As operations and maintenance technicians and forensic investigators know all too well, PV modules have always been susceptible to brittle fracture. For several decades, the root causes of solar glass breakage in the field were generally readily apparent based on an analysis of fracture patterns and failure distributions.
Modern PV modules often use thinner glass to reduce weight and material costs which lead to glass breakage. Glass breakage is a growing concern for the solar power plant operators.
Based on typical breakage patterns, researchers at NREL have noted that standard 3.2-mm solar glass appears to functionally meet the threshold for fully tempered safety glass, meaning it tends to break into relatively small and harmless fragments .
We have seen cases of the glass in solar panels (photovoltaic [PV] modules) breaking differently, and more often, than it did 5 years ago. There have been many changes to PV module design and materials in that time. Several changes have increased the risk of glass breakage. But there is probably no single change that is responsible for the problem.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
