PV or photovoltaic material is what is used for the conversion of solar radiation to direct current (DC) electricity. There are several different types of materials that are used to make up the cell. The manufacturing of cells has been increasing since 2002, and continues to grow because of an even larger demand for renewable energy in the past couple of years. Continue reading and find out how PV solar is one of the most abundant forms of renewable energy.

To change the radiation that we get from the sun into electricity, photovoltaics use solar cells. The photovoltaic effect is a process that explains how photons of light force movement of electrons until they are charged and electricity is created. The electricity that is created initially is direct current, and to use it in most instances, it is converted with an inverter to alternating current.

Many materials are used to create photovoltaics. Some of the materials include different types of silicons, copper indium selenide, and cadmium telluride. Polycrystalline silicon is a key material of a solar panel. The supply of solar panels that can be created is limited to the supply of polycrystalline silicon, and in 2006, half of the supply in world was in use for solar panels. There were twelve known factories that were producing the material in 2008.

The production of PVs has increased by at least twenty percent per year beginning in 2002. That labels it as the fastest growing energy technology in the world. By the end of 2009, worldwide, installed PVs totaled more that 21,000 megawatts (megawatt=1 million watts).

Many countries are in supporting the installation of photovoltaics for residential and commercial use. In fact, many governments are promoting such use by offering incentives for their installation. Because of the technological advances, and the increase in the manufacturing, the prices have been driven down, and the products are much more affordable.

It was stated that in 2008, solar power was able to provide the world with up to a thousand time what they would need, and yet it only supplied two tenths of that. By those statistics, we are wasting valuable renewable energy every year. Current predictions state that those figures will double every couple of years. Solar energy could be the main source of power in the world.

Many would speak against the dependability of solar power, but science can predict with extreme accuracy when the sun will be in view. There are many other sources of renewable energy that can be used with solar power to compensate for cloudy days, etc. Large power plants are actually operating on these systems.
