Low energy consumption of Electronic Devices

When certain solids came into contact with light, it frees negative and positive charges in the solids and creates electrical activity i.e. electricity in them. The famous scientist, Albert Einstein received the Nobel prize in physics for analyzing this phenomena which came to be known as ‘the Photoelectric Effect’.

The following section explains in brief, how this phenomena is implemented in solar panels for electricity generation. It is estimated that 30% of energy is used to heat water, which can be generated using solar panels. Solar panels for electricity generation can last up to 25 years and there is almost no expenditure in maintaining them.

Solar energy is a combination of heat and potential energy, that comes to the surface of the earth in the form of sun rays. When the sun rays or rather the radiation of the sun reaches the surface of the earth, in transforms itself into heat and light energy.

The heat and light energy, can be utilized by different techniques, to produce usable forms of energy. Many scientists have elaborated and emphasized the advantages of solar energy as a source of energy and a raw material for usable energy production. Some of the common solar energy appliances, that can be prominently used for domestic purposes.
