PV glass & backsheets

Description

1. Product Overview

PV glass and backsheets are critical structural and protective components used in the manufacturing of photovoltaic (PV) solar modules. PV glass serves as the high-transparency front layer that maximizes solar radiation transmission while protecting the cells from environmental stress, while backsheets provide electrical insulation, moisture barriers, and mechanical durability at the rear of the module. Together, these materials ensure long-term performance, safety, and efficiency of solar panels operating in demanding outdoor conditions. As global solar installations accelerate, reliable PV glass and backsheet materials are strategically essential to achieving durable, high-efficiency solar power systems and reducing the levelized cost of energy (LCOE).
