For 30 years, the Solarspar association has been financing, building, and operating solar power systems for agriculture, commerce, residential buildings, and the public sector. We seek the optimal solution for every project. We invest specifically in research projects for new applications in photovoltaics. We use donations to support solar projects and training in the field of solar energy in developing and emerging countries.

Photovoltaic general contractor

We invest – you benefit

Produce your own energy. You will find us to be a competent partner. We plan with you. We build, operate, and finance your photovoltaic system. You purchase the clean electricity directly for your own consumption, and Solarspar sells the surplus for you. We invest, you benefit.

Energy consulting

For our members: Get advice from us

Climate protection and the energy transition are important to us. That's why we are happy to support our members in planning their own photovoltaic systems.

Are you thinking about producing your own safe and clean electricity from the sun—on your own roof, no less?

Research

From utopia to reality

Solarspar works with expert partners to find and develop new solutions for using solar energy. When nothing off-the-shelf is available, we try out new things—such as using modified mowing robots on a PV green roof.

Obtaining solar power

Clean and independent

Regardless of your energy supplier, you can switch to pure solar power with us at any time. Every kilowatt hour of electricity from the sun replaces nuclear or coal-fired power. We make the switch to clean energy easy.
