Solar street light configuration

Such as: a: solar energy solar street light configuration to calculate the current 12 v battery system; 2 only 30 w lamp, a total of 60 watts. Present current = 60 w 12 v = 5 A 2: capacity calculation such as street lamp lighting time every night. 5 hours, the actual lighting for 7 hours (full load h) ; Example 1:1 road solar led solar street light ( If at 7:30 in the evening to open 100% power, the night 11 to 50% power, 100% power again after 4:00 in the morning, at 5:00 am close) Example 2:2 way the leds ( Low voltage sodium lamp, energy-saving lamps, energy-saving lamps, etc. ) ( As two road opened at 7:30 in the evening, night 11 close road 1, at 4 in the morning to open 2 road, 5:00 in the morning off) Need to meet the lighting needs of continuous rainy day 5 days. ( Plus 5 days before the rainy night lighting, 6 days) Battery = 5 a * (7 h 5 + 1) Days = 5 a * 42 h = 210 AH in addition to prevent the battery charge and discharge, battery charge in general to around 90%; Discharge remaining 5% - 20%. So 210 ah is real standard in the application of 70% - 85%. Also, depending on the load, measure the actual loss, the actual working current affected by the constant current source, ballast, line loss, etc, may be on the basis of 5 a increased 15% About 25%. Three: peak solar street lamp lighting of accumulative total of every night time need for 7 hours ( h) ; Panels accept effective illumination time is 4 a day on average. 5 hours ( h) ; * less ease demand for panels reserve amount of 20%. WP÷17. 4 v = ( 5A × 7h × 120%) ÷ 4. 5 hwp÷17。 4 v = 9。 33 wp = 162 ( W) 4. 5 h a day light coefficient of rizhao region near the time for the middle and lower reaches of the Yangtze river. In the components of solar street lamps, line loss, the wastage of the controller, and power consumption of the ballast or constant current source is different, may be 15% in actual application About 25%. So is the theoretical value of 162 w, according to the actual situation to increase. Dear customer: hello!
