Solar street lights have different specifications for different regions-solar street light manufacturers

The actual effective sunshine time and light intensity in different regions are often different, so solar street lamp manufacturers will also customize and produce street lamps with different performance specifications according to the actual situation in different regions. Therefore, when installing or transforming solar street lights in different regions, you must pay special attention to choosing the most suitable street lights based on the actual situation in your area, and strive to not waste resources and meet daily use.

First of all, we need to understand the working principle of solar street lights. It uses the photovoltaic effect principle of solar cells. During the day, solar cells absorb solar photon energy to generate electricity, which is stored in the battery through the controller. When night falls or the brightness of the lights around the lamp When the value is lower than a certain value, the controller will automatically discharge operation to turn on the street light and start lighting.

Data required for the design of solar street lights-find the longitude and latitude of the place of use by knowing where the solar street lights are used. Determine the inclination angle and azimuth angle of solar cell modules and calculate the solar standard peak sunshine time in the area through (China Solar Radiation Database on Different Inclined Surfaces). The power (W) of the light source selected for the street lamp. The power of the light source directly affects the parameter stability of the entire system. The working hours of solar street lights every night (H). This is the core parameter that determines the size of the components in the solar street light system. By determining the working time, the daily power consumption of the load and the corresponding charging current of the solar cell components can be calculated preliminarily. The number of consecutive cloudy and rainy days that solar street lights need to maintain (d). This parameter determines the size of the battery capacity and the solar cell module power required to restore the battery capacity after rainy days. Determine the number of days D between two consecutive cloudy and rainy days. This is to determine the battery pack power required for the system to fully charge the battery after a continuous rainy day.

So when purchasing solar street lights in different regions, you must pay special attention to whether the design ideas and key points of the system are in line with the actual local conditions. Don't just pursue low prices for the sake of saving investment, and you can't blindly pursue high performance and cause resources. Waste.
