Solar lights use about 10-14 hours a day price, and 10-15 days of continuous rain. Among the more common solar cells and more practical monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cell manufacturing, three solar lights, plenty of sunshine in good sunlight eastern and western regions of solar lights and equipment, use of polysilicon solar cells as well, because of polycrystalline silicon solar cell production process is relatively simple, the price is lower than the single crystal. Intelligent control system: charging and discharging, lamps work and shut down time and brightness settings, overcharge, over discharge, temperature control.
