Energy From Sun

[Monroe]

The energy from Sun can empower the whole world for a long period of time. The usage of solar energy produces no pollution and is therefore environment friendly. Sun’s energy can be tapped by collecting its heat or by collecting its light and converting it into electricity. The sun’s radiation can be converted into electricity by using the solar power plants or photovoltaic devices, also known as Solar Cells.

In solar power plant, mirrors are used to reflect the heat energy from a large area onto a small space, such as a pipe filled with a fluid. As the fluid's temperature gets raised to hundreds of degrees, it is used to boil water and produce steam for a conventional generator. PV or Solar cells, on the other hand, change sunlight directly into electricity. A PV cell is a non-mechanical device usually made from silicon alloys that absorb photons emitted from the sun. The photons hit the silicon atoms in the PV cells, transferring their energy and releasing the electrons from their orbit around the nucleus, thereby generating electricity.

The promise shown by the solar energy technology has made investments into solar sector, worthwhile. It is a growing industry with increasing demand and better production capability. All this indicate that it is wise to make solar power investments.
