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.
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.
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.
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. Here, we summarize our observations and thoughts on PV glass breakage in utility-scale power plants.
