The first step in designing a solar street light system is to find out the wattage and energy consumption of the LED street lights, as well as the energy consumption of other parts that require solar power, such as WiFi, cameras, etc. How to calculate the total energy consumption of your solar system?
Calculation of battery configuration of the solar street lamp 1： First, calculate the current: For example 12V battery system; two 30W lamps, 60 watts in total. Current = 60W ÷ 12V = 5 A 2： Calculate the battery capacity demand: For example the cumulative lighting time of street lamp every night needs to be 7 hours (H) with full load;

To calculate the daily energy consumption (total watt-hours) of a street light, you need to know two main factors: the wattage of the fixture during different time periods and the number of operating hours during each time period.
The total watt-hours is the electrical energy consumed by solar street lighting system every day, which directly affects the capacity of the battery and the power selection of the solar panel.
Based on the project conditions, we calculated the actual power consumption as follows: Total street light use = (60W x 4 hours) + (18 W x 6 hours) + (36 W x 2 hours) = 420 Wh/day, while based on customer’s requirement on wattage, the street light use= (80W x 4 hours) + (24 W x 6 hours) + (48 W x 2 hours) = 560 Wh/day.
