The European solar market is expanding rapidly, but the way solar equipment is bought and sold remains outdated. Many installers, distributors, and EPC companies still use emails and spreadsheets to manage procurement, causing delays, inefficiencies, and confusion in this fast-growing sector.
Founded in late 2023 and based in Warsaw, sun.store aims to change that by digitising the entire process. It offers a B2B platform where buyers and sellers can find structured product listings, dynamic pricing, logistics, and financing options all in one place, making cross-border trading much smoother.
Today, sun.store closed a €6 million seed funding round, one of the largest for a Polish startup so far. The round was co-led by Contrarian Ventures, Market One Capital, and Movens Capital, with support from FJ Labs, Push Ventures, and Aidiom.
The fresh capital will help sun.store speed up its product development, grow its team, and expand across Europe's fragmented solar market.
Behind sun.store are founders Agata Krawiec‑Rokita and Bartosz Majewski, who bring real industry experience. They have seen the challenges solar businesses face with procurement firsthand and were motivated to build a platform that simplifies and speeds up the entire process.
Krawiec‑Rokita shares with TFN, "We noticed the problem troubling solar businesses: procurement was done largely via email and spreadsheets, making it slow, opaque and prone to errors. Seeing how this inefficiency limited growth for installers, distributors and EPC firms, we decided to build a platform that digitises and streamlines the process."
sun.store's goal is to make solar procurement faster, clearer, and more transparent. But founders don't want to stop at solar: they envision a future where sun.store supports all clean energy equipment, from heat pumps to electric vehicle chargers.
Unlike generic marketplaces or listing platforms, sun.store is fully transactional and tailored specifically for the workflows and complexities of solar procurement. Sellers can input structured product data with real-time pricing, while buyers benefit from instant quotes, flexible payment options, and integrated shipping services.
Krawiec‑Rokita adds, "Key differentiators include structured product data, dynamic volume-based pricing, integrated logistics, flexible payment options, and embedded financing. This end-to-end approach allows users to search, filter, quote, and close deals in real time."
This approach has paid off. sun.store now serves 35,000 users, including 2,500 active buyers across 25 countries, handling over €100 million in transactions in less than two years. The platform lists over €1.5 billion worth of products, making it Europe's largest marketplace for solar components, outperforming many traditional distributors.
Looking ahead, sun.store plans to use the new funding to add more features, bring on more sellers faster, and extend its reach beyond solar into the full clean energy equipment market.
"sun.store aims to become the default digital infrastructure for clean-energy equipment procurement across Europe, extending beyond solar and batteries to categories such as HVAC, heat pumps, e-mobility infrastructure, and electrical components," concludes Krawiec‑Rokita.
When asked for advice to other female founders, she adds: "Focus on delivering results, seek out diverse viewpoints, and don't let old industry habits hold you back. The energy transition needs fresh ideas and new leadership."
