How Many Meters of Solar Street Light Installation Spacing Should Be?
Nov 04, 2024
As people pursue sustainable development and the demand for energy conservation and emission reduction increases, the application of solar street lights has gradually increased. Whether on highways or country roads, we can see solar led street lights everywhere. When installing solar street lights, you must pay attention to a value, that is, the installation distance between every two solar street lights. The installation interval of solar street lights has an important impact on the lighting effect and lighting efficiency. So how far is the installation interval of solar street lights? What factors need to be considered to determine the installation interval?
1. Road width where solar street lights installed
The width of the road where solar powered LED street lights are installed is one of the important factors that determines the installation spacing of street lights. The wider the road is, the larger the area that needs to be covered by light, and the spacing of solar led street lights may be relatively larger. If a symmetrical or staggered arrangement is adopted, the lighting effect can be further optimized.
Generally speaking, when the road width does not exceed 10 meters, a single-side cross-lighting method can be adopted, and the installation interval can be appropriately reduced; if the road width exceeds 15 meters, it is recommended to adopt a symmetrical lighting method on both sides, and the installation interval needs to be appropriately increased. For example, for a 6-meter-wide road, we usually select 20W or 30W solar led street lights, and the installation interval is recommended to be set at 25~30 meters. For new rural construction roads with a width of about 7 meters, commercial solar powered street lights with a height of about 7 meters are a better choice, and the installation spacing can be about 20~25 meters.

2. Installation method of solar street lights
Different installation methods of solar powered outdoor street lights will affect the illumination coverage area, thus affecting the actual installation spacing. There are three common installation methods for solar street lights: single-sided arrangement, double-sided staggered arrangement, and symmetrical arrangement. Let's take a look at them one by one!
A single-sided arrangement means installing the commercial solar powered street lights on one side of the road, with the light shining toward the center of the road. This installation method is more suitable for narrower roads, such as community roads or sidewalks, and the spacing will be set closer, generally 15-25 meters, to ensure the lighting effect.
A single-sided arrangement means installing the commercial solar powered street lights on one side of the road, with the light shining toward the center of the road. This installation method is more suitable for narrower roads, such as community roads or sidewalks, and the spacing will be set closer, generally 15-25 meters, to ensure the lighting effect.
Double-sided staggered arrangement means that the solar powered outdoor street lights are staggered on both sides of the road to form a staggered arrangement. The staggered installation method is more suitable for secondary roads or wider roads. The general installation distance is 25-35 meters, which can expand the lighting range and reduce the installation density of solar street lights while maintaining good lighting effects.
Double-sided symmetrical arrangement means that the commercial solar powered street lights stand opposite each other on both sides of the road and are installed symmetrically. This installation method is suitable for urban main roads or two-way lanes. The installation distance of symmetrical arrangements is generally 20–30 meters, which can form uniform illumination and reduce dark areas. Therefore, the spacing is larger than that of a single-sided installation, which can reduce the number of installations and save costs.
3. Height of the solar powered LED street light pole
The height of the pole of a solar street light directly determines the lighting range and uniformity of the solar street light. Therefore, the installation spacing of solar powered outdoor street lights will be different for different pole heights. Too low a height may lead to blind spots, while too high a height will cause energy waste. Therefore, when choosing the spacing of solar street lights, the height of the street lights also needs to be considered.
6-meter light pole: The installation spacing is usually 15-20 meters. Solar street lights at this height are suitable for narrow roads such as community roads and sidewalks.
8-meter light pole: The installation spacing is 20-25 meters. 8-meter-high solar street lights are suitable for secondary roads or small urban roads.
10-meter light pole: The installation spacing is 25-30 meters. 10-meter-high solar street lights are suitable for urban main roads or two-way lanes.
12-meter and above light poles: The installation spacing can reach 30-35 meters. This higher solar street light is suitable for wider roads or highways.
6-meter light pole: The installation spacing is usually 15-20 meters. Solar street lights at this height are suitable for narrow roads such as community roads and sidewalks.
8-meter light pole: The installation spacing is 20-25 meters. 8-meter-high solar street lights are suitable for secondary roads or small urban roads.
10-meter light pole: The installation spacing is 25-30 meters. 10-meter-high solar street lights are suitable for urban main roads or two-way lanes.
12-meter and above light poles: The installation spacing can reach 30-35 meters. This higher solar street light is suitable for wider roads or highways.
The above values are reference values, the installation spacing of solar powered LED street lights should be confirmed according to the actual situation. If it is at a crossroads or a special location with corner lights, even if the lamp pole height is high, the installation spacing of solar street lights needs to be appropriately reduced to ensure the lighting effect in these areas.
4. Light source power
The light source of solar street lights uses LED light sources with low energy consumption but high lighting efficiency. The light source power directly affects the lighting effect of solar street lights. If it is the same height, although the irradiation range is the same, but the power is different, the lighting efficiency will be very different. The lighting effect of low wattage is not as good as that of high power. At this time, you should consider shortening the installation distance of solar powered LED street lights and making them closer, which will improve the overall lighting effect.
The above are important factors affecting the installation spacing of solar street lights. In addition to these, the installation spacing of solar street lights is also affected by the installation environment and lighting demand factors. In short, determining the installation spacing of solar street lights requires comprehensive consideration of various factors.
If you cannot determine the installation spacing of your solar street lights, you can contact the manufacturer or supplier of solar street lights. They can provide you with more professional advice based on your needs and actual conditions. As a solar street lights manufacturer, we look forward to cooperating with you!
