Press release from January 20th, 2026

Growth capital for scaling solar power on commercial rooftops – hellgrün quadruples revenue in the million-euro range.

Berlin, January 20, 2026 – We are further increasing our stake in the Cologne-based energy startup hellgrün and providing additional growth capital to scale photovoltaic projects on commercial properties. As part of the follow-up financing, Saxovent will become the largest shareholder of hellgrün alongside the founding team.

hellgrün enables the cost-effective implementation of on-site PV and direct power models on commercial rooftops – especially for retail, logistics centers, cold storage, and manufacturing industries. The company manages the entire process, from site assessment and financing to construction and long-term operation.

hellgrün has demonstrated that on-site PV on commercial rooftops can be implemented quickly, professionally, and at scale, without property owners or asset managers having to take on operational burdens. The progress made in 2025 was a clear signal for us to expand our investment. With this, we emphasize our commitment to supporting hellgrün’s long-term growth.

Thorsten Freise – CEO of Saxovent Renewables

The reason for expanding the commitment is the strong operational development: hellgrün quadrupled its revenue in 2025 in the million-euro range. From Saxovent’s perspective, this dynamic confirms the scalability of the model and the market demand in a segment where property owners and asset managers are under increasing pressure to pragmatically address ESG requirements and energy costs.
