American solar panel brands include SunEdison, First Solar, GreenBrilliance USA, Renogy and Trans-Pacific Energy. Solar panels harvest the sun's energy and convert it into electricity.
Based in Maryland Heights, Missouri and Belmont, California, SunEdison manufactures high-purity monocrystalline and polycrystalline silicon ingots, wafers, solar modules, solar energy systems, and solar module rack systems. As of 2015, its most recent projects are installation of a 2-megawatt solar power plant for the town of Elkton, Maryland, as well as a 1.2-megawatt solar facility for the Metropolitan Council of the Twin Cities in Minnesota. SunEdison is one of the country's biggest solar companies, providing solar energy solutions to homes, businesses, utilities and the public sector.
Headquartered in Tempe, Arizona, First Solar manufactures rigid thin-film solar panels made of cadmium telluride as a semiconductor instead of conventional crystalline silicon. The company's solar panels operate at about 14 percent efficiency at a cost of 59 cents per watt, as of 2013, which approaches grid parity. As of 2012, First Solar has installed 1,505 megawatts of solar capacity worldwide. Its largest projects in the United states are in California, Arizona and Nevada.
