Understanding and preventing PV module glass fracture
VDE Americas'' David Devir looks at the origins of the supersized PV glass problem and considers how the industry can return to reliability.
This report is available at no cost from the National Renewable Energy Laboratory at there is often no link to severe weather or an impact event. Most PV modules in power plants now use two pieces of glass. When modules were small, or when they had a single sheet of glass, 3.2-mm glass was common.
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.
Studies have found that contact between glass and frames is linked to spontaneous breakage in some PV modules. A recommended solution is using rubbery silicone spacers which maintain separation between the glass and the frame. Many modules already use silicone gaskets, but some designs leave gaps where the glass directly touches the metal frame.
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.
