Overview
Solaregy is a German startup company focused on bringing sustainability into everyday life by turning unused window surfaces into sources of green energy. According to its official website, the company's mission is to create innovative solutions that help people reduce their carbon footprint and to contribute to the energy transition. Its first product, RaffSun, addresses the problem of increasing energy consumption and environmentally harmful electricity generation by using window areas for power generation while simultaneously providing shading. The company was founded by Morris Haid and Florian Legermann, both listed as Founder & CEO on the official site. Solaregy is based in Germany, as indicated by its .de domain, and operates as a private startup. The company positions itself at the intersection of renewable energy and building-integrated solutions, targeting the potential of glass fronts that currently let sunrays heat interiors unnecessarily. By combining power generation with shading, RaffSun offers a dual solution for windows. As of the available evidence, Solaregy remains an early-stage venture with a single flagship product and a small founding team.
