Solar street lights are powered by crystalline silicon solar cells, with maintenance free valve controlled sealed batteries (colloidal batteries) storing electrical energy. Ultra high brightness LED lamps serve as light sources and are controlled by intelligent charging and discharging controllers to replace traditional public power lighting street lights. Solar street lamps are composed of LED light sources, solar panels, batteries, battery insulation boxes, solar street lamp controllers, street lamp poles, and auxiliary materials and wires, and are powered by clean energy solar energy.

The working principle of solar street lights is: under the control of an intelligent controller, the solar panel absorbs solar energy during the day and converts it into electrical energy, charging the battery pack. At night, the battery pack provides power to the LED light source, achieving lighting functions. The excess electricity can be stored to ensure normal operation in rainy and cloudy weather.

The price of solar streetlights is influenced by factors such as pole height, lamp head brightness, power, and lighting time. The price of a complete set of solar streetlights includes solar streetlight controllers, battery panels, batteries, battery boxes, streetlight poles, streetlight fixtures and light sources, lamp pole flange sleeves, basic embedded parts, and built-in wires. The approximate price varies from 2500 to 10000 yuan depending on the configuration. For example, a solar street lamp with a height of 6 meters, a lamp holder of 30 watts, and 6 hours of light per day would cost around 2400 yuan
