Dual-glass TOPCon modules demand superior encapsulation to prevent moisture ingress and PID degradation. This technical guide examines POE and EPE encapsulants through the lens of recent UNSW research showing 55% power loss from poor formulations versus 6% from quality materials. Includes decision matrix for coastal, tropical, and desert installations, plus supplier verification criteria for HALS-based POE and tier-1 EPE.
