The Solar power energy

Satisfactory Essays
A Photovoltaic cell also known as PV cell is a special kind semiconductor device that converts the solar energy into electrical energy. During the process, the photons from the sunlight are captured by the semi-conductor material. The captured electrons are then used to produce energy in the form of electricity. The first practical solar cell was created by Bell Laboratories in 1954, it only produced 1 watt of energy and the cost to produce 1 watt of energy was $250. The photovoltaic cell has enabled the use of the renewable energy source leaving no carbon footprint in the environment. The conventional energy is produced by various methods such as thermal power, hydroelectricity, nuclear power, geo thermal and hydrogen fuel cells. But they are costlier than PV energy and produce pollution. The Photovoltaic power generation in the solar panels uses a large number of solar cells. There are wide ranges of material available for the production to make the solar cell. The present available materials includes monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. Copper solar cables connect modules (module cable), arrays (array cable), and sub-fields. Because of the growing demand for renewable energy sources, the manufacturing of solar cells and photovoltaic arrays has advanced considerably in recent years. The first practical application of photovoltaic cell is to power orbiting satellites and other spacecraft. Another great example of the PV module is on the grids to connect with the power generation. In this case, an inverter is required to convert the Direct current to and alternate current. The cells that are mounted on a grid require protection from t... ... middle of paper ... ...r to the nation 2011 which is three times larger than Chinese Golmund Solar Park. The solar park is expected to save around 8 million tones carbon dioxide every year. Moreover, it will also save about 900,000 tones of the natural gas per year. The initial cost of power will be USD 0.29 per kWh for the first 12 years and after that it will lower to USD 0.10 per kWh. The electricity generated from the projects will be sold to the electric company and will be than distributed for household and commercial industries. In conclusion, the achievement is not merely a step in the direction of power conservation, but it also provides a vision to the world that how the power needs for the future generation can be solved in an environmental friendly way. The stand-alone solar project can benefit the environment and reduce the global warming. You can save green by going green!
