Uses of Solar Energy for Residential Purposes

Today's homes have vast energy requirements, whether for heating, cooling, lighting or another purpose. All these require electricity or energy.

The most common use of Solar Energy in residential houses is for the purpose of heating water. A solar panel can convert sunlight into heat. The bottom of solar panels is black so that they can absorb as much heat as possible. A glass-covered water pipe then coils up along the side of the solar panel. When it is sunny, the water in the pipe is heated and this hot water can then be stored in a tank underneath the house or somewhere else out of sight.

Another major and more common use for Solar Energy is the conversion of sunlight into electricity. Solar cells convert sunlight into electricity. These cells are usually made out of silicon which is common material found in sand. Electrons from silicon atoms are released when sunlight hits a solar cell, and these electrons flow away. Since electricity is actually the flow of electrons from one place to another, each solar cell produces a small amount of current or electricity.

Solar Energy is now used in a variety of ways. Calculators and watches often run on solar cells, and larger solar cells are used to provide power for solar cars.

Other areas where Solar Energy is being used are heating swimming pools, power for satellites in space, power for parking meters and street lights.
