In order to convert solar radiation to direct current electricity, it requires the use of PVs, or photovoltaic material. Many different types of material are combined to create the photovoltaic cell. Due to the most recent demand for renewable energy, the manufacture of these cells has dramatically increased. There production has been steadily increasing since 2002 each year. Read on and find out how PV solar is one way to conserve natural resources in the future.
Photovoltaics create solar power by using solar cells to convert the energy from the sun into electricity that we can use. They do this by the process of photovoltaic effect. This effect explains that photons of light roughly moving electrons into an higher state of energy that will then create the electricity. An inverter is necessary to convert the direct current (DC) electricity to alternating (AC) 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).
Installing solar panels is being supported by many different countries. The governments of different countries are actually offering citizens and businesses alike different incentive packages to install them. New technology, and less expensive ways to manufacture have made the prices come down to a more affordable rate for everyone.
In 2008, it was said that solar power could provide one thousand times what the world would need and it only provide two tenths of a percent that year. By these statistics, it is apparent that renewable energy resources have not been used to the fullest; not even close. The prediction is that it will continue to double every two to three years. It could become the main power source for the world.
Some would say that solar power is not predictable, however, they are able to predict with exceptional accuracy when it will and will not be available. Other sources of renewable energy can also be used in conjunction with the photovoltaics. This has been proven successful in large power plants.
