Photovoltaic material or PVs are necessary to change solar radiation into DC electricity. Many materials are used to make up a photovoltaic cell. Demand has dictated the production of cells, which has increased since 2002. Renewable energy demand has increased production even more than that in the past couple years. The following will discuss PV solar the energy for the future.
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.
Photovoltaics are created by using many different types of materials. Different types include but are not limited to cadmium telluride, copper indium selenide, polycrystalline silicon, etc. Polycrystalline silicon is one major contributor to the solar panel. By 2006, half the supply in the world was being used for creation of the solar panel. There were only twelve factories in production of the material in 2008.
Since the beginning of 2002, production of photovoltaics has increased by over twenty percent yearly. It is one of the most rapidly growing forms of energy technology in all of the world. At the end of 2009, installed installations of photovoltaics were over twenty-one thousand megawatts.
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.
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.
Do not close your mind to the idea of solar power, for fear of the sun not always being there. Scientists can predict with accuracy when it will and will not appear for the most part. Back up forms of energy can be used for days when it is raining or cloudy. There are plants that provide electric power operating on these principles currently.
