Your partner in Cologne

and the surrounding area

for planning and implementation of your own

photovoltaic system!

Mit Solarstrom Energiekosten senken und
unabhängig von klassischen Energieträgern
eigenen Strom klimafreundlich produzieren!


"As an engineer for renewable energies, I am convinced that anthropogenic climate change can only be stopped by converting our entire energy system to renewable energy sources.

Photovoltaic systems in private as well as industrial format play an important role here. Moreover, no other technology can be implemented without additional sealing of surfaces. With their high levels of efficiency, long system lifetimes and moderate costs, they offer the ideal opportunity for everyone to actively participate in the energy transition. The technology is also financially feasible, like a bank investment with 3-6 % interest. Risks are basically non-existent and minimized through careful planning.

As a competent specialist partner, we want to actively and individually support our fellow citizens - because climate protection is a community thing and begins with ourselves. "

- Stephan Gerhards, owner and engineer for renewable energies
