Because SolarWorld produces the highest quality, we can guarantee the best performance. That's why SolarWorld is the first solar company to offer a 25-year linear performance guarantee* for all modules installed after January 1, 2010.
According to our guarantee, the actual power of a new module cannot deviate from the specified rated power by more than 3% during the first year; and afterward, the power will not decrease by more than 0.7 percent of the rated power per year. So at year 10, the Sunmodule’s capacity is guaranteed to be at least 90% of the nameplate as opposed to the industry standard guarantee of 80%. This is added value that can help you get your project financed.
