Solar Eco-friendly Photovoltaic Fan

Working Principle1. Conversion of solar energy into electrical energy The top of the photovoltaic solar fan is equipped with a high-efficiency photovoltaic panel, which uses advanced monocrystalline silicon technology. When sunlight shines on the photovoltaic panel, photons interact with the semiconductor material in the photovoltaic panel. The energy of the photons prompts the electrons in the semiconductor to obtain enough energy to break free from the atomic bondage and generate electron-hole pairs. Under the action of the electric field inside the photovoltaic panel, the electrons and holes move in opposite directions respectively, forming a current, realizing the conversion of solar energy into electrical energy.2. Distribution and use of electrical energy The converted electrical energy has two main destinations. A part of it is directly supplied to the DC brushless motor of the fan. The motor uses electrical energy to generate a magnetic field, drives the rotor of the motor to…
