The lifespan of solar brackets is influenced by multiple factors, including bracket quality, material selection, installation quality, environmental conditions, and so on. Generally speaking, the expected lifespan of solar brackets can reach over 20 years.

Solar brackets are usually made of corrosion-resistant materials such as galvanized steel and aluminum alloy to resist oxidation and corrosion in outdoor environments. These materials have good durability and stability, and can be used under different climatic conditions.

In addition to material selection, the installation and maintenance of brackets also play an important role in their lifespan. During the installation process, it is necessary to ensure that the bracket is firmly connected to the solar panel and appropriate anti-corrosion measures are taken. In addition, regular inspection and maintenance of solar brackets are also important measures to extend their lifespan, including cleaning dust, tightening loose screws, and preventing corrosion.

It should be noted that even if built and maintained well, solar brackets will be affected by natural wear and accumulated fatigue over time. Therefore, in the design and investment of solar energy systems, the expected lifespan of the brackets should be considered and replaced or repaired as needed.
