We have been active in photovoltaics since 2004 and instaSOL PV systems from relatio are installed hundreds of times across Germany on all types of roofs. But we also planned and implemented some of europes largest power plants at the time of construction. Today we focus on the concerns of industry, trade and municipalities. The electricity generated by our systems is used directly and without detours, even without storage, by our customers, and excess electricity is fed into the grid and remunerated. In this way you not only save CO², but also receive electricity at a fixed, calculable cost.
