　　Power generation principle: The solar power generation system consists of solar panels, solar controllers, and batteries (groups). If the output power supply 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 generation system and the most valuable part of the solar power generation system. Its function is to convert the sun's radiation ability into electrical energy, or the quality and cost of sending it to the battery panel will directly determine the quality and cost of the entire system;

　　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 overcharge and over-discharge. In places with large temperature differences, qualified controllers should also have temperature compensation functions. Other additional functions such as light control switch and time control switch should be optional for the controller;

　　3. Batteries: Generally lead-acid batteries. In small and micro systems, nickel metal hydride batteries, nickel cadmium batteries or lithium batteries can also be used. Its function is to store the electrical energy emitted by the solar panel when there is light, and then release it when needed;

　　4. Inverter: In many occasions, it is necessary to provide AC power supply of 220VAC and 110VAC. Because the direct output of solar energy is generally 12VDC, 24VDC, or 48VDC. In order to provide power to 220VAC electrical appliances, the DC power generated by the solar power system needs to be converted into AC power, so a DC-AC inverter is required. In some situations, when loads of multiple voltages need to be used, a DC-DC inverter is also used, such as converting 24VDC power into 5VDC power (note, this is not a simple step-down).
