Solar panel introduction

Solar panel , also known as solar cell module, is a photoelectric semiconductor sheet that uses sunlight to generate electricity directly, and is an assembly of several solar cells assembled on a board in a certain way, which is the core part of the solar power generation system.

Solar power generation There are two ways of solar power generation, one is the light-heat-electricity conversion mode, the other is the light-electricity direct conversion mode.

(1) Light-heat-electricity conversion method through the use of solar radiation generated heat energy generation, generally by the solar collector will be absorbed by the heat into the steam of the working medium, and then drive the turbine power generation. The former process is the light-heat conversion process; The latter process is the heat-electricity conversion process.

(2) The light-electric direct conversion method is to use the photoelectric effect to directly convert solar radiation into electrical energy, and the basic device for light-electric conversion is a solar cell. A solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect, and is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will turn the sun's light energy into electrical energy and generate current. When many cells are connected in series or in parallel, they can become a solar cell array with relatively large output power.
