Solar street lamps design case

First, assume the bright city of intelligent street lamp light up 11 hours a day, six hours and the whole load, 5 hours male child. The daily power consumption of lamps and lanterns is: 24 wx ( 6 + 2. 5) =204W。 Close to shenzhen and guangzhou, we choose the data of guangzhou, to simulate the shenzhen daily peak power generation 3.

in the first place, assuming that the city of light intelligent street lamp light up 11 hours a day, 6 hours of full load, 5 hours male child. The daily power consumption of lamps and lanterns is: 24 wx ( 6 + 2. 5) =204W。

close to shenzhen and guangzhou, we choose the data of guangzhou, to simulate the shenzhen daily peak power generation 3. 52 hours, therefore the theoretical power of solar panels: 204/3. 52 = 58 wh, LED street light, assume that each will meet 2 days rainy day, 7 days, 7 days to 9 days with enough, so power is: ( 58X9) /7=75W。 Counting component loss and efficiency of the solar panels, power is: ( 75W/0. 9) / 08 = 105 w, the power for 24 v, should choose 34 v solar panels, will be same proportion choice, namely 150 wh. Battery is simpler, nine days of electricity, 24 w / 24 vx8. 5 x9/08 = 96啊。
