Solar Electric (PV) technology uses sunlight to produce electricity. Individual solar cells, each made from semiconductor materials, connect together to form solar electric modules and produce electricity. These solar modules, in turn, combine and connect to form solar electric arrays.
Solar Thermal (Hot Water) Technology
Solar thermal technology uses the sun's energy to heat water. A typical system consists of roof-mounted solar collectors, which heat water to a certain temperature. The hot water is then stored in your home's existing electric hot water tank, ready for you to use.
