We’re truly excited to share some big news: sun.store has successfully closed a €6 million seed funding round, one of the largest early-stage raises in Poland to date. This milestone marks the next chapter in our journey to make solar and storage procurement faster, more transparent, and truly pan-European.
The round was co-led by Contrarian Ventures, Market One Capital, and Movens Capital, with participation from FJ Labs, Push Ventures, and Aidiom. Together, this investor group brings a powerful mix of cleantech expertise, marketplace know-how, and international reach – exactly the combination needed to support our next stage of growth.
Why this matters for the solar industry
Procurement of solar and storage components in Europe has long been fragmented and inefficient. Too often, deals are still made through a patchwork of emails, phone calls, and spreadsheets — slowing down transactions, limiting access to supply, and creating price opacity.
We launched sun.store in October 2023 with a clear mission: to bring order, speed, and transparency to this process. By digitizing procurement, we’re not only helping installers, distributors, and EPCs trade more efficiently. We’re also laying the groundwork for the clean energy transition to scale at the pace Europe urgently needs.
Our traction so far
In less than two years, sun.store has become Europe’s largest B2B digital marketplace for solar components, achieving:
- 35,000 registered users across more than 25 countries.
- 2,500 unique buyers, from small installers to large distributors and EPCs.
- 1.4 GW of photovoltaic components traded – enough to power a city the size of Brussels.
- 1,000+ transactions facilitated every month, with an average order value of more than €8,000.
- A network of 500+ active sellers, collectively offering over €1.5 billion worth of components.
- Access to 200+ brands across 1,000+ European warehouses.
- Truly pan-European trade, with 90% of transactions happening across borders within the EU.
These numbers prove both the urgency of the problem and the scale of the opportunity in transforming how solar and storage equipment is sourced.
What’s next?
The new funding will allow us to:
- Accelerate product development: launching new features that make transactions faster, safer, and easier.
- Enhance merchant support: onboarding more sellers, expanding technical support, and ensuring product reliability.
- Grow our team: strengthening our commercial, product, and operational teams in Warsaw and beyond.
As CEO Agata Krawiec-Rokita explains:
“Our goal is simple: to bring structure, speed, and transparency to solar procurement. This funding gives us the resources to scale faster and expand our reach at a time when the sector needs it most.”
Co-founder Bartosz Majewski adds:
“We’ve been in the solar trenches long enough to know how fragmented and frustrating procurement can be. sun.store was built to give professionals the clarity they need in an increasingly complex market. The traction we’ve achieved in under two years shows how urgently this solution is needed.”
Our long-term vision
While our immediate focus is on solar and storage, our ambition is broader. We see sun.store as the digital infrastructure for all clean energy equipment, from heat pumps and HVAC to e-mobility infrastructure and electrical components.
Europe’s clean energy transition is vast and complex, but with the right tools, it can also be fast and scalable. sun.store is here to provide those tools.
Thank you for being part of our journey
This funding is not just about scaling a platform. It’s about enabling thousands of energy professionals across Europe to trade more confidently, efficiently, and transparently — and ultimately, to bring more renewable power online, faster.
We’re grateful for the trust of our community, our partners, and our investors. And we’re just getting started.
