The maintenance knowledge of solar street lights can be summarized as follows:

1. Maintenance of solar panels

Regular inspection: Solar panels should be regularly checked for integrity and for any damage or cracks on the surface. At the same time, it is necessary to ensure that there are no obstructions on the battery board to avoid affecting the photoelectric conversion efficiency.

Cleaning and maintenance: Solar panels should be regularly cleaned to ensure their surface transparency. When cleaning, gently wipe the surface of the battery board with a soft cloth to avoid using sharp objects or corrosive cleaning agents to prevent damage to the battery board.

2. Maintenance of batteries

Regular inspection: The battery's power and voltage should be checked regularly to ensure that it is in normal working condition. If insufficient battery or abnormal voltage is found, it should be charged or replaced in a timely manner.

Waterproof and moisture-proof: Batteries should be installed in a waterproof and moisture-proof environment to avoid damage to the circuit due to moisture, which can affect the lifespan and effectiveness of the battery.

3. Maintenance of lighting fixtures and circuit systems

Regular inspection of lighting fixtures: Regular inspections should be conducted to ensure that the lighting fixtures are in good condition and functioning properly. If any damage or abnormal lighting is found, it should be replaced or repaired in a timely manner.

Check the circuit system: Regularly check whether the circuit system is intact and whether the wires are aging or damaged. If there are any problems, the wires should be repaired or replaced in a timely manner to ensure the safety and stability of the circuit system.

4. Other precautions

Lightning protection: Solar street lights should be equipped with lightning protection facilities to prevent damage caused by lightning strikes.

Regular inspection: Solar street lights should be inspected regularly to promptly address any issues to ensure their normal operation.

In summary, the maintenance of solar street lights mainly includes the maintenance of solar panels, batteries, lighting fixtures and circuit systems, as well as other precautions. Regular inspections and maintenance can ensure the normal operation of solar street lights, extend their service life, and provide better lighting services for people.
