Generation of Electrical Power Using Solar Energy and to Design Simple Inverter Circuit with Large Power Output

Energy is the primary and most universal measure of all kinds of work by human beings and nature. Everything what happens in the world is the expression of flow of energy in one of its forms. Among different types of energies electrical energy is most important, because every individual is dependent on electrical energy for the every days life. It is clean and very convenient and can be transformed from one place to another easily. Today every country is meeting its energy demand by drawing power from a variety of sources. We can broadly categorize these sources as renewable and nonrenewable sources. The renewable sources include solar energy, wind energy, biomass energy, geothermal energy, tidal energy etc. The non-renewable energy sources include fossil fuels (coal, oil, natural gas), nuclear power. While the non-renewable energy sources will get exhausted eventually in the next century. Therefore we are going for the renewable sources because they do not exhaust, they can be used for long time, freely available from nature, does not affect environment. In recent years, the interest in solar energy has risen due to surging oil prices and environmental concern. In many remote or underdeveloped areas, direct access to an electric grid is not easily possible and therefore photovoltaic inverter system which works on solar energy would make life much simpler and more convenient. With this in mind, this project aims to design, build solar panel inverter. This inverter system could be used as a back- up during power outages, for battery charging and for typical household applications.
