ProductsPremium Quality Guaranteed
Made in Germany – GmbH
The cell type of a module is not always about the quality. Experience shows that there are both very good poly-crystalline and mono-crystalline cells, as less good products are also in both cell types. We offer only high-yield solar modules imported from Germany regardless of what type of cell is used.
As a manufacturer of Premium quality Premium modules, technological competence and innovation are deeply embedded in our philosophy.We operate a state-of-the-art production plant in Freiburg im Breisgau with a capacity of 210 MW p.a. and the possibility for further expansion. Full automation and meticulous inspections along the entire production process ensure the consistently high quality and longevity of our products.Since 2003,the quality- and environmental management of Solar-Fabrik has been certified according to DIN ISO 9001 and 14001. The energy used for production is obtained from renewable resources.More Info
