How Do Solar Plant Works
Solar power is a renewable energy source that uses the sun’s rays to produce electricity. Solar panels use photovoltaic cells to convert sunlight directly into electricity using a process called photoelectric effect. These devices consist of two layers of silicon wafers coated with different materials. When light hits the first layer (the front side), some of the photons are absorbed and create electron-hole pairs. As the electrons and holes move across the junction between the two layers, they generate an electric current. This current can then be collected and converted back into usable electricity.
How Do Solar Panel Works
– Solar panels convert sunlight directly into electricity using photovoltaic cells. These cells are composed of two layers of semi-conducting materials called p-type and n-type semiconductors. When exposed to light, electrons move from the valence band to the conduction band. In the case of silicon, the electron movement creates a voltage potential difference across the material. This potential difference causes current to flow.
– Solar panels are mounted on a frame and placed over a desired area where they collect sunlight. The amount of power produced by the panel is determined by the size of the panel, its orientation, and how much sunlight it receives.
– There are three basic types of solar panels: monocrystalline, polycrystalline, and amorphous. Monocrystalline panels have fewer defects than polycrystalline panels and produce higher quality electricity. Amorphous panels are cheaper than both monocrystalline and polycrystalline panels.
– Solar panels require no maintenance once installed. If properly maintained, they can operate for 20 years or more.
– Solar panels generate DC electricity. To connect them to the grid, they need to be converted to AC electricity. This is done by inverters.
– Solar panels are generally mounted on rooftops or other flat surfaces.
