Photovoltaic energy

Photovoltaic is the method used to convert sunlight radiations into electricity. It uses semiconductors as exhibitors to exhibit Photovoltaic effects and to produce required voltage and current to perform different functions. These power systems need arrays, assemblies and number of cells in parallel and non parallel connections or diffusion of various solar cells with Photovoltaic material.

The material is of various types:

• Mono-crystalline silicon

• Polycrystalline silicon

• Amorphous silicon,

• Cadmium telluride,

• Copper indium solenoid

• Sulfide

Now, the demand for renewable energy is increasing day by day and now developing countries are also planning to introduce this type of energy to promote the domestic industries and cut down the expenses individual levels. German has installed power plants to promote the industrial production as well as to cut down the irrelevant wastage of resources which can be used in other forms for the betterment of people.

It is the fastest growing renewable energy production and power generation technology in the world as it has the double triple power than the other renewable resources available in the universe. It is the largest and valid source of energy with fewer side effects. More than 100 countries have already adopted this renewable energy as its small fraction 4800 GW is more than all energy resources present in the earth and atmosphere.

Building Integrated Photovoltaic is being used in roof or walls of the buildings and other installations may be ground mounted to promote and expand agricultural farming and grazing. Off-grid Photovoltaic installations are being used to get more power to perform industrial functions in no time.

Cost of production is less if we use renewable solar energy and Photovoltaic has given the signals for the same advantages. Production of first solar cell has given rise to open horizons for the new experiments and inventions which not only promote our life styles but will lessened the cost and financial worries in all individual, commercial and industrial levels. These are the reasons that every developed and developing country is on the way to get renewable energy resource to meet the need of hour.

There are three types of photovoltaic panels used to capture sun radiations and then convert them into required power forms:

• Mono-crystalline

• Polycrystalline

• Amorphous

The best advantage of solar power is that, it gives pollution free power. Waste material and emissions can be controlled after production using pollution controller equipment. Recycling technology can be enhanced after this. Photovoltaic installations get time in initial stage, afterwards it need maintenance but after a certain time period. Operating costs are much less than installation of other power plants to perform the same functions.
