Solar Mount Daily Maintenance Guide: Keep PV Plants Stable and Extend Mount Service Life

As the global installed capacity of PV power plants continues to grow, solar mounts, as core supporting components of PV systems, are crucial for the stable long-term operation, power generation efficiency and revenue of power plants. Recently, industry technical experts have released a daily maintenance guide for solar mount systems based on different application scenarios and climate characteristics, providing scientific maintenance solutions for power plant operators to help extend the service life of mounts and reduce operation and maintenance costs.

In terms of maintenance cycles and key points, the guide clarifies differentiated requirements for different scenarios: For plain and rooftop PV power plants, it is necessary to inspect the fasteners of mounts every quarter, focusing on checking whether bolts and nuts are loose; if rust traces are found, special anti-rust coatings should be used for repair in a timely manner; for mountain PV power plants, due to complex terrain, the stability of the mount foundation should be inspected every six months to prevent mount tilt caused by soil settlement; for floating PV power plants, it is necessary to monitor the corrosion of underwater parts of mounts every month and regularly clean attached aquatic organisms to avoid uneven structural stress.

Regarding emergency maintenance after extreme weather, the guide puts forward specific operating specifications: After strong winds or heavy rains, priority should be given to checking whether the overall structure of the mount is deformed, focusing on the integrity of connectors and support beams; after snowfall in winter, snow on the surface of the mount should be cleared in a timely manner to prevent the mount from bending due to excessive snow weight, and at the same time, check whether there is freeze-thaw damage to components during the snow melting process. In addition, data records should be kept during maintenance, including mount tilt deviation and component wear, to provide a basis for the optimization of subsequent maintenance plans.

Industry experts said that scientific maintenance can extend the service life of solar mounts by 5-8 years and indirectly improve the stability of annual power generation of PV power plants. In the future, with the development of intelligent operation and maintenance technology, intelligent mount systems equipped with sensors will realize automatic fault early warning, further reducing manual maintenance costs and providing stronger support for the efficient operation of PV power plants.
