Formula of Solar System Configu1 Firstly calculate the current:1, Firstly calculate the current:
For example: 12V battery system; 2pcs 30W lamps, a total of 60 wThe current I = 60W ÷ 12V = 5A
2, Calculate the battery capacity requirements:, y p y q
For example: street light working time is 7 hrs per day, need to meet wornight before the night of lighting, total 6 days)
Battery capacity = 5A × 7h × (5 + 1) daysBattery capacity = 5A × 7h × (5 + 1) days= 5A × 42h= 210AH
Besides, in order to prevent the battery overcharge and over discharge, capacity. So 210AH is only about 75% of the in the application standard.
3, Calculate the peak power(WP)Given the total working time is 7 hours(h) per days. For example: the effThe reserved capacity is 20% at least of the battery. here it is,
WP ÷ 17 4V = (5A × 7h × 120%) ÷ 4 5hWP ÷ 17.4V (5A × 7h × 120%) ÷ 4.5hWP ÷ 17.4V = 9.33AWP = 162 (W)
So the choice of two peak power of 80 ~ 85Wp solar modules is better.Also in the PV module of a streetlight, the loss of wire, controller and balactual power may be 5% 25% higher So 162W is only the theoretical vaactual power may be 5% -25% higher. So 162W is only the theoretical va
