How to judge the capacity of solar street light battery

Solar street light battery is the application of solar street light. The function of solar street light battery is to store the electrical energy generated by solar cell components. When the light is insufficient or illuminated at night, it is another new energy street light. The currently used solar energy The most commonly used batteries for solar street light are: sealed lead-acid batteries, gel batteries, the voltage is generally 12V or 24V, which is widely used because of their maintenance-free and high environmental protection. The solar street light battery configuration calculation method is as follows: 1. Calculate the current first: For example: 12V battery system; 1 30W LED lamp head, currentu003d30W÷12Vu003d2.5A 2: Calculate the battery capacity requirement: For example: each street light The cumulative lighting time at night needs to be 6 hours (h) at full load; it needs to meet the lighting requirements for 3 consecutive days of rainy days. (3 days plus the lighting the night before the rainy day, 4 days in total) Batteryu003d2.5A×6h×(3+1)daysu003d2.5A×24hu003d60AH About 90%; discharge remaining about 30%. So 60AH is only about 60% of the real standard in the application. At this time, the size of the solar street light battery should be 60AH÷60%u003d100AH.
