Module reliability is facing a glass problem. Field and lab data show breakage rates that should make any EPC pause. And the kicker: “tempered” doesn’t always mean durable in PV.

🔍 20% of tested modules failed due to glass breakage; even simple outdoor stabilization saw 6 of 20 crack.

🧪 Thin glass can, in fact, be tempered—common assumption busted.

📏 “Tempered” spans multiple processes; not all meet PV durability needs.

Tristan Erion-Lorico and Teresa Barnes discuss PV module glass failures, thin-glass tempering, and much more on the latest episode of SunCast with Nico Johnson.
