The photovoltaic system is composed of a solar cell array, a battery pack, a charge and discharge controller, an inverter, an AC power distribution cabinet, an automatic solar tracking system, and an automatic solar component dust removal system. The role of each part of the equipment is:
Solar cell array
In the case of illumination (either sunlight or illumination from other illuminants), the battery absorbs light energy, and the accumulation of a different charge at both ends of the battery produces a "photogenerated voltage", which is the "photovoltaic effect". Under the effect of the photovoltaic effect, the two ends of the solar cell generate an electromotive force, which converts light energy into electrical energy, which is a device for energy conversion. Solar cells are generally silicon cells, which are classified into single crystal silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells.
