The solar power generation system consists of solar panels, solar controllers, and batteries. If the output power is AC 220V or 110V, an inverter is also required. The functions of each part are:


solar panel


The solar panel is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Its function is to convert the radiant energy of the sun into electrical energy, or send it to the battery for storage, or drive the load to work. The quality and cost of the solar panel will directly determine the quality and cost of the entire system.


Solar Controller


The function of the solar controller is to control the working state of the entire system, and to protect the battery from overcharge and overdischarge. In places with large temperature difference, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be the functions that the controller should have.


battery


Usually lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries can also be used in small systems. Since the input energy of the solar photovoltaic power generation system is extremely unstable, it is generally necessary to configure the battery system to work. Its function is to store the electrical energy emitted by the solar panel when there is light, and release it when needed.


Inverter


In many occasions, it is necessary to provide 220VAC, 110VAC AC power. Since the direct output of solar energy is generally 12VDC, 24VDC, 48VDC, in order to provide power to 220VAC electrical appliances, it is necessary to convert the DC power generated by the solar power system into AC. power, so a DC-AC inverter is required. In some occasions, DC-DC inverters are also used when loads with multiple voltages are required, such as converting 24VDC power into 5VDC power.
