Implication

Long-term experimental evaluation demonstrates minimal performance decay in polycrystalline silicon photovoltaic modules, indicating exceptional long-term reliability.

Key Points

Evaluate the long-term electrical performance, degradation mechanisms, and reliability of polycrystalline silicon photovoltaic modules following nearly 20 years of continuous outdoor exposure.
Tested an array of N=70 polycrystalline silicon photovoltaic modules from the same manufacturer after nearly 20 years of continuous outdoor exposure at the European Solar Test Installation.
Conducted comprehensive indoor electrical performance measurements (including current-voltage characteristics) and detailed visual inspections, comparing final metrics against initial baseline data.
Photovoltaic modules exhibited an average performance decay of 4.42% across the entire 20-year exposure period.
Analysis of specific degradation mechanisms confirmed sustained device reliability and structural integrity without catastrophic failure over multi-decade operation.
