The Solarspar association has been financing, building and operating solar systems for agriculture, industry, residential buildings and the public sector for 30 years. We look for the optimum 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 a competent partner in us. We plan with you. We build, operate and finance your photovoltaic system. You purchase the clean electricity directly for your own consumption, Solarspar sells the surplus for you. We invest, you benefit.

Energy advice

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 system. 

Are you thinking about producing your electricity safely and cleanly from the sun - and on your own roof? 

Research

From utopia to reality

Solarspar searches for and develops new solutions in the application of solar energy together with competent partners. Where nothing prefabricated is available, we try out new things - such as the use of adapted mowing robots on a PV green roof.

Purchase solar power

Clean and independent

Independent 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.
