Solar energy is the term given to the radiant light and heat from the sun. The sun, being the biggest source of energy, is the purest source of renewable energy available to the whole world. Not only that but it is eco friendly process of obtaining cheap energy and producing cheap energy in general.
Solar energy production is the process of capturing the radiation from the sun and converting it into usable electricity. In more technical terms the solar photovoltaic system produces alternative current (AC) which needs to be converted into direct current (DC) or electricity that you can use, thus the need of an inverter. The generation of solar energy is created by the usage of solar photovoltaics panels or as they are called solar PV panels. Solar photovoltaics are made mainly from silicon, which is one of the most abundant materials on earth. They are made from either monocrystalline or polycrystalline silicon and that is why the modules are separated in monocrystalline and polycrystalline modules.
Put simply, Photovoltaics, or PV, are electrical devices that convert light into DC electricity. The light can be from any source. As long as the light is the right colour (white light is all colours) some electricity will be produced from a solar cell. The more intense the light, the more electricity is produced. Each cell produces only a small amount of power, but when the cells are strung together in series to make solar modules they become more useful. A solar module can then be installed with other modules to form an array. The total energy output can be quite substantial.
A solar cell is a semiconductor diode that when stimulated with light, produces an electron and a positive charge on opposite sides of the cell. Wires collect the charge off each side of the cell and take this electricity to the load circuit, such as a light bulb. Wiring cells in series increases the voltage, and in parallel increases the current output. For the cells to be useful, they must be put together in a system with other components sometimes called a 'photovoltaic system' or a 'solar energy system' or a 'solar electric system' or a 'solar PV system'
