Rather than being just a supplier of collector components. ForSun Solartechnik has always worked together as partners with our clients, using innovation to seek solutions to your needs.


Projects developed with our clients can be comparison tested for performance using ForSun’s testing equipment. 

If you are seeking to reduce stagnation temperatures, reduce weight and size of collectors, avoid condensate or reduce costs, ForSun is with you every step of the way.


In 2015, the largest solar thermal absorber in Germany (surface area 120 m²) was built using ForSun’s CSW technology.  The experience gained with cutting edge projects like this, gives ForSun the lead in the development of future technology.
