The solar power generation system is composed of solar battery packs, solar controllers, and storage batteries (groups). If the output power is AC 220V or 110V, an inverter is also required. The functions of each part are:
(1) solar panels: solar panels are the core part of the solar power system and the most valuable part of the solar power system. Its function is to convert the sun's radiant power into electric energy, or send it to the storage battery for storage, or drive the load to work.
(2) Solar controller: The function of the solar controller is to control the working status of the entire system, and to protect the battery from overcharging and over-discharging. In places with large temperature differences, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and internal time control switch should be optional for the controller;
(3) Battery: generally lead-acid battery, in small and micro systems, nickel-hydrogen battery, nickel-cadmium battery or lithium battery can also be used. Its function is to store the electric energy generated by the solar cell panel when there is light, and then release it when needed.
(4) Inverter: The direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide electrical energy to 220VAC electrical appliances, the DC power generated by the solar power generation system needs to be converted into AC power, so a DC-AC inverter is required.
Solar panels (also called solar cell modules) are assembled by multiple solar cells, which are the core part of the solar power system and the most important part of the solar power system.
