Without the sun, life as we know it would not exist. The light and heat radiated by the sun sustain plant and animal life on earth, providing the fuel for all of the planet's natural processes. Since humans walked the earth, we've used the sun in countless ways. In recent decades, we've discovered how to convert the sun's heat and light into clean, reliable sources of electricity. It is called Photovoltaics (PV), meaning "light electricity," is a diverse technology that converts the sun’s light directly into electricity. This electricity can provide power to your homes, businesses with the capability to meet a wide variety of electrical needs. To convert the freely available sun light into useable electricity number of electronic components are put together to make a Solar Power System.
