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. This change of thickness affects multiple risk factors for breakage, as we describe below. Not from hail or mishandling, but from cracks that spider from frame edges, splinter near clamps, and web across modules. In cases seen by Jörg Althaus, director of. . We have seen cases of the glass in solar panels (photovoltaic [PV] modules) breaking differently, and more often, than it did 5 years ago. These breakages are not caused by hail, dropped tools or obvious mishandling. This issue was highlighted in its annual PV Module Index, which looked at emerging issues in solar glass manufacturing and field performance.
