Australian researchers develop automated screening method for second-life PV modules

An automated I-V screening method identified 58.1% of decommissioned PV modules as suitable for second-life use, with those passing the screening showing a median estimated residual useful life of around 12 years. However, about 14% of modules that passed combined I-V and EL screening failed wet-leakage tests, highlighting the need to assess insulation safety separately from performance.
