The maintenance of ground solar brackets needs to pay attention to the following issues:

Regularly clean the solar panel and bracket structure to remove impurities such as dust, leaves, and dirt. This can improve the efficiency of solar panels and ensure the normal operation of the system. Soft brushes, water guns, or cleaning agents can be used for cleaning, but it is important to ensure safe operation and avoid damaging the surface of the battery panel.

Regularly check the installation of the solar bracket to ensure that the bolts are tightened and the bracket structure is firm. Especially in severe weather conditions, such as after a storm or rainstorm, more attention should be paid to inspection to prevent damage or instability.
  
Check the condition of the wires and connectors to ensure they are intact and undamaged. Excessive exposure to sunlight, temperature changes, and pressure may cause wire aging or connector loosening. If necessary, replace damaged wires or connectors to ensure smooth power transmission.

Ensure safety: Regularly inspect the safety situation around the bracket, including checking for any debris, damaged or inverted brackets, potential hazards, etc. Keep the area around the bracket clean and tidy to prevent accidents from occurring.

Regularly monitor the performance of solar panels, including power output and power generation. By monitoring system performance, problems can be identified in a timely manner and measures can be taken to fix them, ensuring efficient system operation.
  
In short, regular cleaning, inspection, and maintenance can help ensure the stability and efficient performance of the ground solar bracket system, and extend its service life. If encountering more complex maintenance issues, it is recommended to consult a professional solar system supplier or maintenance personnel.
