When you harness the wind, you are using a free, renewable energy source that will reduce the amount of electricity you purchase. Because it is renewable and non-polluting, it helps to protect the environment, increases energy self-sufficiency, and can help protect you from future electricity price increases.
Solar photovoltaic (PV) technology, uses sunlight to produce electricity. Individual solar cells, each made from semiconductor materials, connect together to form PV modules and produce electricity. These solar modules, in turn, combine and connect to form PV arrays.
