POWERMAX® 3.5: PREMIUM CLASS PHOTOVOLTAICS

Our successful flagship is the brand PowerMax®. PowerMax® modules offer a high energy yield (kWh per kWp), possible due to broad spectral sensitivity, proven low-light-performance, a low temperature sensitivity as well as an excellent tolerance against partial shadowing.

The latest product generation, PowerMax® 3.5, not only meets the highest technical requirements, it is also the most economic and aesthetic one on the market. An innovative CIS product design and a fully integrated industrial production process provide the basis of this success.

As an integral part of the production line, more than 140 quality and process monitoring check points guarantee consistent performance. Our production is certified according to all relevant industry standards.

Rely on quality: modules designed and made in Germany. 
Find out more and become part of the bright future of CIS photovoltaics!
