How to calculate the engineering quantity of solar street lamps

The calculation of the number of solar street lamps mainly includes the following aspects:

1. Number of street lamps: First, determine the number of solar street lamps installed, which can be determined according to factors such as road length, road width, road type and lighting requirements.

2. Number of solar lamp posts: Determine the number of solar lamp posts installed according to the number of street lamps. Generally, each street lamp needs a lamppost.

3. Height of solar light pole: The height of solar light pole is determined according to road type and lighting requirements. Generally, the height of urban lampposts is 6- 12m, and that of rural lampposts is 4-8m.

4. Solar lamppost material: According to the height and use environment of solar lamppost, choose the appropriate material. Common materials are steel rod and aluminum rod.

5. Power of solar street lamp holder: The power of solar street lamp holder is determined according to lighting requirements and road types. Generally, the power of solar street lamp holders on urban roads is 30-100W, and that on rural roads is10-30W.

6. Power of solar street lamp board: According to the power of solar street lamp holder and the working time of solar street lamp, determine the power of solar street lamp board. Generally, the power of solar street lamp board is 1.5-2 times that of lamp holder.

7. Capacity of solar street lamp battery pack: Determine the capacity of solar street lamp battery pack according to the working time of solar street lamp and the power of solar street lamp board. Generally, the capacity of solar street lamp battery pack is 2-3 times that of panel power.

8. Power of solar street lamp controller: The power of solar street lamp controller is determined according to the working time of solar street lamp and the capacity of solar street lamp battery pack. The power of the general solar street lamp controller is 1.2- 1.5 times of the battery capacity.

9. Installation materials of solar street lamps: According to the number and height of solar lamp post, determine the materials required for the installation of solar street lamps, including bolts, nuts and welding materials.

10. Installation time of solar street lamps: The installation time of solar lamp post is determined according to the number and height of solar lamp post. Generally, the installation time of each solar lamppost is 2-4 hours.

Through the calculation of the above aspects, we can get the specific data of solar street lamp engineering quantity, so as to make the project budget and construction arrangement.
