In 1992, France deployed solar modules still provide 75.9% of their original power after 31 years, surpassing the promised performance degradation rate of less than 26%. A study conducted by Hespul tested dismantled panels to compare current output with initial values against manufacturers' promises.
- Study Conducted: Hespul in France carried out a test on decommissioned 1992 solar modules, revealing high performance longevity.
- Initial Promised Performance: Panels were expected to maintain less than 26% output drop over 25 years.
- Actual Outcome: Modules showed an average of 79.5% power after 31 years, exceeding the promised performance rate.
- Performance Degradation Rate Over Time: Annual decline was found to be 0.66% over three decades and 0.42% for panels from a recent study.
