The configuration of solar street lamps is to determine the power of the light source used according to the height and spacing of the lamp poles and the road level. The actual lighting effect is excellent and can match the road level. If you want to match the standard of urban road lighting, the power cannot exceed the customer's budget. The power size directly affects the power setting of photovoltaic modules and the size setting of batteries in the next step, and these two items account for nearly 60% of the project investment proportion. There are many factors that affect the determination of the power of PV modules, among which the annual average sunshine hours of the project location are difficult to determine. Even the locations at the same latitude may have different annual average sunshine hours due to different terrain. The actual power consumption of light sources and the daily working status can accurately calculate the daily power consumption ampere hours, The power of PV modules can be determined by combining the annual average sunshine and the annual minimum sunshine. The configuration of solar street lamps should first determine the lamp power. Generally, 30-60 watts are used for rural road lighting, and more than 60 watts are needed for urban roads. It is not recommended to use solar power for LED lamps with more than 120 watts. The configuration is too high, the cost is high, and many problems will occur later.
