Quick Answer Flexible panels weigh 70–80% less than rigid glass panels and require zero roof penetration — but rigid panels still win on efficiency and lifespan. For OEMs and retrofitters, the right choice depends on roof geometry, climate zone, and total cost of ownership. Use the six-dimension comparison below, then jump to a product line

VS Hail Resistance: ETFE vs. Glass In 2026, the hail resistance showdown favors ETFE over glass. Sungold’s composite technology utilizes elastic buffering to absorb high-velocity impacts that shatter rigid tempered glass. Lightweight, UV-stable, and durable, our ETFE panels ensure your off-grid power survives extreme weather. ETFE Layer Elastic / Bounces Back Tempered Glass Rigid /
