How high is the solar street light suitable for rural streets?

Through reasonable planning and scientific selection, the lighting effect and safety of rural streets can be effectively improved, creating a safer and more convenient environment for villagers to travel at night.

Many villages find it very difficult to choose the specifications and models of solar street lights, such as the height of the light pole, and the power of the LED lamp head... Some of the professional issues involved are indeed difficult for outsiders. Since it is a professional issue, of course, it still needs to be answered by authoritative organizations.

Relevant data exist for the height of street lights. Generally, there are the following conventional heights: The height of street lights on both sides of the national highway must not be less than 12 meters. The height of street lights on both sides of the city auxiliary road must not be less than 10 meters. The height of street lights on both sides of urban streets must not be less than 8 meters.

Through these data, we can infer that the higher the light pole, the wider the lighting area required, and the greater the power of the light source. So it can be seen that rural streets are usually narrow, the crowd flow at night is small and the activity time is short. If such venues are to install solar street lights, it is recommended that the height should not exceed 7 meters. This reason is supported by the following factors.

1. Configuration issues: As we said just now, the higher the light pole is, the greater the light source power is needed. Similarly, the lower the light pole is, the smaller the power source needed. For solar street lights, a small light source does not simply mean saving electricity, but it can reduce the configuration of the entire solar power generation system by one level. The price difference between low-end and high-end is very large. It is normal for a set to differ by three or five hundred. What if there are dozens or hundreds of sets? So this detailed account has to be calculated.

2. Maintenance/repair: Solar street lights, like other mechanical and electrical appliances, need maintenance. For example, if the environment of the installation site is very poor, it is often windy and dusty, and regular maintenance is required. For example, if it is used for half a year or a year, someone needs to go up and wipe off all the dust on the surface of the solar panel. If there is too much dust on the surface of the solar panel, it will seriously affect the light collection and eventually cause the battery to be in a long-term over-discharge state, resulting in a significant reduction in service life.

Solar street lights below 7 meters, especially 6 meters, have another special advantage, which is, easy maintenance. LED lamp heads are electronic components, and it is difficult to avoid problems. When problems occur, it is very easy to repair at a height of 6 meters, and a large ladder or two sets of scaffolding can easily solve them. However, higher street light poles do not have this advantage.

Through the above analysis and comparison, we can clearly see that for rural streets in towns, solar street lights below 7 meters are the best choice.
