Photovoltaic devices use semiconducting materials to convert sunlight directly into electricity. Solar radiation which is nearly constant outside the Earth's atmosphere varies with changing atmospheric conditions (clouds and dust) and the changing position of the Earth relative to the sun. Nevertheless, almost all U.S. regions have useful solar resources that can be accessed.
