SOLAR TRACKING SYSTEM
INTRODUCTION:
In present situation everyone is facing the problem with power cuts which is creating very much trouble to the people. So, to solve this problem we have a solution that is sun. Yes by using sun radiation we can get power i.e., the solar energy using which we generate the power. All we are know that there are so many renewable energy sources like solar, wind, geothermal etc. but solar energy system is very simple and easy to implement. But the main drawback of the solar system is it is very poor efficient system. By using this project we are going to improve the efficiency of solar system.
Solar Panels are a form of active solar power, a term that describes how solar panels make use of the sun's energy: solar panels harvest sunlight and actively convert it to electricity. Solar Cells, or photovoltaic cells, are arranged in a grid-like pattern on the surface of the solar panel. Solar panels are typically constructed with crystalline silicon, which is used in other industries (such as the microprocessor industry), and the more expensive gallium arsenide, which is produced exclusively for use in photovoltaic (solar) cells.
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect.
