Solar Power is a natural source of energy and environmental friendly. The challenge of global warming can be deal with this natural source of energy. The Energy that derived from natural resources like Wind, rain, sunlight, heat etc. is known as renewable energy. This energy never ends and uninterruptedly filled again.
Renewable energy is significant because the other type of non-renewable energy like diesel, petrol, and fossil fuels etc. are limited. The large amount of renewable energy is basically comes from the sun. There are various types of renewable energy such as bioenergy, geothermal energy, hydropower, hybrid, ocean energy, solar energy, wind energy etc. but solar is the largest form of renewable energy source.
Solar energy is genesis for all forms of energy. This energy can be made use of in two ways the Thermal route i.e. using heat for drying, heating, cooking or generation of electricity or through the Photovoltaic route which converts solar energy in to electricity that can be used for a myriad purpose such as lighting, pumping and generation of electricity. With its pollution free nature, virtually inexhaustible supply and global distribution- solar energy is very attractive energy resource.
Solar cells, also called photovoltaic (PV) cells by scientists, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect. Solar cells were being used to power space satellites and smaller items like calculators and watches. Today, thousands of people power their homes and businesses with individual solar PV systems. Utility companies are also using PV technology for large power stations. Solar panels used to power homes and businesses are typically made from solar cells combined into modules that hold about 40 cells. The panels are mounted at a fixed angle facing south, or they can be mounted on a tracking device that follows the sun, allowing them to capture the most sunlight. Many solar panels combined together to create one system is called a solar array. For large electric utility or industrial applications, hundreds of solar arrays are interconnected to form a large utility-scale PV system.
