Power consumption = LED solar street light power * full power working time the storage capacity of the battery = the daily power consumption * the number of support in rainy and cloudy days: and then divide by the voltage of the lithium battery to get the capacity, for example, we use 11.1V lithium battery, the capacity is 405AH/11.1V≈36AH Solar panel power=daily power consumption*2/(peak hours of sunshine at installation location*generation efficiency)
60w led solar street light, lighting time 12 hours per night Working mode,80% brightness 3 hours,50% brightness 4 hours,30% brightness 5 hours. 3*0.7+4*0.5+5*0.3=5.6 hours Lithium battery/LiFePo4 battery 12.8V Charging time,day time sunshine 5 hours Solar panel efficiency 80%
How to do LED street lamp waterproof? LED street lamp maintenance: take solar panels as an example, usually maintenance to check the azimuth of solar panels, whether there are branches, leaves or other foreign direct occlusion. Whether in the shadow area of other objects, whether the surface has...

How many watts of solar panel to charge full the batteries? The LED 30W lamp(loads),the battery, the controller,the solar panel. 30W lamp working for 12 hours( 3hours 80% brightness,4hours 70% brightness,5hours 50% brightness) Power consumption=30W*(3*80%+4*50%+5*30%)=177WH If the lamp come on 3 rainy days and the battery is 12V, it should be 177WH*3days/12V=44.25AH The solar panel should bear tonight and tomorrow night consumption,the consuption is 177WH*2=354WH. Solar panel power=354WH/(4*solar panel efficiency0.75)=118W
