Since solar street lamps are powered by the sun, how do we get to calculate the solar street lamp configuration? Because Solar street Lights is generated by the sun, so we need to know what to calculate, I first from the Solar street L AMP per night with how much electricity to start, only know the electricity per night, the corresponding can calculate how Much electricity to send each day. Case:in the middle and lower reaches of the Yangtze River (peak Sunshine 4H) Beautiful countryside construction process, Installed 30W LED light source, every night Lights 7 hours, to ensure the 3-4 rainy days under normal Lights; We calculate the power consumption of this configuration first:30w LED light source, solar street lamp, normal to make 12 V system, It can be concluded the current size of 30W, 30w/12v=2.5a current, power consumption is 2.5a*7h=17.5ah per

Night, if there is no Sun guarantee 3 to 4 rainy days normal lights, the size of the battery is 17.5ah*4=70ah But because the solar street lamp battery have overshoot and over-discharge protection, the normal solar street lamp batter Y charging Depth is 90%, the discharge depth are 70%, that's to say 70AH configuration was accounted for the total Configur ation of 70%, the real capacity of the battery =70ah/0.7=100ah; Battery board in order to meet the daily power consumption, the Battery board must generate more than equal to power consu Mption, we assume that the battery Panwa number of x,x/17.5v (17.5V represents the 12V battery board operating voltage) = Operating Current, x/17.5v*4h (effective illumination time) =17.5ah, Thus we can infer the size of the required solar pane L X=76.56W, but because the solar street lamp system in the presence of line loss, controller loss, and so on, the normal Loss of 5%-25%, that's, in the configuration of the battery board process, normal according to loss 20% calculation, you Can calculate the battery board x true Size x =76.56w* (1+0.2) =92w, Solar Controller configuration, 30W led discharge cur Rent of 2.5A, charging current of 92w/17.5v=5.2a, so in the selection of the controller can choose 10A, the New century Li Ghting Group 3 A controller Generation 5 A, charging current is 10A + in line with, if you configure 10A control Ler, the actual need not so large, the controller of the current as long as more than the power generation and charging CA n Be, the and the process of configuring the controller is not the bigger the better. Know how to calculate, I first from the solar street lamp every night with how much electricity to start, only know the power consumption per night, the corresponding only

Can calculate the amount of electricity to be sent per day. Case: In the middle and lower reaches of the Yangtze River (peak Sunshine 4H) Beautiful countryside construction process, installed 30W LED light source, every night Lights 7 hours, to ensure that 3-4 rainy days under normal lights; we calculate the power consumption of this configuration first: 30W LED light source, solar street lamp, normal to make 12V system, It can be concluded that the current size of 30W, 30w/12v=2.5a current, power consumption is 2.5a*7h=17.5ah per night, if there is no Sun guarantee 3 to 4 rainy days normal lights, the size of the battery is 17.5ah*4=70ah

But because the solar street lamp battery has overshoot and over-discharge protection, the normal solar street lamp battery Charging depth is 90%, the discharge depth is 70%, that is to say 70AH configuration is accounted for the total configuration of 70%, the real capacity of the battery =70ah/0.7=100ah; Battery board in order to meet the daily power consumption, the battery board must generate more than equal to power consumption, we assume that the battery Panwa number of x,x/17.5v (17.5V represents the 12V battery board operating voltage) = operating Current, x/17.5v*4h (effective illumination time) =17.5ah, Thus we can infer the size of the required solar panel x=76.56w, but because the solar street lamp system in the presence of line loss, controller loss, and so on, the normal loss of 5%-25%, that is, in the configuration of the battery board process, normal according to loss 20% calculation, you can calculate the battery board x true Size X =76.56w* (1+0.2) =92w, Solar Controller configuration, 30W led discharge current of 2.5A, charging current of 92w/17.5v=5.2a, so in the selection of the controller can choose 10A, the New century lighting group 3A controller Generation current 5 A, Charging current is 10A more in line with, if you configure 10A controller, the actual need not so large, the controller of the current as long as more than the power generation and charging can be, so in the process of configuring the controller is not the bigger the better.
