How to calculate the configuration for solar street light
04.03.2018· Calculate Power of Solar Panel (Wp) Solar street light need work 7h each night, while it is about average 4.5h that solar panel can touch enough sunlight. The voltage of solar panel is 17.4V. It need configure more 20% for power of solar panel. Wp/17.4V= (5A*7h*120%)/4.5h, So, Wp=162W.
