Concentrating solar collectors use mirrors and lenses to con-centrate and focus sunlight onto a thermal receiver, similar to a boiler tube. The receiver absorbs and converts sun-light into heat. The heat is then transported to a steam generator or engine where it is converted. . Electric utility companies are using mirrors to concentrate heat from the sun to produce environmentally friendly electricity for cities, especially in the southwestern United States. There are three main types of mirrors used in solar energy systems: parabolic mirrors, flat mirrors, and heliostats. In contrast, heliostats — which get their name from Helios, the Greek god of the sun — look like traditional solar panels but are actually. . Rooftop solar panels are a familiar sight but are not the only way the sun is used to create energy.
