American-made SolarWorld modules ranked number one in two tests carried out by the Photon trade magazine back in 2008 and 2009. They generated 12 percent more power than competing brands. And they just keep getting better. The efficiency on the Sunmodule Plus SW 280-watt solar panel is up to 16.7% and its power tolerance is 0/+2%. This particular model has a matte silver frame and is made of mono-crystalline silicon cells, which many consider to be more desirable. Read about the differences
The SW 280-watt Sunmodule Plus is designed for long-term use, durability and ease of use. It will sustain loads of up to 113 pounds per square foot, which means it will withstand even the harshest weather conditions. Its Version 2.5 frame is compatible with “Top-Down” and “Bottom” mounting methods.
SolarWorld products are manufactured in state-of-the-art factories according to US and international labor and environmental standards. Their flash testing process ensures that any SolarWorld solar panel delivered to your door has greater than or equal power to the nameplate rated power.
SolarWorld’s solar panel warranty is different than many of its competitors. Their linear warranty guarantees that the power generated will not decrease more than 0.7% per year from its nameplate over a 25-year period. The SW280 Sunmodule Plus also comes with a 10-year product warranty.
