What is the general lifespan of a solar PV system?

The general lifespan of a solar PV system is typically around 25 to 30 years. This duration reflects the expected performance and durability of the components involved, particularly the solar panels, which are designed to maintain a significant level of efficiency over that period.

Most manufacturers provide warranties for solar panels that often guarantee performance for 25 years, indicating that they expect the panels to produce a substantial percentage of their original capacity (commonly around 80% or more) by the end of that time frame. While other components of the solar system, such as inverters, may have shorter lifespans, the overall system is built to last for decades with proper maintenance and care.

The other options suggest shorter lifespans which do not align with the longevity typically associated with modern solar technology and materials. Solar PV systems are engineered to be reliable and have a long operational life, making the 25 to 30 year timeframe the most accurate reflection of their durability.
