	Solar power - Wikipedia, the free encyclopedia
		Energy obtained from methane (natural gas) may be derived from solar energy either as a biofuel or fossil fuel, but some methane derives from the primeval gas cloud which formed the Solar system and is therefore not solar in origin.
		Solar design is the use of architectural features to replace the use of grid electricity and fossil fuels with the use of solar energy and decrease the energy needed in a home or building with insulation and efficient lighting and appliances.
		Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and usually a reservoir to stock the heat for subsequent use.

		Solar energy is needed by green plants for the process of photosynthesis, which is the ultimate source of all food.
		Solar batteries, which operate on the principle that light falling on photosensitive substances causes a flow of electricity, play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth (see solar cell).
		Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container.

	Solar Energy
		The major drawbacks (problems, or issues to overcome) of solar energy are: (1) the intermittent and variable manner in which it arrives at the earth's surface and, (2) the large area required to collect it at a useful rate.
		Solar thermal power generation is essentially the same as conventional technologies except that in conventional technologies the energy source is from the stored energy in fossil fuels released by combustion.
		Energy losses from thermal-energy transport are minimized as solar energy is being directly transferred by reflection from the heliostats to a single receiver, rather than being moved through a transfer medium to one central location, as with parabolic troughs.
