Where Does Active Solar Energy Come From

Solar hot water systems use pumps or fans to circulate fluid often a mixture of water and glycol to prevent freezing during winter periods or air through solar collectors and are therefore classified under active solar technology.

Where does active solar energy come from.

Active solar energy is the conversion of solar energy into usable heat via electrical or mechanical equipment such as pumps and fans which increase the usable heat in the system. Active solar systems rely on pumps sophisticated electronic devices and motors to effectively collect and systematically provide solar energy. There are different ways of capturing solar radiation and converting it into usable energy. Humans can capture solar energy directly from the sun through passive and active solar energy systems ancient people used passive solar energy systems by building their houses out of stone or clay which absorbed the sun s heat during the day and stayed warm after dark providing heat throughout the night.

Active solar systems use solar collectors and additional electricity to power pumps or fans to redistribute the sun s energy. A passive solar home converts solar energy into heat just as a closed car does. To control the amount of heat in a passive solar house the doors and windows are closed or opened to keep heated air in or to let it out. The total amount of solar energy incident on earth is vastly in excess of the world s energy requirements and could satisfy all future energy needs if suitably harnessed.

Solar energy is sunshine. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. It also does not need power coming from an external conventional source. Active solar heating systems are most cost effective in cold climates with good solar resources when they are displacing the more expensive heating fuels such as electricity propane and oil.

Solar energy radiation from the sun capable of producing heat causing chemical reactions or generating electricity. The methods use either active solar energy or passive solar energy. Sunshine is radiant energy from the sun. Passive solar energy does not require mechanical equipment and electronic devices to gather and distribute solar energy.

Some states offer sales tax exemptions income tax credits or deductions and property tax exemptions or deductions for solar energy systems. Sunlight passes through a home s windows and is absorbed in the walls and floors. Active solar technologies use electrical or mechanical devices to actively convert solar energy into another form of energy most often heat or electricity. Passive solar technologies do.
