Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert solar energy into electrical energy. Photovoltaic power generation systems are mainly composed of three parts: solar panels (components), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic power generation equipment is extremely refined, reliable, stable, long-lived, installation and maintenance Simple.

 

Definition of photovoltaic power generation

 

English name: Solar photovoltaics (PV)

 

Solar power generation is divided into thermal power generation and photovoltaic power generation. Regardless of production and sales, development speed and development prospects, CSP cannot keep up with photovoltaic power generation. It may be that photovoltaic power generation is widely used and there is less exposure to solar thermal power generation. Generally speaking, solar power generation often refers to solar photovoltaic power generation, referred to as photovoltaic power generation.

 

Photovoltaic power generation theory

 

Photoelectric conversion of solar energy refers to the process in which photons of the sun's radiant energy are converted into electrical energy through semiconductor materials, usually called the "photovoltaic effect", and solar cells are made using this effect. When sunlight hits a semiconductor, part of it is reflected off the surface, and the rest is absorbed or transmitted by the semiconductor. Of course, some of the absorbed light turns into heat, and other photons collide with the valence electrons of the atoms that make up the semiconductor, thus generating electron-hole pairs. In this way, light energy is converted into electrical energy in the form of generating electron-hole pairs. The battery elements formed in this way can be connected in series and parallel to generate a certain voltage and current, and output power.
