•For example: ESL-16
solar panel: 14.5W, Li-ion battery: 97.68WH, LED: 1200lm, lighting mode: 5Hrs smart lighting + 7Hrs 25% lighting
Below is the formula for reference:
•LED lighting time:
T(time)=battery power/(LED power*energy saving )coefficient=15.35Hrs
Lighting time per day：4.75Hrs
Lighting days=15.35/4.75=3.2days
It means the lighting will work for 3 raining day after battery full charged.
•Solar charging time:
T(time)=battery capacity/solar charging current=(97.68/3.7)/ (14.5/5.5)=10Hrs, which means it need 2 sunny day for full charing the battery.
•Left power after daily solar charging & using:
Left power=(daily solar charging-daily using)/daily using=61.6%
It means solar charge one day, the lighting will work 1.6days.
