Solar street lamps use solar energy as power to save electricity costs in the later stage, which is becoming more and more popular in the market. However, in addition to paying attention to its photoelectric conversion rate, battery capacity and other parameters, what should we pay attention to? Let Xiaobian take you to have a look~
1、 Pole height selection
When purchasing solar street lamps in Minggui, you can generally choose the type directly installed on the wall or column, but when it comes to the most practical, it is still necessary to equip with lamp poles, and the height of lamp poles is generally selected according to the road width. The height of lamp poles with the same or slightly greater than the road width is the best.
1. 3-4m light poles are selected for general single lane rural roads;
2. 5-7m light poles shall be selected for two lane rural roads;
3. 8-12m light pole shall be selected for four lane or main traffic road;
4. Courtyard or other scene lighting is selected according to the lighting range.
2、 Wattage selection of LED lamp cap
The wattage of street lamp shall be determined according to the purpose of street lamp, lamp pole height and LED street lamp lumen value. Generally, LED lamp caps with slightly lower wattage can be selected for roads and scenes with less pedestrian traffic, and LED lamp caps with slightly higher wattage can be selected for roads and scenes with more pedestrian traffic. The higher the pole, the higher the wattage of the LED lamp cap. For example, 15-20 watts are recommended for 3-4m poles and 50-100 watts are recommended for 8-12m poles.
In addition to the purchase and installation of solar street lamps, the name of Xiaobian also brings some little knowledge about installation. What are there?
1、 Installation spacing and position of solar street lamps:
According to the construction drawings and the geological conditions of the survey site, where there is no sunshade at the top of the street lamp, the installation position of the street lamp shall be determined based on the distance between the street lamps of 20-50m, otherwise the installation position of the street lamp shall be adjusted appropriately.
1. The road width is about 3-4m, the lamp pole is 3-4m, the LED lamp cap is 15-20w, and the installation distance should be 20-25m;
2. The road width is about 5-7m, the lamp pole is 5-7m, the LED lamp cap is 30-50w, and the installation distance should be 30-40m;
3. The road is about 8-12m wide, 8-12m light pole, 50-120w LED lamp cap, and the installation distance should be 30-50m.
2、 Orientation of solar panel
The solar panel should face the sun and the direction with the most sufficient sunshine time. Generally, in central and South China, the solar panel faces due south. In West and North China, the solar panel faces due south by west 5 degrees. It should be noted that the direction of the solar panel can be adjusted appropriately according to the shelter of buildings or trees, generally within 20 degrees to the West or East (the west effect is better than the East). If you think this is not intuitive enough, you can take a look at the video installation tutorial named solar street lamp.
Of course, if the construction of large-scale installation projects is still very difficult, Minggui can also undertake construction projects, so that you have no worries about installation!
If you want to know more about solar street lamps, you can pay attention to the name of Xiaobian and don't get lost~
