The lifespan of solar brackets is mainly affected by multiple factors, including material quality, design, installation quality, environmental conditions, etc. Generally speaking, high-quality solar brackets can be used for more than 25 years.

Solar brackets are usually made of weather resistant materials such as aluminum alloy, stainless steel, or galvanized steel, which have antioxidant and corrosion-resistant properties and can be used for a long time in outdoor environments. In addition, the design and installation quality of the bracket will directly affect its service life. If the bracket is designed reasonably, installed firmly, and well maintained, it can ensure its normal operation and extend its service life.

It should be noted that although most components of the solar bracket can last for a long time, some vulnerable parts, such as connectors and seals, may require regular replacement and maintenance. In addition, under certain environmental conditions, such as coastal or high-altitude areas, the lifespan of the bracket may be slightly shortened due to environmental corrosion or harsh weather conditions.

Overall, with reasonable material selection, high-quality design and installation, regular maintenance and upkeep, the lifespan of solar brackets can reach 25 years or even longer.
