The lifespan of a solar panel is approximately several years

The service life of solar panels usually depends on a variety of factors, including material quality, production process, usage and maintenance, etc. Here is an overview of solar panel life:

1. Nominal life: The standard life of solar panels is generally between 20 and 30 years.

2. Material influence: The life of solar panels is closely related to their power generation efficiency. The degree of bonding of the PN junction and the purity of the silicon wafer determine the intensity of electrical energy generated by the solar panel under the same light. Over time, the PN junction can break down, resulting in a loss of efficiency. For example, the conversion efficiency may remain above 90% after 15 years, but may drop to around 80% after 25 years. 45

3. Maintenance and upkeep: The lifespan of solar panels also depends on their maintenance and upkeep. Regular inspection, maintenance and cleaning can extend its service life. 6

4. Different packaging materials: Solar panels with different packaging materials have different lifespans. For example, the life of tempered glass laminated solar panels can reach 25 years, while the life of PET laminated solar panels may be between 5 and 8 years.

To sum up, the life of solar panels is affected by many factors, and the actual service life may vary depending on use and maintenance. When choosing solar panels, it is recommended to consider their quality, materials and after-sales service provided by the manufacturer to ensure long-term economic and environmental benefits.
