"Solar power" is the conversion of the abundant energy of sunlight into a form that can be used for purposes sunlight doesn't serve directly. The most common meaning of the term involves the conversion of sunlight into electric power, through the use of solar panels for your home normally, and that's what will be discussed here.
The amount of energy from the sun is enormous, and it flows continually in abundance whether we make use of it or not. Less than one part in 8,000 of the sunlight striking the Earth could supply all of the energy needs of the entire population of the planet. Domestic solar power is also free to use, inexhaustible, and non-
Solar roof panels are collections of photovoltaic cells that convert sunlight directly into electricity. Photovoltaic cells are constructed of semiconductors such as silicon (the most common material used). When sunlight strikes a semi conductive material such as silicon, a part of it is absorbed by the material, and the process of this absorption energizes electrons within the material, some of which are freed to flow as current.
Metal contacts placed at the ends of the photovoltaic cell allow the current to be
drawn off and conducted away for use. The result: solar power! A solar panel is made
of multiple solar cells that together generate a flow of power usable for various
purposes, such as to power a home. Solar panels are measured in wattage and also
in area or square inches of surface.
How much area of solar panel would be required to provide solar power for a typical house? That depends on how much power the home uses, which varies depending on the size of the home, the energy efficiency, and what type of appliances are in use. Continued below....
It also varies by where you live; a home in southern Arizona receives more dependable solar power than one in northern Minnesota.
A typical home that does not use electricity for heating or air conditioning and
is not particularly energy-
Of course, if someone were using solar power to partially reduce energy consumption from the grid rather than to achieve complete self-
A home solar power system can be designed either to be "on-
In either case, a battery is normally used to allow use of the system during times when the sun isn't shining.
