Santa Barbara Solar Panels for Your Home
Solar panels are made up of arrays of ten to twenty photovoltaic cells which produce direct current electricity. These panels are usually placed on the roof of your structure but can instead be set up on the ground out of the way. Photovoltaic cells are made from several materials including monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium selenide/sulfide. Sunlight passing through thin membranes of these materials produces an electric charge which can be captured and used or stored.
Many variables go into calculating your electricity needs and the cost of a solar energy system for your home. There are calculators available on-line but also many professional companies like Verengo Solar that can do that for you. Electricity costs vary across the United States; for example, using 2008 figures, you would have paid a low of seven cents per kilowatt hour in West Virginia up to twenty four cents per kilowatt hour in Hawaii. For discussion purposes though, let’s take the average house in the United States which uses 1,000 kilowatt hours of electricity per month at an average price of twelve cents per kilowatt hour for a monthly electric bill of $120.
Conservatively, a solar panel will generate ten watts per square foot which translates to a typical 12% conversion efficiency of sunlight to electricity. Thus, for every kilowatt you would need to produce, you would need one hundred square feet of solar panels. However, since the sun only shines for part of the day and is affected by any cloud cover, the average house would need five hundred square feet of solar panels to generate enough electricity to meet the power requirements of the home.
Keep in mind that solar panel systems can last up to one hundred years with a minimal annual performance loss of one half of one per cent per year, and once installed these systems need very little maintenance.
