Alternative Energy Technologies

Photovoltaic

Photovoltaic cells and arrays, also known as solar panels, convert sunlight into electrical energy. Now being used in a number of building applications, including shingles and fenestration, photovoltaics are becoming a common onsite renewable energy source. Whether roof-mounted or built into the design, solar cells are connected in series to achieve proper voltages. The energy produced can either be stored in batteries or tied directly to the municipal grid. In some cases, you may qualify for tax credits or rebates when purchasing and installing photovoltaic panels. You also may be able to sell the extra energy you produce back to your local utility.
