Energy Efficient Solar Power Systems
Harnessing the power of the sun and converting it to energy we can use for our every day needs is achieved through several methods. The two most common are the Photovoltaic system or PV system, that converts sunlight directly into electricity and the Concentrating Solar Power, or CSP system, which uses the heat from the sun instead of fossil fuel, to provide the heat to fuel a traditional power plant.
A photovoltaic panel is the most well known of the solar power systems. Iit consists of solar panels with special semiconductor materials inside that generate electricity upon contact with sunlight, thereby creating solar power. Solar power produced in this manner is clean, with no environmental impact and is a renewable source of energy that will save you money in the long run.
PV solar power systems for the home produce energy that goes into a power inverter, which changes the electric current from direct to alternating current before being routed to the home. This makes the resulting power indistinguishable from the electricity that you would receive through conventional power generation from your local utility through your homes circuit breaker panel. After it travels through the inverter, the electricity may then be sent to power your appliances and lights, or else it may be sent to a power storage system, consisting of an array of batteries, which will ensure that you have power after sunset.
A properly installed PV solar power system can supply all of the power requirements of homes or buildings even in remote locations. Depending on the distance from the house to the existing electric grid, this may cost less than conventional electricity. Being many miles away from the nearest utility source in order to connect to the grid can cost more than installing a solar power system, with no way to recoup the investment.
The CSP or Concentrating Solar Power system is a solar power system that uses solar-thermal technology to generate electricity. An array of mirrors or panels collects the heat from sunlight and transfers the heat to a generator directly or through the circulation of heated fluid to the generator. The CSP system can supply the heat necessary to produce power in a traditional power plant, replacing the use of fossil fuels like coal.
Solar power systems can offer better economic savings to business and individual customers alike. Utilizing solar power as a supplemental source of energy can reduce the monthly electric bills or in the case where solar power is the sole source, eliminate the electric bills altogether.
While its certainly true that installing a solar power system is by no means cheap, its also true that the return on your investment can well justify the initial outlay. Think of it this way, other major home improvement projects such as kitchen remodeling may add value to your home, but they wont pay you back until after you sell the house at a profit.
