalkia Polska, die polnische Tochtergesellschaft des französischen Energiekonzerns EDF (Électricité de France), ist auf Fernwärme, Energieeffizienz und lokale Energielösungen spezialisiert und setzt für die Zukunft auf eine Kombination aus Gas, Biomasse und Wärmepumpen.
Gas nur als Brücke
Die Experten waren sich einig, dass Gas in den kommenden Jahren eine Brückenfunktion übernehmen wird. Gaskraftwerke gelten als vergleichsweise saubere Energiequelle, die Polen auf dem Weg zu einer klimaneutralen Energieerzeugung eine stabile Stromproduktion in einem zunehmend volatilen Energiemarkt gewährleisten soll. Sollte das polnische Kernkraftwerk gebaut und an das Netz gehen, könnte es die stabile Komponente in der künftigen Energieerzeugung darstellen. (mg)
RWE baut in Gundremmingen einen Batteriespeicher mit 400 Megawatt Leistung und einer Speicherkapazität von 700 Megawattstunden. Der neue Großspeicher nutzt die Netz-Infrastruktur des ehemaligen Kernkraftwerks, was großer Vorteil bei der Umsetzung des Speicherprojektes sein dürfte.
Das Unternehmen investiert rund 230 Millionen Euro in das Projekt. Der Baustart wurde am 29. Oktober 2025 mit einem symbolischen Spatenstich im Beisein des bayerischen Ministerpräsidenten Markus Söder und RWE-Vorstandschefs Markus Krebber offiziell eingeleitet.
RWE plant, die Inbetriebnahme des Batteriespeichers Anfang 2028 abzuschließen. Nach Fertigstellung soll die Anlage dazu beitragen, kurzfristige Schwankungen im Stromnetz auszugleichen. Dafür werden rund 200 Container mit etwa 850.000 Lithium-Eisenphosphat-Batteriezellen installiert. Der Speicher wird Strom für knapp zwei Stunden mit voller Leistung abgeben können.
Integrationspartner ist H&MV Engineering, ein Unternehmen mit über 1450 Angestellten, das nicht nur im Bereich der erneuerbaren Energien, sondern auch als Energieversorgungsunternehmen und mit Datenzentren unterwegs ist. Durch die Übernahme der Skanstec Gruppe Anfang 2024 hat H&MV Engineering ist ein europaweit führender Anbieter von spezialisierten Planungs-, Ingenieur- und Baudienstleistungen mit 400 Mio. € Umsatz mit 22 Standorten im EMEA-Raum entstanden.
Auf dem Gelände in Gundremmingen sind laut RWE weitere Energieprojekte vorgesehen, darunter ein Solarpark und ein neues Gaskraftwerk. Der Solarpark darf als Ergänzung zum Großspeicher verstanden werden. Das Gaskraftwerk wird fossile Brennstoffe nutzen und ist technisch als Backup für erneuerbare Energien gedacht. (mg)
Founded in 2020 in Warsaw, Menlo Electric has maintained a strong international focus from the very start, with 75% of its business taking place outside of Poland. Menlo Electric CEO Bartosz Majewski shares how the Poland-based distributor navigates a turbulent global solar market, tackling falling prices, declining residential demand, and fierce competition while maintaining capacity for future growth.
MUC 21.02.2025
Menlo Electric has grown rapidly in global solar and storage distribution. Can you share more about the company’s history?
Menlo Electric was founded in late 2020, initially as a subsidiary of an installation company. From the very beginning, our goal was to build an international distribution business, operating across multiple markets. This strategy was designed to mitigate the impact of fluctuations in demand within any single market, ensuring long-term stability and growth.
Did the strategy work?
It allowed us to expand rapidly, despite a market slowdown in Poland after net metering was phased out in Q1 2022. In 2021, we sold nearly 200 MW of solar components. The following year, our sales tripled to 600 MW, and in 2023, we reached 900 MW. Last year, we surpassed 1.3 GW of components sold. To put it in financial terms: in 2021, our revenue stood at €50 million, growing to €150 million in 2022. Over the past two years, despite the drop in component prices, our revenues have remained stable as we continued to grow in volumes.
What are Menlo’s main markets?
We are primarily active in Europe, the Middle East, and Southern Africa, with an emerging presence in the United States.
How have you experienced the sharp decline in component prices in recent years?
Module prices did decline at an unprecedented pace, at times falling by 30% per month, as seen in mid-2023 and again towards the end of 2024. Battery and inverter prices also plummeted. According to Bloomberg, battery prices declined in 2023–2024 at the fastest rate since 2017.At the same time, the European residential solar market contracted significantly. According to data from SolarPower Europe, residential installations in Europe shrunk by 30% in volume. When factoring in the impact of falling component prices, the market declined by more than 50% in value.
Can you share a concrete example of the impact of this slowdown?
For example, SolarEdge, a key manufacturer in the inverter and storage market, saw its quarterly sales drop from nearly $1 billion to approximately $200–250 million. As distributors and installers rushed to liquidate their stock in a shrinking market, intense competition drove selling prices significantly below purchase cost.
But the market for commercial PV and solar parks has picked up in Europe. Couldn’t that compensate for the lost share in the residential sector?
For modules, the impact was somewhat mitigated, as many of the same products can be used across both: residential and commercial & industrial (C&I) installations. However, the situation was far more severe for inverters and batteries, which are typically specifically designed for residential use and cannot be economically or technically repurposed for C&I applications.
A perfect storm, it seems?
Market contraction led to a huge oversupply, leaving many distributors struggling to unlock capital from their inventories, which in turn created cash flow challenges. As a result, several distributors faced serious financial difficulties.
Menlo Electric is active internationally. Did your strategy not allow you to compensate for problems in some markets with growth in others?
Interestingly, similar trends emerged simultaneously in different parts of the world, although for different reasons: In the United States changes to net metering regulations in California led to a sharp slowdown in the residential solar sector, putting U.S. distributors in a situation very similar to their European counterparts. In South Africa the residential solar market contracted significantly as ESKOM effectively addressed load shedding issues. By late 2023, power outages were already reduced, and by the first quarter of 2024, they were virtually eliminated. This removed a major driver for residential solar demand.
What’s the solution to this situation?
This intense crisis has actually driven increased cooperation between companies that previously operated purely as competitors. In the current market, distributors are buying and selling components among themselves across different regions, trying to rebalance supply and demand for various solar and storage products.
How have your suppliers, i.e. manufacturers, reacted to the crisis?
According to our experience manufacturer support has fluctuated. Particularly in the second half of 2024, when it became clear that the downturn was more prolonged than many had anticipated, several manufacturers scaled back or put on hold their support mechanisms for distributors. This has added further strain to an already difficult market.
Sounds like tough times and market consolidation
Overall, the industry is undergoing a significant reshuffle. Some distributors are reducing their international footprint, while others have gone out of business entirely. The coming months will likely bring further consolidation, as companies adapt to the new market realities.
How has the crisis hit Menlo Electric and how is it being dealt with?
It should come as no surprise that Menlo Electric has been significantly affected by the current crisis. As one of the youngest and fastest growing companies in this sector before the downturn, we did not have the time to accumulate substantial earnings that could serve as a financial cushion during such turbulent times. As a result, we have had to adjust our strategy, expanding our portfolio, focusing on key markets and increasing sourcing from other distributors across Europe. This approach allows us to remain agile while navigating the current market conditions.
So, what is your outlook for the future?
We remain optimistic about the future. Back in late 2020, Menlo was a company that could fit into a single room. In just three years, we scaled to €150 million in annual sales across four continents. I see absolutely no reason why we won’t rebound and return to our growth trajectory once the market stabilizes. Our priority now is to protect the foundation we have built over the past four years and position ourselves for renewed growth as soon as market conditions allow.
What key challenges did you face when expanding globally?
Running an international business in Poland, especially when expanding beyond the European Union, comes with unique hurdles. One of the challenges we experienced was finding a banking partner that could support our operations not only in Poland and Europe but also in key markets like the Middle East and South Africa. We quickly realized that there were only two banks with the necessary global footprint and presence in Poland. Fortunately, we were able to establish a strong partnership with one of them, HSBC Poland. It has provided us with tremendous support and flexibility over the years. The same applies to our partner KUKE, an insurance company belonging to Polish Development Fund Group. It has allowed us to extend insured credit limits to our clients not only across EU, but also e.g. in Ukraine and Southern Africa. With this kind of support, we will continue to build Menlo’s international presence.
Even though Menlo is internationally oriented, how do you see the future of the Polish PV market?
PV sales will remain stable for large systems. In my opinion, we will see more and more installations of energy storage in the residential market soon. The Polish electricity grid is a problem that needs to be addressed. It was and still is in a bad state and its rapid improvement is necessary for a further and sustainable expansion of photovoltaics.
Die polnischen Gasnetze sollen in Zukunft eine zentrale Rolle in der Energiewende des Landes einnehmen. Sie sollen neben Erdgas, auch zunehmend Biomethan transportieren. Um dies zu ermöglichen, sollen die Produktion von Biomethan gefördert, finanzielle Mittel bereitgestellt, und die Rahmenbedingungen für den Ausbau der Biomethanproduktion geschaffen werden. Noch handelt es sich allerdings um eine Absichtserklärung. Wie Regierung und Versorger sich die Transformation vorstellen, lesen Sie hier.
Polska Spółka Gazownictwa (PSG) ist Polens größter Verteilnetzbetreiber, der mit über 210 000 km Leitungslänge einen entscheidenden Beitrag zur Energiesicherheit in Polen leistet. Das Unternehmen will in Zukunft den Einsatz von Biomethan forcieren, um seine Gasinfrastruktur für die polnische Energiewende zu transformieren. Das ist ein Ergebnis der 29. Aufladetechnischen Konferenz vom 23. bis 24. September 2025 in Dresden.
Biomethan als Zukunftsenergie
Der Anteil von Biomethan im Energiemix soll maximiert werden, da es laut PSG klimafreundlich und ressourcenschonend ist. Erste Biomethananlagen sollen bereits erfolgreich ans Netz gegangen sein und zeigen das Potenzial dieser Technologie auf.
Polens Energiestrategie und Gassektor
Die polnische Regierung plant, ihre Energiepolitik bis 2050 grundlegend zu verändern, wobei der Gassektor eine wichtige Rolle beim Übergang zur CO₂‑neutralen Energieproduktion spielen soll. Das Vorgehen bei der Dekarbonisierung soll dabei pragmatisch erfolgen, mit Fokus auf erschwingliche Energiepreise und schnelle Marktintegration von Biogas und Biomethan.
Finanzierung und Zusammenarbeit
Die Entwicklung des Biomethanmarktes soll durch gezielte finanzielle Unterstützung gefördert werden, unter anderem durch Darlehen von Banken und den polnischen Entwicklungsfonds. Die Vernetzung von Forschung, Industrie und Politik soll den Aufbau von Kapazitäten für Produktion, Netzanschluss und Verteilung fördern.
Herausforderungen und Perspektiven
Neben technischen Herausforderungen bei Netzanbindung und Systemregulierung liegt ein Schwerpunkt auf dem Ausbau der Infrastruktur und der Schaffung marktgerechter Rahmenbedingungen. PSG sieht seine Aufgabe darin, die Versorgungssicherheit von Bevölkerung und Wirtschaft zu gewährleisten und die Rolle von Biomethan im Energiemix zu stärken.
Fazit
PSG soll als Schlüsselakteur der polnischen Energiewende mit der Förderung von Biomethan zur nachhaltigen Transformation des Energiesystems beitragen. Mit Geld, optimierten Rahmenbedingungen sowie politischer Unterstützung will Polen bis 2050 eine klimafreundliche und sichere Energieversorgung erreichen. Allerdings ist das Thema Biomethan ebenso wie Biogas noch schwierig, weil es aktuell noch keine zuverlässigen Rahmenbedingungen dafür gibt. Das war das Fazit der ersten Biogasmesse Polens vom 30. September bis 02. Oktober 2025. (mg)
Andreas Zyber has been working for various German companies in the Polish PV industry since 2011. Since 2022 he has been managing director of Quantumsolarpv GmbH, the German branch of a Polish PV wholesaler that is growing across Europe even in turbulent times. In our interview he reveals the secret of success in difficult times.
How did you get into photovoltaics?
By a roundabout route. I studied mechanical engineering in Poland and obtained an engineering degree there. I then studied business administration in Germany and graduated with a business degree. After managing business with Poland for a German commercial vehicle manufacturer for years, I decided to switch to the photovoltaics industry in 2011.
What motivated you to change?
A mixture of desire to build something new and enthusiasm for the technology. I was especially excited about photovoltaics because of its possibility to generate clean electricity for decades with comparatively small investments.
How would you describe your role in the Polish PV industry?
I come from the sales of commercial vehicles. These are technical products that require explanation. I have taken my experience into the PV industry and describe my first years in the industry as ambassador work for German photovoltaic technology in Poland where I succeeded in establishing partnerships for German companies in Poland. Some of the companies I worked for have received awards for their solutions and technologies in Poland.
If you could enter the industry again, would you do everything the same?
In 2011, the PV industry in Poland was just beginning. I am a B2B salesperson and have continued this work in the PV industry. If I could turn back time, I would personally invest in the production of PV components with German quality standards in Poland.
How can you best describe your current tasks in the market?
While I previously worked practically only for German companies in the Polish market, my job today is communication in both directions: selling products and services from Polish companies to the European market and products from European companies to the Polish PV market.
What products and services do you offer?
Our focus is on complete PV solutions, from small roof systems to system providers for large PV projects, roof systems and open space systems for customers in Poland and German-speaking Europe, i.e. Germany, Austria and Switzerland.
2023 seems to have been a difficult year for many Polish wholesalers. Was it also for your company?
A clear no. Our warehouse, marketing and logistics is based in Poland. Our German branch is located near Munich. From there we primarily serve customers in the DACH region and other Western European countries. Throughout Europe we deliver within 24 hours if the components are in stock. Our team is lean and all employees have experience in the photovoltaics industry. We work with flat hierarchies, which makes us fast and flexible. We think from the customer’s perspective and talk to the customer. The market seems to appreciate that.
How does the Polish PV market differ from other markets?
In my experience, price plays a bigger role in Poland than in Austria, Germany and Switzerland. We can offer reasonable prices, but as a young company we have to convince in all areas: fast and reliable delivery, good advice, attractive prices and flexibility when the customer is asking for changes in the order.
What developments do you see in the Polish PV industry for the next 6 months to 2 years?
The PV industry in Poland has developed into a stable market in recent years. Following the change of government, the PV industry will now receive billions in EU funds. This is one of many subsidies that Poland is expected to receive. This will lead to a further increase in PV installations in the country. Due to the outdated Polish power grid and its time-consuming upgrading, electricity storage will be an increasingly interesting investment in the next 12 to 24 months.
The 45 MW site in Estonia is now fully operational, with a 32 MWh battery energy storage system in development to enhance grid flexibility and support renewable integration.
Munich, 06. August 2025
Commissioned in 2024 with an installed photovoltaic output of 45 MW, the Raba solar park represents one of Estonia’s larger operational solar facilities to date. The project incorporates a 32 MWh battery energy storage system (BESS) to support grid reliability and mitigate solar intermittency.
Raba performing in line with projections As of July 2025, the Raba solar park is operating as expected, delivering approximately 40,000 to 44,000 MWh annually. The installation features bifacial modules from TrinaSolar, specifically the Vertex Dual-Glass-Bifacial model. Developed by Sunly and Metsagrupp and constructed by Smartecon, the solar park plays a key role in supplying clean electricity to the region.
Battery system already under construction
The battery storage system, initiated in 2024, is currently under construction and scheduled for completion by early 2026. The system is designed to offset fluctuations in solar generation, improving overall system flexibility and stability.
Financial backing
The project is supported by a €17.8 million loan from Swedbank. It represents a strategic investment in Estonia’s renewable energy infrastructure, contributing to national decarbonisation objectives and reducing fossil fuel reliance.
Estonia exceeds 50 percent renewables in domestic electricity in 2023
In 2023, for the first time, more than half of Estonia’s electricity was generated from renewable energy sources, with solar power accounting for approximately 20%. However, when including electricity imports, renewables comprised only about 30% of the country’s total electricity supply. Estonia has set an ambitious goal to meet all of its electricity needs with renewable energy by 2030.
Larger projects on the horizon
Estonia’s solar sector has seen the commissioning of several large-scale photovoltaic projects alongside Raba’s development: The Kirikmäe Solarpark, operational since 2024, contributes over 77 MW to the national grid, increasing overall generation capacity. Similarly, the Sopi Solarpark, online since 2025, adds a further 74 MW. Looking ahead, the Risti Solarpark is under construction and, upon completion in 2027, will be the largest photovoltaic installation in Estonia and the Baltic region, with a planned capacity of 244 MW.
Solar and storage strengthen Estonia’s energy autonomy
Together, these projects underscore Estonia’s increasing focus on utility-scale solar energy. According to official figures, Estonia has not imported any electricity from Russia since 2005. In 2023, the country completely stopped importing oil and gas from Russia. Estonia’s electricity supply is well integrated with neighboring EU countries such as Finland and Latvia, and the balance with Russia has been balanced since 2023. The disconnection from the Russian power grid will be completed by 2026 at the latest, effectively ending Estonia’s energy dependence on Russia for electricity. The integration of renewable energies therefore greatly increases the country’s independence and security of supply.
Lithuania-based software expert Inion reported a 48% increase in revenue to EUR 267,000 in the first quarter of 2025, driven by rising demand for AI-powered energy management solutions, particularly in the energy storage sector.
Munich, 02.July 2025
Inion Software is a fast-growing Lithuanian company specializing in energy management solutions for the renewable energy sector. The company recorded revenue of €181,000 in the first quarter of 2024, which increased to €267,000 in the first quarter of 2025 – an impressive increase of 48%. For the full year 2024, the company reports revenue of €1.2 million. Following the positive result in the first quarter of 2025, Inion Software expects to exceed this figure in 2025 as demand for digital energy solutions made in Europe continues to grow.
