In this exclusive interview, Agata Krawiec-Rokita — CEO and Co-founder of sun.store — shares how her team is transforming the solar industry with a digital B2B platform for PV components. Though headquartered in the Netherlands, sun.store has its roots — and its team — in Poland. The company is setting new standards in transparency of delivery, 24/7 shop access, and hassle-free shopping for installers across Europe — from West to East, North to South. Learn why they chose the Netherlands as their legal base and what they expect from the European market as a whole.

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.

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.
