What preliminary work should be done to install solar street lamps?

Installation of solar street lamps requires the following preparations:

1. Determine the installation location: Before installing the solar street lamp, you need to carefully select the appropriate installation location. This position should be fully exposed to sunlight to ensure that the solar panel can fully absorb sunlight and convert it into electric energy. At the same time, the lighting range and safety of street lamps need to be considered.

2. Measurement of illumination: After determining the installation location, measure the illumination to determine the required solar panel and battery capacity. Illumination measurement is helpful to determine the lighting requirements of street lamps, as well as the specifications and capacities of solar panels and batteries.

3. Conduct power demand assessment: Before installing solar street lamps, it is necessary to assess the power demand of street lamps. This includes determining the power demand, lighting time and lighting mode of street lamps. According to these requirements, we can choose suitable solar panels and battery capacity.

4. Engineering design: After preliminary measurement and evaluation, engineering design is required. This includes designing the layout and installation mode of solar panels, designing the storage location and charging control system of batteries, and designing the installation mode and lighting control system of street lamps.

5. Purchasing equipment and materials: After the engineering design is completed, the required equipment and materials need to be purchased. This includes solar panels, batteries, controllers, lamps, cables and brackets. When purchasing, choose equipment and materials with reliable quality and stable performance.

6. Construction and installation: After purchasing equipment and materials, construction and installation can be carried out. This includes installing solar panels and batteries, installing controllers and lamps, laying cables and connecting wires, and debugging and testing the system.

7. Operation and maintenance: After installation, operation and maintenance are required. This includes regular inspection and cleaning of solar panels, inspection and replacement of batteries, inspection and maintenance of controllers and lamps, and regular inspection and maintenance of cables and connecting wires.

In a word, the installation of solar street lamps requires preliminary work such as illuminance measurement, power demand assessment, engineering design, equipment and material procurement, construction and installation, operation and maintenance. The completion of these tasks can ensure the normal operation and long-term stability of solar street lamps.
