Suitable Installation Distance for Solar Power Street Light

In recent years, the construction of new rural areas has been very hot. Many rural areas have installed solar street lights. In fact, solar power street lights are the first choice in rural areas. The installation distance of solar street lights is determined by width of the road, the height of light pole, power of light source, and the way of lighting. Generally, where solar power street lights are used, the distance is about 20 meters or 25 meters. If the distance is greater, the light between the two lights cannot be well connected. So how to determine the installation distance between solar power street lights? It can be considered from the following points:

1. Lighting method

Solar power street lights generally adopt the following three lighting methods when installing: single-sided lighting, cross lighting on both sides, and symmetric lighting on both sides. Special roads such as crossroads, T-shaped intersections and bends can be lighted according to the actual situation. If lighting is required for both motorized and non-motorized lanes, single-sided or two-sided two-way lighting can be used.

2. Height of the solar power street light pole

The height of the solar power street light directly affects the illumination range of the led lamps. The higher the light pole, the wider the illumination range according to the Pythagorean theorem. Scenic spots and parks are generally suitable for installing solar power street lights of about 7 meters, especially for new rural construction roads with a width of about 7 meters. In the night, the traffic of pedestrians and vehicles on rural roads is not large, so it is generally installed by one-sided interactive lighting, and the installation distance is about 20-25 meters. If it is less than 20 meters, part of the lighting will be affected. In addition, one more street light should be installed at the corner to avoid lighting blind spots.

If you want to install a solar power street light with a pole height of 8 meters, you must ensure that the distance between the street lights is 25-30 meters. You should use the cross-lighting method for installation on both sides. This method is mostly used for road lighting with a width of 10 -15 meters.

For roads with 12-meter light poles, the longitudinal spacing of solar power street lights is generally recommended to be 30-50 meters. Symmetrical lighting on both sides should be used, and the road lighting width needs to exceed 15 meters. 

3. LED light source power

The power of the LED light source will also affect the installation spacing of solar power street lights. If it is the same height, although the irradiation range is the same, but the power is different, the lighting efficiency is very different. The lighting effect of low wattage is not as good as that of high power. At this time, we must consider shortening the installation distance of solar power street lights and make them closer together, which will improve the overall lighting effect.

Installation in accordance with the above requirements can greatly ensure the road lighting requirements without causing waste of resources. If the solar power street lights are installed in close distance, it is unreasonable, which is easy to cause waste of resources, and the investment cost is relatively large. Of course, there are many kinds of solar power street lights, and there are also many options for configuration. We can't give suggestions one by one here. If you still don’t understand, you can also consult the professional solar power street light manufacturer, who can customize it according to the customer's situation.
