SolarWorld modules ranked number one in two tests carried out by the Photon trade magazine in 2008 and 2009. They generated 12 percent more power than their competing modules, and they just keep getting better and better. The efficiency on the Sunmodule SW 250-watt solar panel is up to 14.91% and its power tolerance -0/+1.96%.

The SW 250-watt Sunmodule is also built for long-term use, stability and ease of use. It will sustain loads of up to 113 pounds per square foot, whether it's snow or wind.

SolarWorld products are manufactured in state-of-the-art factories according to US and international labor and environmental standards. Their flash testing ensures that any SolarWorld solar panel delivered to your door has greater than or equal power to the nameplate rated power.
