system composition

The solar street light system can ensure normal operation in cloudy and rainy weather for more than 15 days! Its system consists of several parts, including a bracket, LED lamp holder, solar lamp controller, battery (including battery insulation box), and lamp pole.

Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp holders generally use high-power LED light sources; The controller is generally placed inside the lamp pole and has functions such as light control, time control, overcharging and discharging protection, and reverse connection protection. More advanced controllers have functions such as adjusting the lighting time throughout the year, half power function, and intelligent charging and discharging function; Batteries are generally placed underground or equipped with specialized battery insulation boxes, which can be valve regulated lead-acid batteries, colloidal batteries, iron aluminum batteries, or lithium batteries. The solar lighting fixtures are fully automatic and do not require trenching and wiring, but the lamp poles need to be installed on embedded parts (concrete bases).

operational principle

Explanation of the working principle of solar street lights: During the day, under the control of an intelligent controller, solar street lights are illuminated by sunlight, absorbed by solar panels, and converted into electrical energy. During the day, solar cell components charge the battery pack, and at night, the battery pack provides power to the LED light source, achieving lighting functions. The DC controller can ensure that the battery pack is not damaged due to overcharging or discharging, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
