Better energy performance means more money in your pocket

It’s not the kW rating of your PV system but the number of kilowatt-hours of energy it generates which determines how much you save on your electric bill. Independent testing over multiple years proves that the SolarWorld Sunmodule®, the heart of every Sunkit, generates more energy than similarly rated modules from other major brands.

And because the entire system is designed at the factory, all of the components are optimized to work together for the highest possible performance.

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 30 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.
