Then, during installation, a light, routine pressure causes a crack to spiderweb across a panel. The installer is blamed, schedules are delayed, and costs mount. The real culprit was a tiny, almost invisible flaw on the glass edge—a ticking time bomb set weeks or even months earlier at the. .
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 engineering and quality assurance at Clean Energy Associates (CEA), it starts with a few panels – then dozens, hundreds, even. .

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. With the trend towards double glass sided modules as seen in Bifacials, or TOPCon with double glass sided. .
Solar glass is designed to be tough. But under the wrong conditions, even tempered glass can crack, shatter, or fail—posing major risks to performance, safety, and reliability. In today’s post, let’s examine why solar glass breaks, what it causes, and how we can design against it. 🔍 Common Causes. .
In order to solve the problems of low efficiency, susceptibility to interference by human factors, and low detection accuracy during the detection of photovoltaic glass edge defects by traditional manual methods, this paper proposes an automatic detection method of photovoltaic glass edge defects.
