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.

Is spontaneous PV module glass breakage increasing?

Yes, the sixth annual PV Module Index Report from RETC had some troubling findings, headlined by reports that spontaneous module glass breakage in fielded projects is increasing. That is glass breakage — for no apparent reason — often before commissioning.

Are glass-glass PV modules a problem?

Unfortunately, glass-glass PV modules are, similar to regular PV modules, subject to early life failures. A failure of growing concern are defects in the glass layer (s) of PV modules. The scale of decommissioned PV modules with glass defects will increase with the development of solar PV energy [ 7 ].

Why does my PV module glass break?

Broken glass seems to be more common than before. In the past few years, our team has found power plants around the world where PV module glass has broken with no obvious cause. We call this type of breakage spontaneous.
