How much solar panels do you need to make a 15W LED solar street lamp?
Here we give our solar power street lights (or systems) calculation method, I hope useful to you. 1. solar panels power (electric power = W) * every time the lights (H), average sunshine time * peak loss coefficient (2) = 2. of battery capacity with electrical power (W) every time the lights * H / {system voltage (12V or 24V)} * (rainy days +1) * loss coefficient (1.75)
According to your work time and the continuous rainy days, and then calculate the power: LED * * working time of continuous rainy days = depth of discharge battery (AH) battery discharge depth / sunshine time / silicon solar panel power = charging efficiency
This is based on the daily light hours, as well as the average sunshine hours in the region, the number of days required to calculate the rainy days.
