Using the warmth of the sun and transforming it into fuel that will be used for our household needs can be done several ways. The two most popular ways are the Photovoltaic system also known as the PV system and the Concentrating Solar Power, also known as the CSP system. The PV system makes electricity using the light from the sun and the CSP system takes the heat from the sun to make fuel for a power plant.
The best-known solar power system is the photovoltaic system, made up of semiconducting material which, when exposed to sunlight, releases electrical power. Energy produced by PV solar power systems is renewable, environmentally-friendly and highly cost effective for long-term use. Once a system is installed, the power of the sun is all that is needed.
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 Concentrating Solar Power or CSP system utilizes what is known as solar-thermal technology. The CSP system uses an array of panels and mirrors that capture the heat from the sun and then transfer that heat either directly to a generator, or carried through fluids circulated through the panel system to a generator. The heat supplied by the CSP system is then used in place of coal or other fossil fuels to produce power on a large scale in a traditional power plant setting.
There are tremendous financial benefits for both homeowners and business when installing a solar power system. When installed as supplemental power, solar power reduces your monthly power costs, and when installed as the sole power source your monthly utility bill is eliminated.
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.
