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 light radiation ability of the sun into electrical energy, send it to the battery for storage, or push the load to work. The quality and cost of solar panels 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 for one day, and at the same time, it can also protect the battery from overcharge and overdischarge. In places where the temperature difference is large, the general controller will still have the function of temperature compensation. Other additional functions such as light-controlled switches and time-controlled switches should be optional on the controller.

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 electrical energy generated by the solar panel in the battery when there is sunlight, and release it when needed at night.

Inverter: In many occasions, it is necessary to provide 220VAC, 110VAC AC power. Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC electrical appliances, its function is to convert all the DC power generated by the solar power generation system into AC power, so the inverter is needed.
