With vertically integrated West Coast factories capable of producing 500MW of panels annually, SolarWorld is a top US PV manufacturer. It has previously produced only monocrystalline solar silicon, wafers, cells and panels, in Hillsboro, Oregon, and Camarillo, California.

The addition of US-made 230- and 240-watt polycrystalline panels gives SolarWorld customers a wider array of choices that comply with the Buy American Act.
