In terms of user experience, the brighter the light source, the further the distance between each light source at night. However, from an investor’s perspective, the fewer solar streetlights installed, the lower the investment. We can allocate funds to other investments. If we can balance these two objectives effectively, as manufacturers of solar streetlights, we need to place the lights reasonably.
Installation distance for 4m solar streetlights:
Firstly, the height of the streetlight is approximately 4 meters, and these lights are mostly installed in roadway areas. It is recommended that the layout distance between each solar streetlight should be around 8 meters. If the solar streetlights are too far apart, they will exceed the illumination range of two lights, leading to dark spots in areas that require lighting.
Furthermore, if the distance between solar streetlights is too close, it will not only increase the demand for lights but also cause waste in lighting.
Installation distance for 6m solar streetlights:
The height of the streetlight is about 6 meters, which is generally favored for rural roads, especially for newly constructed rural roads with a typical surface width of about 5 meters. Given that traffic flow on rural roads is usually low, a one-way interactive lighting arrangement is generally adopted, and it is recommended that the distance between solar streetlights should be approximately 15 meters, but not less than 15 meters.
For certain street corners, an additional streetlight should be installed to avoid lighting dead spots.
Installation distance for 8m solar streetlights:
According to the specifications outlined in the “Technical Conditions for Highway Lighting,” if the installation height of the streetlight pole is 8 meters, the distance between the lights should be between 25 to 30 meters, arranged alternately on both sides of the road. Typically, solar streetlights are installed on both sides in a staggered lighting pattern, especially where the road width is 10×15 meters.
Installation distance for 12m solar streetlights:
Based on the installation experience provided by solar streetlight manufacturers, if the road exceeds 15 meters, it is recommended to use symmetric light distribution on both sides. Generally, it is suggested that the longitudinal spacing for 12m solar streetlights should be 30×50 meters. Using a 60W split solar streetlight is a good option, while a 30W integrated solar streetlight is recommended to have a distance of 30 meters.
For the installation of solar streetlights, we have a density reference: we cannot install them too closely together, as this results in a perceivable dual point from a distance and serves no purpose, ultimately leading to resource wastage. If they are too far apart, it can create blind spots in illumination. In areas that require light, a lack of continuity is also deemed a failure, making experience extremely important.
