Solar photovoltaic street lights are powered by crystalline silicon solar cells, with maintenance free valve controlled sealed batteries (colloidal cells) storing electrical energy. LED lamps serve as light sources and are controlled by intelligent charging and discharging controllers, replacing traditional public power lighting street lights. The solar photovoltaic street light system can ensure normal operation for more than 15 days in rainy weather! Its system consists of several parts, including LED light source (including driver), solar panel, battery (including battery insulation box), solar street lamp controller, street lamp pole (including foundation), and auxiliary materials and wires.
Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp heads generally use high-power LED light sources; The controller is usually placed inside the lamp post and has functions such as light control, time control, overcharge and over discharge protection, and reverse connection protection. Better controllers have the ability to adjust the lighting time in all seasons, half power function, intelligent charging and discharging function, etc; Batteries are generally placed underground or have specialized battery insulation boxes, which can be valve regulated lead-acid batteries, gel batteries, iron aluminum batteries, or lithium batteries. Solar powered lighting fixtures work fully automatically without the need for trench digging or wiring, but the lamp post needs to be installed on a pre embedded part (concrete base).
