Briefly describe the configuration matching problem of the complete solar street light system

　　 A complete set of solar street light system includes: light source, controller, battery, solar cell components and lamp body. Among them, LED light source, controller, battery and other components are the key to determining the performance of the entire system, and the design must be optimized and configured reasonably during the design process. The problem of matching degree of solar street light components. Now many solar street light manufacturers often pursue styling design too much, and ignore the most important system matching design requirements. Without in-depth consideration, only simple calculations are carried out, which finally leads to There are a lot of problems with lamps, and some manufacturers do not hesitate to sacrifice the stability of solar street lamps in order to create a price advantage for their products. These practices are not advisable. The matching design of various components of solar street lights is an important factor related to the reliability and stability of the whole set of solar street lights, so each manufacturer should pay attention to it. Here is a brief introduction to several aspects that should be considered: 　　1, the power generation of solar panels The ratio of power consumption to the load should be reasonable; 　　2, the ratio of power consumption and battery capacity should meet the requirements of the number of continuous rainy days, and the depth of discharge should be reasonable; 　　3, the ratio of solar panel charging current and battery capacity is reasonable; 　　4, load The ratio of discharge current to battery capacity is reasonable. In addition, because the power generation of solar cell modules varies with weather conditions and sunshine time, it is very unstable. Therefore, the charge and discharge control of the battery in the solar street lamp is more complicated than the charge and discharge control of the battery in ordinary applications. At this time, whether the controller design matches or not directly determines whether the entire solar street light system can run smoothly.
