What is the working principle of solar lights?
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 role of each part is:
Solar panels are the core part of solar power generation systems. It is also the most valuable part of the solar power system. Its role is to convert the sun’s radiant power into electrical energy. Or send it to the storage 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.
The role of the solar controller is to control the working status of the entire system. And play the role of overcharge protection and overdischarge protection for the battery. 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 time control switch should be optional options of the controller.
The battery is generally a lead-acid battery. 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. Release it when needed.
In many occasions, inverters need to provide 220VAC, 110VAC AC power. Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. 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.
