Quality you can rely on.

SunClass solar modules meet the highest demands.

We make the highest demands on our products - of course only high-quality wafers are already used for production of SunClass solar cells. So, together with a stringent quality management, we set the course for highest possible quality in situ.

Our solar modules undergo regular inspections from the german Dependence and German employees of TÜV Rheinland at production sites in Asia - no solar module leaves the manufacturing facility without previous calibration as well as stress testing by independent experts .

But that is not all - in regular charging inspections SunClass solar modules are subjected to strict controls from Bremen test laboratory Adler Solar-Services since 2011.

In addition to visual testing, thermography tests, insulation tests, flash tests as well as electroluminescence tests are carried out by using newest high-tech testing methods. These provide a detailled test result and exclude smallest variations and errors.

The results of these tests - if needed - are of course reflected in the currect production of our solar modules. In this way, everyone benefits: Our customers, they can rely on independent quality seals with double safety and especially on our products, because these can be further improved during operation.
