Solar energy is a green and pure energy, and the development of solar energy is the goal of the energy industry for a long time in the future. At present, our use of solar energy is mainly solar heating and solar power generation, and after years of development, solar power generation has become a relatively mature system. Although solar power has not yet become the main energy source, it can already share part of the power pressure. The following small series will introduce the various components of the solar power generation system and their functions.

The solar power generation system consists of a solar cell group, a solar controller, and a battery (group). 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 generation system and the most valuable part of the solar power generation system. Its function is to convert the radiation capacity of the sun into electrical energy, or 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.

(2) 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-controlled switches and time-controlled switches should be optional on the controller.

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

(4) 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, it is necessary to convert the DC power generated by the solar power generation system into AC power, so a DC-AC inverter is required. In some occasions, when multiple voltage loads are required, a DC-DC inverter is also used, such as converting 24VDC power into 5VDC power (note that it is not a simple step-down).

The above is a detailed introduction of the solar power generation system. I hope it can help you have a more comprehensive understanding of solar power generation.
