The solar photovoltaic street lamps are powered by crystalline silicon solar cells
The solar photovoltaic street lamp is powered by crystalline silicon solar cell, and the maintenance free valve controlled sealed battery (gel cell) is used to store the electric energy. LED lamps are used as the light source and controlled by the intelligent charge and discharge controller, which are used to replace the traditional public electric lighting street lamps. Solar photovoltaic street lamp system can ensure normal operation in rainy weather for more than 15 days! Its system consists of LED light source (including driver), solar panel, battery (including battery insulation box), solar street lamp controller, street lamp pole (including foundation) and auxiliary material wire [1].
The solar cell module generally adopts monocrystalline silicon or polycrystalline silicon solar cell module; the LED lamp head generally adopts high-power LED light source; the controller is generally placed in the lamp pole, with light control, time control, overcharge and over discharge protection and reverse connection protection, and the better controller has the function of adjusting the lighting time, half power function, intelligent charging and discharging function in all seasons; the battery is generally placed Underground or there will be a special battery incubator, which can be valve regulated lead-acid battery, gel battery, aluminum iron battery or lithium battery. The solar lamp works automatically and does not need to dig a trench for wiring, but the lamp pole needs to be installed on the embedded parts (concrete base).
