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.
Solar cells are what photovoltaics use to change the energy that comes from the sun into electrical energy. The process by which this is done is referred to as the photovoltaic effect. The effect describes the photons of light moving around electrons enough that they are placed in a state of energy higher than before, which then creates electricity. In order to convert the electricity that is created from direct current to alternating current, it is necessary to use an inverter.
Some materials used to make photovoltaics are monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium selenide. Polycrystalline is one key component of the solar panel, and panel creation is limited to the amount of its supply. In 2006, over half the supply in the world was being used for solar panels. In 2008, there were twelve factories producing polycrystalline.
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.
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.
