How do solar street lights generate electricity and work?


With the continuous development of photovoltaic technology, solar street lights are becoming more and more common in our lives. We all know that after solar energy passes through the sun during the day, the light energy is converted into electrical energy, and then stored by the battery, and the battery is stored at night. The light source provides electric energy to achieve the lighting effect.

1, solar street light battery panel

The solar panel is the core part of the solar power system, and it is also 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 role of the solar controller is to control the working status of the entire system, and to protect the battery from overcharge and overdischarge. 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;

3, battery

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 generated by the solar 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.
