3000 watt solar generator china is a device that responds to light and converts light energy into electricity. There are many kinds of materials that can produce photovoltaic effect, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, indium selenium copper and so on. Their power generation principles are basically the same, and the crystal is taken as an example to describe the photovoltaic power generation process.

P-type crystalline silicon can be obtained by doping phosphorus to form N-type silicon, forming a PN junction. When the light irradiates the surface of the solar cell, some photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to migrate and become free electrons to gather on both sides of the PN junction to form a potential difference. When the circuit is turned on, under the action of this voltage, a current will flow through the external circuit to generate a certain output power. The essence of this process is: the process of converting photon energy into electrical energy.
3000 watt solar generator china consists of the following three parts: solar battery components; charge and discharge controllers, inverters, test instruments and computer monitoring and other power electronic equipment and batteries or other energy storage and auxiliary power generation equipment. As a key component, solar cells have a long service life, and the life of crystalline silicon solar cells can reach more than 25 years.
