What Is The Typical Lifespan Of A Photovoltaic (PV) Mounting System?

The typical lifespan of a PV mounting system is around 25 years.

The main factors affecting the lifespan of a PV mounting system are as follows:

1. Material Quality: Mounting systems made of high-quality steel or aluminum alloy have better corrosion resistance and weather resistance, resulting in a longer lifespan. Poor material quality can easily lead to rust and corrosion, shortening the lifespan.

2. Surface Treatment: Good surface treatments, such as hot-dip galvanizing and powder coating, can enhance the corrosion resistance of the mounting system and extend its lifespan.

3. Installation Quality: Correct and standardized installation ensures the stability and safety of the mounting system, reducing damage caused by improper installation. Installation should strictly follow design requirements, ensuring the tightness and verticality of the mounting system.

4. Environmental Factors: Different operating environments also affect the lifespan of the mounting system. For example, in highly corrosive environments such as near the sea, the lifespan of the mounting system may be affected. In dry, inland areas, the lifespan is relatively longer.

To extend the lifespan of photovoltaic (PV) mounting systems, the following measures can be taken:

Select high-quality materials and products, ensuring their quality meets relevant standards.

Regularly inspect and maintain the systems to promptly identify and address any issues.

Apply anti-corrosion treatments to the systems, such as regularly applying anti-corrosion paint.

Strictly adhere to specifications during installation to ensure installation quality.
