Where it fits
Encapsulates and protects the delicate solar cells inside a finished module - low-iron tempered glass on the front, EVA film bonding the layers, and a backsheet sealing the rear.
Why it matters
A module is only as durable as its encapsulation - glass and EVA/backsheet quality directly determine a panel's 25-year degradation and warranty performance.
Where the value pool sits
Solar glass is a capital-intensive, scale-driven business prone to Chinese oversupply/dumping cycles that repeatedly squeeze domestic makers' margins; EVA/backsheet is more chemically specialised and still mostly import-dependent.
Key drivers
Module manufacturing capacity growth pulling through glass/EVA demand
Anti-dumping and safeguard duties on Chinese solar glass
