Description of this Off grid Class A 280W monocrystalline solar panel photovoltaic power generation system
 
As global energy sources become more and more tense, solar energy has become a new type of energy and has been vigorously developed. Among them, solar panels are the most used in our lives.The solar panel is mainly made of semiconductor material silicon. After the photoelectric material absorbs light energy and photoelectric conversion occurs, so that it generates electric current, what is the working principle of the solar panel? The solar cell directly emits light through photoelectric effect or photochemical effect. A device that can be converted into electrical energy. When sunlight hits the semiconductor, a portion of it is reflected off the surface and the remainder is absorbed or transmitted by the semiconductor. Of the absorbed light, of course, some become heat, and other photons collide with the valence electrons that make up the semiconductor, thus generating electron-hole pairs. In this way, light energy is converted into electrical energy in the form of electron-hole pairs.
