In this exclusive interview, Agata Krawiec-Rokita, CEO and Co-founder of sun.store, explains how the company is reshaping Europe’s solar market with its digital B2B platform for PV components — setting new standards for transparency, accessibility and hassle-free purchasing for installers across the continent.
Munich, 02 July 2025
Can you give a brief description of your company?
sun.store officially launched in October 2023. Despite being a young company, we’ve grown rapidly: in under a year, we’ve surpassed 1 GW of traded components and €100 million in GMV, making us one of the fastest-growing solar marketplaces in Europe.
Your roots are in Poland, why did you start in the Netherlands?
We chose the Netherlands as our legal base due to its proximity to the Port of Rotterdam, the logistical heart of European imports. Being in the Eurozone also facilitates smooth financial operations across the continent. However, as our operational backbone is rooted in Poland and Central Europe, we’re actively considering moving our full operations back to Poland to stay closer to our core market and team.
What does your component portfolio look like?
Our strongest categories are solar modules, inverters, and battery storage systems. We are also expanding our offering in mounting systems and electrotechnical equipment to provide a more comprehensive solution for installers and distributors.
What services do you offer?
Beyond product sales, we provide logistics coordination and technical support in component selection. Our aim is to reduce friction in the purchasing process and enable smoother project planning for professionals.
What are your target markets?
We serve customers across all of Europe: from Germany, Poland, and the Netherlands to Spain, Romania, Italy, and beyond. Our model is built for scalability across diverse solar markets.
Who are your target groups?
Our primary customers are residential and small-to-mid-sized commercial & industrial (C&I) installers, as well as smaller wholesalers and regional distributors looking for better access to supply and prices.
What are sun.store’s unique selling points?
sun.store stands out through selection, price, and convenience. We aggregate a wide variety of verified offers, provide real-time availability, and simplify transactions in what used to be a very fragmented supply chain.
Is there a company philosophy?
Our goal is to make the solar supply chain more transparent, efficient, and accessible. By digitizing the buying and selling process, we help accelerate installations, reduce overhead, and ensure that clean energy reaches more rooftops, faster.
How would you describe your tasks in the company?
I am the CEO and co-founder of sun.store. I oversee sales and marketing, product development, and internal operations. My focus is on building a platform that truly reflects the needs of solar professionals, both today and in the long-term future.
What share does Poland and Central & Eastern Europe have in your sales?
Our roots are Polish, and the platform’s early transaction came largely from the Central and Eastern European region. In 2023, Poland represented over 56% of our gross merchandise volume (GMV). However, as we’ve scaled, the market mix has diversified significantly. By 2025, Germany represents nearly a quarter of our GMV, with the Netherlands, France, Italy, Romania, Czech Republic, and others making up a growing share. This confirms our international trajectory. While Poland and CEE are important to us, sun.store is now a truly European platform with a diversified and balanced customer base.
How has your business developed in Central and Eastern Europe?
The CEE region was foundational to our growth – it’s where our team, early adopters, and trusted partners come from. But over time, we’ve expanded westward. Today, Western Europe, particularly Germany and the Benelux region, plays a key role in our volume and revenue. That said, we remain deeply connected to the CEE region, and our infrastructure supports buyers and sellers from across Europe.
What are your priorities in each country?
While there are local nuances, we observe a broader trend across Europe: increasing interest in solar-plus-storage, especially in the residential and commercial rooftop segments. Utility-scale projects are also growing in specific countries, but small and mid-sized C&I installations are gaining momentum nearly everywhere.
How do the Polish roots affect your business – if at all?
Our Polish origins give us a strong base in Central Europe, but we operate with a pan-European mindset. This balance allows us to redistribute supply – for instance, when demand slows in one country – like in Poland in early 2024 – we help local distributors and installers sell their inventory into higher-demand regions like Germany or the Netherlands. It’s a built-in hedge against local market fluctuations.
Where do you see growth opportunities in the next 12 to24 months?
We see three clear short-term drivers: One is Residential and small C&I storage solutions – these are in high demand, especially in countries with evolving net-metering policies or energy price volatility. The second is Overstock clearance and arbitrage – as markets shift and inventories move, agile marketplaces like sun.store help suppliers find buyers for surplus or redirected stock quickly. The third is Digital adoption. Many solar professionals are moving online for procurement. Our company benefits directly from this shift, offering a scalable and easy-to-use alternative to traditional channels.
Where do you see growth within the next three to five years?
Several trends will shape the next chapter of solar. Solar-plus-storage will become standard in commercial & industrial projects. Renovation or let’s call it upgrading of older PV installations will become an increasingly important part of our business. I’m specifically thinking of replacing aging inverters and adding storage to existing pv-installations. Refurbishment, recycling, and second-life use of solar components will open a new circular economy segment. Software-driven optimization, including predictive maintenance, VPP integration, and dynamic energy management, will gain traction. And finally, digital B2B trade in PV will become mainstream – a shift we’re already enabling today.
