Working principle of the system is simple, the use of light born v effect principle of solar cells, solar panels during the day to receive solar radiation and translated into electricity output, after stored in the storage battery charging and discharging controller, the night when the illumination was gradually reduced to about 10 lux
working principle of the system is simple, the use of light born v effect principle of solar cells, solar panels during the day to receive solar radiation and translated into electricity output, after stored in the storage battery charging and discharging controller, the night when the intensity of illumination is gradually reduced to about 10 lux, solar panels open circuit voltage is 4. Around 5 v, charge and discharge controller to detect the voltage value of the action, the battery to discharge lamp holder. Battery discharge 8. Five hours later, LED street lamp, charging and discharging controller action, battery discharge end.
