The solar street light works by using solar power generation, battery storage, and the controller to control the charging and discharging of the battery. The controller is divided into two types: light control and time control. During the day, when the sun shines on the surface of the solar cell, the electric energy generated by the solar cell charges the battery through the controller; at night, the light gradually weakens, and the working voltage and working current of the solar cell continue to decrease. When the working voltage is lower than the controller setting When the voltage is high, the controller starts to start the load, and the solar street light lights up at this time; when the set time is reached or the ambient light is too strong, the controller automatically turns off the load and the solar battery starts to charge. This cycle continues.

The solar street light is powered by high-efficiency monocrystalline (polycrystalline) silicon solar cells, uses VRLA batteries to store electrical energy, uses high-efficiency energy-saving lighting, and adopts advanced charging and discharging and lighting control circuits, with reliable performance, high luminous efficiency, high brightness, and easy installation. , No need to lay cables and wires, no AC power and electricity charges, DC power supply, photosensitive control, safe and reliable, energy saving, economical, environmentally friendly, practical (depending on the configuration and model, charging can be used for 3~7 days a day), long life ( Solar cells can be used for 15 to 20 years, and batteries can be used for 5 to 7 years), which is the development direction of outdoor solar street lighting manufacturers in the future.
