Sun.store Secures €6m Seed Round to Digitize Europe’s Solar Procurement
Sun.store, a B2B digital marketplace for solar and storage components, has raised €6 million in seed funding, one of the largest early-stage rounds in Poland’s cleantech sector to date. The investment signals growing confidence in the company’s mission to modernize Europe’s fragmented solar procurement system and accelerate the clean energy transition.
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 investor consortium brings together expertise in cleantech, marketplaces, and international scaling – elements that Sun.store’s founders say are essential for the company’s next growth phase.
In Europe, sourcing solar and storage equipment has long been an inefficient and opaque process, often reliant on phone calls, emails, and spreadsheets. This slows down transactions, reduces supply access, and limits pricing transparency at a time when demand for renewable energy is surging.
Launched in October 2023, Sun.store set out to streamline this system. By digitizing procurement, the Warsaw-based company aims to help installers, distributors, and engineering, procurement and construction (EPC) firms trade faster and with greater transparency.
Agata Krawiec-Rokita, Co-founder and CEO, Sun.store: ”Procurement has been one of the biggest bottlenecks in solar deployment. Our goal is simple: to bring structure, speed, and transparency to the process. This funding gives us the resources to scale faster and expand our reach at a time when the sector needs it most.”
In under two years, Sun.store has become Europe’s largest B2B digital marketplace for solar components, with more than 35,000 registered users across 25 countries. The platform counts over 2,500 unique buyers – from small installers to large distributors – facilitating more than 1,000 transactions each month with an average order value exceeding €8,000.
To date, the platform has enabled the trade of 1.4 gigawatts of photovoltaic components, enough to power a city the size of Brussels. Its network of over 500 active sellers now offers €1.5 billion worth of components, representing 200 brands stored across 1,000 European warehouses. Notably, 90% of Sun.store’s transactions cross EU borders, underscoring its pan-European reach.
The fresh capital will fund product development, merchant support, and team expansion. The company plans to introduce new features to make transactions faster and safer, expand seller onboarding, strengthen technical support, and build its commercial and operational teams in Warsaw and beyond.
While the company’s immediate focus is on solar and storage, its ambitions are broader. Sun.store envisions becoming the digital infrastructure for a wider range of clean energy equipment, from heat pumps and HVAC systems to e-mobility infrastructure and electrical components.
Europe’s energy transition, the company argues, will require not just more renewable generation but also smarter, more efficient ways to source and distribute the hardware that makes it possible.
”This is about more than scaling a platform. It’s about enabling thousands of energy professionals across Europe to trade with confidence and transparency – and ultimately, to bring more renewable power online, faster,” said Krawiec-Rokita.
