Get all the watts you pay for
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.

Proven superior reliability multiplies the SolarWorld performance advantage
Most solar PV companies have only been around for a few years and can only speculate how their products will perform long-term. With over 35 years of solar panel manufacturing experience, SolarWorld has had solar panels in the field for the entire warranty period. Independently monitored data from multiple megawatt-scale systems installed over 25 years ago confirms that our modules continue to outperform for decades.

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 3, the Sunmodule’s capacity is guaranteed to be at least 95.6% of the nameplate as opposed to the industry standard guarantee of 90%. And at year 20, it’s still at least 83% as opposed to the industry standard 80%. SolarWorld’s linear performance guarantee provides clear added value that you can take to the bank.

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.
