Solar Power Generation
Solar Power • Solar power generation is the simply the generating the energy from sun. • Solar energy is the mechanism of generation of solar energy with the help of technology used to trap the sun’s energy and make it usable for other purposes. • Sun emit the energy in the form of electromagnetic radiation and this energy is converted into the thermal or electrical energy on earth.
Photovoltaic Cells • Photovoltaic cells are also knows as solar panels. • It is usually installed on the rooftops. • Photovoltaic cells are made up of semiconductor materials like monocrystalline silicon, polycrystalline silicon, copper indium sulfide, etc. • When sunlight falls on the cells, electrons become loose and they flow through the cell and generate electricity.
Solar Power Plants • Solar power plants implement the variety of techniques to generate the solar energy as a source of heat. • This heat energy is used to run the turbine and boil water to generate the electricity. • This generated electricity is supply to the residential and commercial areas.

Solar Power for Homes • Solar power panels are mounted on the rooftop to generate the solar power for homes. • To keep the building warm at night, big windows are installed on the direction of sun to consume the sunrays on the absorbent materials present on the floor and walls.
Solar Energy • Solar energy is the inexhaustible source of energy. • Solar energy is noise and pollution free. • Solar energy can also be generated in the night with the help of photo switching. • Solar technologies are costly but, they give good return on investment within a few years. • Many countries including Japan, US, India are investing in solar energy generation.
