Warsaw-based sun.store, a solar-oriented trading platform connecting sellers and buyers, has secured €6M in seed funding, marking one of the largest early-stage rounds in Poland to date.
The round was co-led by Contrarian Ventures, Market One Capital, and Movens Capital, with additional backing from FJ Labs, Push Ventures, and Aidiom.
The fresh capital will accelerate the company’s product development, enhance merchant support, grow its team and bring speed, structure, and transparency to Europe’s fragmented solar procurement market.
sun.store: Digitising procurement end-to-end
For many years now, the sourcing of solar and storage components in Europe has been fragmented and inefficient, relying on a patchwork of emails, calls, and spreadsheets.
This process has limited access to supply, created inefficiencies, and slowed down the clean energy transition.
Launched in October 2023 by Bartosz Majewski and Agata Krawiec-Rokita, sun.store digitises procurement end-to-end, enabling installers, distributors, and EPCs to trade more efficiently.
“We launched sun.store with a clear mission: to bring order, speed, and transparency to this process,” says the company.
Agata Krawiec-Rokita, CEO of sun.store, 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.”
In less than two years, sun.store has emerged as Europe’s largest B2B digital marketplace for solar components.
The platform has over 35,000 registered users from over 25 countries and has attracted 2,500 unique buyers, ranging from small installers to large distributors and engineering, procurement, and construction (EPC) companies.
To date, it has facilitated the trade of 1.4 gigawatts of photovoltaic components, which is sufficient to power a city the size of Brussels.
The company claims to handle over 1,000 transactions, with an average order value of more than €8,000.
At present, the platform is supported by a network of more than 500 active sellers, who collectively offer an inventory valued at over €1.5B.
Additionally, sun.store provides access to more than 200 brands located in over 1,000 warehouses across Europe. Notably, 90 per cent of the transactions on the platform involve cross-border trade within the EU.
Bartosz Majewski, co-founder, 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.”
