Quality and good service are our first priority. As a result, the TÜV SÜD endorsed both and certified us to ISO 9001. For our web shop we have received the "TÜV S@fer Shopping" seal, which guarantees you secure shopping in our web shop, tested according to strict quality standards. Of course, the good and trustful cooperation with you across all channels is particularly important to us: For the thirteenth time in a row, the renowed maket research institute EuPD Research placed us amongst the best wholesalers in Germany – we recieved the seal „TOP PV-Supplier“.
