Many times you have seen solar panels but, you really know how they produce the electricity that we consume in our homes. I will explain it to you below,
Photovoltaics, as a renewable energy source that produces electricity, does not have a negative impact on the environment. The principle of operation of photovoltaic panels is that the photovoltaic cells that make up the panels convert solar energy into electricity. To do this, a photon (that is, the minimum unit of light) strikes a silicon wafer, which is a photovoltaic cell.
How do solar panels and photovoltaic cells work?
The unit of light is absorbed by the silicon and knocks the electron out of position and forces it to move. This movement is the flow of electric current. Thanks to the use of a pn-type semiconductor junction, it is possible to connect this process with the circulation of electrons in the electrical network, thus transforming light energy into electricity.
Photovoltaic panels produce direct current, so to take advantage of the energy we need to install the inverter ( inverter ), which will change the current photovoltaic panels into alternating current (in reality, alternating). The photovoltaic installation is a good ecological solution due to the lack of carbon dioxide or sulfate emissions. It does not produce polluting exhaust gases. Investing in a photovoltaic installation eliminates problems with electricity bills. The use of a photovoltaic plant is completely free and durable.
