Long-term performance
SolarWorld's linear warranty guarantees maximum performance from you solar panels.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 [PDF 176KB] and a 10-year product workmanship warranty.
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 sold or financed.
Get all the watts you pay for
SolarWorld's unique plus-sorting method ensures that our customers receive the watts they pay for from their solar panels.With plus sorting, SolarWorld only delivers modules that are factory-tested to meet or exceed their name plate power rating - even after initial light induced degradation. By delivering actual power, plus-sorting minimizes module mismatch losses and eliminates name plate tolerance losses, which can account for up to 5% in modeling programs like PVWatts and PVSyst.
Sunmodule™ solar panels are also independently tested to strict international standards for safety, durability.
Made in the USA
What does it really mean to be made in America? 
For SolarWorld, being made in America means more than simply assembling foreign components in the USA, which does little to benefit the economy. By carrying out the entire PV module value chain in the USA , we are creating American manufacturing jobs not only at our factories but at our suppliers’ factories as well.
SolarWorld is investing over $500 million to expand US-based manufacturing, which generates hundreds of millions of dollars each year for American workers, goods and services.
