Solar energy is one of the most available types of renewable energy. In order to use solar energy, radiation from the sun must be converted into electric power using photovoltaic cells. The process that makes this conversion is known as the photovoltaic effect. The following will discuss photovoltaics and the development of solar panels.
Solar technologies are generally characterized by the way in which the solar radiation is captured. There is passive solar, which refers to the conversion of sunlight to useful energy without the assistance of any type mechanical devices (solarium). Active solar refers to the conversion of sunlight by means of some type electrical or mechanical equipment. Photovoltaic cells can be used in both passive and active solar capture.
The photovoltaic effect is best described as a material being subjected to electromagnetic radiation. Voltage is created with the charged material. Alexandre-Edmond Becquerel was the first to notice this effect in 1839.
In one year, the amount of solar energy that falls to the surface of the earth is so enormous that it will surpass by double the amount of non-renewable energy sources of coal, oil, natural gas, and mined uranium on the earth. The levels of solar power that can be captured in the world are different, depending on the area that it is being captured in. Areas closer to the equator will capture more solar power.
Spacecraft and orbiting satellites were the first to use the photovoltaic cell. The cells are now used for many things including power. A cell module or a solar cell can produce a direct current, and to be used for residential and commercial use, it then needs to be converted to alternating current.
Photovoltaic cells or solar panels were expensive to install, but now, with new government incentive programs from various governments worldwide things have changed. Use of solar energy is being widely encouraged. The most recent events have shown that we need to be using solar power now more than we ever have before. Solar panels have also decreased in price just over a period of time in the past few years.
When the public was first able to view photovoltaic cells, it was in the form of the solar calculator and other small gadgets. Roadway lighting systems are now being tested in different parts of the United States. They can now be seen in different devices like parking meters and street lamps. Across the world, there are several power stations using solar power. The need for photovoltaic cells is growing with the ever increasing need for renewable energy.
