SolarWorld - Sunmodule 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].

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.

Award-winning performance

Photon test results show SolarWorld SUnmodule panels produce more energyAs the largest solar manufacturer in America since 1977, SolarWorld applies over 3 decades of experience to continuously improve our products.

This attention to detail is evident when our customers call to tell us that their systems are outproducing model predictions year after year. It also shows up in independent testing like the ongoing module performance test conducted by Photon magazine [PDF 1MB] where SolarWorld panels outperformed all other major brands tested for the last 2 years in a row.

In addition to generating more energy, our Sunmodule® solar panels are also more durable and reliable than others and can withstand things like snow loads up to 113 pounds per square foot, high heat and humidity, even 1 inch hail stone impacts at up to 50 mph.
