Technical FAQs 4

Why do solar panels break a lot?

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.

Why is glass breakage a problem in solar power plants?

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.

Why do solar panels have glass?

Glass on solar panels protects the internal components, keeps out dirt and moisture, and maintains electrical insulation. Earlier, glass breakages were mostly due to clear causes. Impact due to hailstones, wind-blown debris, or even human-caused incidents like vandalism have been one of the common causes.
