Solar road shenyang street lamps shall be provided with simple calculation method

One, the current accounting such as 12 v battery system, 2 lamps and lanterns of 30 w, a total of 60 w current: 60 divide; 12 v = 5 a second, the calculation of battery such as street lamps work 6 hours a day, four consecutive rainy day battery: 5 atimes; 6倍; 4 = 120 ah put in order to avoid a battery charge, charge to

a, currently accounting for example, the 12 v battery system, two 30 w lamp, a total of 60 w current: 60 points. 12 v = 5 a second, accounting batteries, for example, four consecutive rainy days, street lamp work 6 hours a day. Battery: 5 section; Six times; 4 = 120 ah in order to avoid the battery charge and discharge, the battery usually charge to 90%, the residual discharge is about 20%, so the actual capacity of battery is 120 points; 0. 7 = 170 ah. Solar panels are accounting, on average, solar panels to accept 4 every day. 5 hours of efficient lighting and solar panels required reserve amount of at least 20% were relaxed. Traffic signal warning lights, solar panels, 5 section; Six times; 120% split; 4. 5 times; 17. 4 v ( Charging voltage) = 140 watts ( Actual use is 150 - 160 watts) The middle and lower reaches of the Yangtze river sunshine coefficient of 4. 5 hours, and the middle and lower reaches of the Yangtze river for 5 hours. In addition, the components of solar street lamps, the controller of the line loss and power consumption are different, in use is likely to be about 5% 25%. Therefore, the formula to calculate the general on the basis of the theoretical value, should be increased according to actual situation.
