Some recent studies suggested that glass defects were more prominent in newer modules (less than 4 years of age) as compared to 20 year old modules, which may be attributed to the adoption of thinner glass sheets that are more susceptible to glass breakage . Figure 6.
Scientists and researchers at NREL, including Timothy Silverman and Elizabeth Palmiotti, are investigating early failure in dual-glass PV modules. Dual-glass PV modules are experiencing low-energy glass fracture at an alarming rate under expected conditions of use.
When modules were small, or when they had a single sheet of glass, 3.2-mm glass was common. But now, both thin-film and crystalline silicon double-glass modules almost always use glass thinner than 3.2 mm— usually just 2 mm—to reduce weight and material use (Zuboy et al. 2024).
A module might keep working after its glass breaks, but not safely and not for long. Glass breakage has always been a concern, but until recently, the cause has been obvious. Some glass always breaks into small pieces, in a pattern that shows a clear starting point.

It might be from a very hot fault inside the module, like a series arc or a shunt in a reverse-biased cell. Or it might be a defect introduced during manufacturing or installation. Broken glass seems to be

With the trend towards double glass sided modules as seen in Bifacials, or TOPCon with double glass sided construction, the changes in solar PV module design and materials mean
It''s not just about the module, it''s about the system it lives in. The promise of double-glass modules is real. Better longevity, better moisture protection, higher energy yields.
Module Failure Modes in the field have been divided into five categories for the company''s identification, tracking and warranty replacement purposes. Once a failed module is identified and classified a
Double-glass modules, with their performance in the face of salt mist, high temperatures and high humidity, have won the market''s favour. However, this trend is not without its risks.
