All Solarworld modules come with extended 20 years product warranty for modules installed from 01/01/2017.
SolarWorld quality standards go far beyond the norm. SolarWorld applies these high standards for product quality at all its production sites. SolarWorld specifications, quality guidelines and tests, and defined quality materials are the same throughout the world. The TUV Rheinland Power controlled inspection mark guarantees that the nominal power indicated for solar modules is inspected at regular intervals and thus ensured. The deviation to TUV is maximum 2 percent. The positive power tolerance guarantees utmost system efficiency. Only modules achieving or exceeding the designated nominal power in performance tests are dispatched. The power tolerance ranges between -0 Wp and +5 Wp. With its linear performance warranty covering a period of 25 years, SolarWorld guarantees a maximum performance degression of 0.7% p.a., a significant added value compared to the two-phase warranties common in the industry. Therefore, the service certificate offers comprehensive protection for your investment in the long term.
