Choose which parameters should be considered when street lamps factory in henan

Type of solar LED street lamp is not fixed, it has a solar panel battery controller, LED light source, auxiliary light pole and some parts of the size of the various parts of them by using area of rizhao and need lighting time and continuous cloudy days every day

solar LED street lamp model is not fixed. It consists of solar panels, controller, led light source, light pole, and of some accessories. The size of each parts is through the use of area of sunshine, a day the time needed for lighting as well as the number of continuous cloudy to scientific computing. For example, a simple design method is as follows: 1 single arm lamp design thinking thinking. The choice of the solar cell component design requirements: in the Beijing area, load the input voltage is 24 v, the power consumption is 34. 5 watts, daily working time is 8. 5 hours, guarantee for seven consecutive rainy days. 一个。 Beijing over the past 20 years to the average annual amount of 107. 7 kcal per square centimeter. After a simple calculation, Beijing peak sunshine time is about 3. 424 hours. B。 Load the daily power consumption = = 12. 2 ahc, solar energy battery components needed for the total charging current = 1. 5 times; 12. 2 times; Division; ( 3. 424 times; 0. 85). = 5. 9 a here, for two consecutive rainy days between design shortest day is 20 days, 1. 05 is a combination of solar energy battery components system loss coefficient, 0. 85 is the battery charging efficiency. D, the minimum total power = 17 solar module. 2 times; 5. 9 = 102 watts standard battery pack, peak output of 110 watts, should choose a single 55 watt, in most cases to ensure that the street lamp system normal operation within a year. We may have for solar led street lamp manufacturers data more convincing.
