A broken solar panel can pose a serious risk, but the good news is that they don't break very often due to their ultra-durable construction and materials. Still, you should know the reasons why they break, how to help prevent breakages, and what to do if it happens. . Solar modules are getting bigger, thinner, and more powerful. But from Texas to Thailand, the same problem is appearing: broken glass. In cases seen by Jörg Althaus, director of. . This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. Tough Break: Many Factors Make Glass Breakage. . Scientists and researchers at NREL, including Timothy Silverman and Elizabeth Palmiotti, are investigating early failure in dual-glass PV modules. Photovoltaic (PV) modules require regular maintenance, so while solar is passive, you don't get to be. Close up of a solar glass breakage pattern on. .
