Santa Barbara Residential Solar Power
Photovoltaic cells power homes by directly converting sunlight into electricity. One common argument against relying on solar energy for electricity is that the sun only shines during the day, and depending where you live, it does not shine 365 days a year. Rechargeable batteries are used to store excess electricity generated during the day for use at night. Another way to provide electricity at night is called net metering which basically uses the utility company’s grid as an electricity storage vehicle. In net metering, a homeowner sells any excess electricity generated by day to the transmission company’s grid. This establishes a credit for the homeowner which will offset any demand for electricity from the grid at those times when the solar energy system cannot provide the needed electricity.
Created in 1954 by Bell Labs, photovoltaic (PV) cells were initially used to power satellites in outer space. Today, businesses and homes are powered by individual photovoltaic cell systems. The average house will use a group of ten to twenty solar panels called an array, to provide electric power. Each solar panel is comprised of individual modules that hold forty cells each and are then mounted in one of two ways. They can be mounted facing constantly south, or they can be attached to a track which would permit them to follow the sun which allows the panels to collect the maximum amount of solar energy. Electric utility companies and large industrial users of electricity create large electric generating systems by interconnecting hundreds of solar arrays.
The basic photovoltaic cell is made of flat-plate silicon and is considered the most efficient. Newer cell technologies include so-called thin film solar cells which are made from silicon or non-silicon materials in layers only a few micrometers thick. These thin film cells are very flexible which allows them to also be used as roofing shingles, building facades, or glazing for skylights.
