Third, photovoltaic energy storage system principle
Photovoltaic energy storage system mainly includes photovoltaic power generation and energy storage two processes.
Photovoltaic power generation: The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. Photovoltaic panels (composed of multiple photodiodes) first receive sunlight and convert the energy of sunlight into electricity. The photovoltaic power station is separated into different areas by the positive and negative carriers generated by the photoelectric effect, and then forms a current, which can conduct electricity through an external circuit. The inverter converts direct current into alternating current and outputs it to the user or feeds it back to the grid.
Photovoltaic energy storage: During the charging process, the sun shines on the photovoltaic panel, stimulates the electrons in the photovoltaic cell, generates direct current energy, which is converted into alternating current through the inverter and transmitted to the energy storage equipment, such as the battery pack. The battery pack stores the power for later use.
Discharge process: When the energy demand is higher than the energy currently generated by the photovoltaic power generation system, the energy storage system will be activated to provide power supply.
