Overview of solar energy and the working principle of solar cells

Overview of solar energy Solar energy generally refers to the radiant energy of sunlight, which mainly comes from the nuclear fusion reaction inside the sun. These energies travel in all directions through space in the form of electromagnetic waves. The energy received by the earth’s atmosphere accounts for only 2.2 billion parts of the total solar […]

Discontinuous transmission and continuous transmission system

The discontinuous variable speed power generation system is also called a two-speed asynchronous power generation system. Its wind wheel does not change continuously with the change of wind speed, but when the change of wind speed reaches a certain value, the speed changes. It can be realized by using two generators with different speeds or […]
