Technical FAQs 4

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.

Can glass break a PV module?

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.

Are solar modules Breaking Glass?

The pv magazine editorial team includes specialists in equipment supply, manufacturing, policy, markets, balance of systems, and EPC. Solar modules are getting bigger, thinner, and more powerful. But from Texas to Thailand, the same problem is appearing: broken glass.

How common is glass breakage in PV modules?

A customer complaints research, on PV modules after two years of operation, observed glass breakage for 10% of the failure cases [ 28 ]. Another study on PV failures observed an even higher failure-share for glass breakage.
