Solar structures typically require regular maintenance to ensure their efficient operation and long-term use. The maintenance of solar energy structures can help avoid damage and reduce the risk of energy production decline. Generally speaking, the maintenance frequency of solar structures depends on various factors, including geographical location, weather conditions, structure type, etc.

It is generally recommended to conduct the following regular inspections and maintenance:
Regular cleaning: Solar panels can affect their power generation efficiency due to dirt such as dust, leaves, bird droppings, etc. Cleaning solar panels can help improve efficiency.
System inspection: Regularly check whether the wires, cables, brackets and other components of the solar energy system are normal, whether they are loose or damaged.
Monitoring performance: Ensure the normal operation of the monitoring equipment of the solar energy system, timely detect and solve potential problems.
System testing: Regularly check the power generation of the solar energy system to confirm whether the power generation meets expectations.

The maintenance frequency can be determined according to the actual situation, but generally speaking, it is recommended to conduct a comprehensive maintenance inspection every 6 months to 1 year, and decide whether further repair or cleaning is needed based on the inspection results. Meanwhile, it is recommended to regularly observe the performance of the solar energy system and respond promptly to any abnormal situations.

Please note that this is a general recommendation, and the specific maintenance frequency may vary depending on factors such as the size, model, and location of the solar system. If you have a solar energy system, it is best to develop a specific maintenance plan based on the supplier's advice and guidance.
