Rielasingen-Worblingen – September 11, 2026 -- Rising electricity prices are pushing German housing cooperatives to convert unused rooftop space into on-site solar power supply for members, a shift that can simultaneously cut resident energy costs and strengthen property economics.

Cooperatives hold both the roof and the resident relationship

Housing cooperatives occupy a unique position in the solar market: they own the building's roof and represent the interests of the people living beneath it. That dual role lets them install photovoltaic systems and sell the power directly to residents through tenant-electricity models, without residents needing to make their own capital investment.
