When the 670w solar panel receives light irradiation, the silicon material absorbs a part of the photons, and the silicon atoms receive the energy of the photons, which in turn causes the electrons to migrate, forming free electrons that gather on both sides of the P-N junction to cause a potential difference, and the circuit is connected externally At this time, through the action of the voltage, the current flows 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. Generally speaking, the battery sheet, tempered glass, EVA, TPT and other materials determine the service life of the 670w solar panel. The service life of better solar panels used in materials can reach about 25 years. It should be noted that the 670w solar panel is affected by environmental factors and will age over time.
