Solar energy is something that we have really been looking into in recent years, if for no other reason than to try and find a better way to deal with getting energy without hurting the environment. If you don’t know a lot about solar energy, it is basically energy that we get from the sun that we convert into energy that we can use, whether that energy is used for electricity or for heating/cooling.
Solar energy simply means energy that comes from the sun. Sun is a powerful source of energy. Without it, there would have been no life on the Earth. It is renewable, free, widely available and clean form of energy that is currently in use by many home and business owners for variety of purposes.
Solar panels converts the sun's light in to usable solar energy using N-type and P-type semiconductor material. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photo voltaic (PV) effect. Currently solar panels convert most of the visible light spectrum and about half of the ultraviolet and infrared light spectrum to usable solar energy.
Solar energy technologies use the sun's energy and light to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry.
