Solar manufacturing is facing a downturn, with analysts predicting that manufacturers will struggle to break even and may damage solar project warranties. The article suggests that manufacturers need to address issues of module quality to protect revenue, extend product lifetimes, and eliminate warranty-claim inefficiency. Technical testing is essential for project owners, with certified third parties contracted to test PV modules at manufacturer factories or ISO 17025-accredited laboratories. Sample testing is typically based on ISO 2859-1 standards that use the acceptable quality limit (AQL) methodology. Additional tests or inspections during construction might also include electroluminescence (EL) testing after delivery or installation, and potential-induced degradation testing.
