Photovoltaic
Ipsum lorem ad sea, in reque bonorum definiebas mei IusThe sun can produce approximately 1,000 watts of energy per square meter of the earth’s surface on a completely sunny day, which can be used to power our homes and businesses for free. Solar power is commonly related to solar energy and vice versa, and even to refer to the conversion of the sun’s rays to electricity (via photovoltaic effect).
A solar cell or a photovoltaic cell is a device that converts sunlight into electricity through the photoelectric effect. Solar cells are made with semiconductor materials that are generally used in the microelectronics industry, especially with silicone. In solar cells, a small semiconductor wafer is specially treated to form an electric field (1 positive and 1 negative). When the energy of the light hits the solar cell, the electrons leave the atoms that are in the semiconductor material and by using the electrical conductors located at both ends, an electrical circuit is created where the electrons are captured to generate electricity.
The use of photovoltaic cells and panels is one of the most used methods to generate electricity using energy from the sun.
The number of solar cells that are electrically connected with the others and mounted in a frame are called a photovoltaic module, which have 300 watts each and by combining them, we can get the desired amount of electricity to meet our domestic and commercial needs.
These photovoltaic modules can be connected in both series and in parallel to produce the voltage and current necessary for our needs. Although the current made by the modules is Direct Current (DC), the system has a converter that transforms it to Alternating Current (AC) and that way, it can work without problem.
With today’s manufacturing technology, we can achieve 35% efficiency in converting solar energy to electricity.
