2026, solar is now both critical infrastructure and a commoditized product, which makes quality differentiation paramount for long-term reliability, consistency and performance. Stakeholders require more confidence that the products being deployed today will continue performing reliably over decades, especially as new manufacturing scales rapidly and new materials and supply chains hastily enter the market.”
Based on testing conducted between Q2 of 2025 and Q1 of 2026, the 2026 PVMI evaluates PV modules using RETC’s extended real-world testing protocols designed to identify potential long-term reliability and performance risks that may not appear in standard certification testing. The report highlights several emerging trends shaping solar procurement, manufacturing and risk evaluation decisions across the industry.
