Extensive testing validates reuse of 23-year-old second-life polycrystalline solar modules

Researchers in Brazil tested second-life polycrystalline PV modules for two years and found they retained 87–88% of their original power, with minimal degradation and stable performance. Despite strong sustainability and circular economy benefits, economic incentives remain limited due to the declining cost and short warranties of new state-of-the-art silicon PV modules.Researchers at the Federal University of Santa Catarina (UFSC) in Brazil hav…
