6 FAQs about [Reasons for the cracking of photovoltaic panel tempered glass]

What are glass defects in PV modules?

Glass defects in PV modules refer to cracked or broken glass layers that are caused by human factors or extreme weather such as hailstorms and high wind- or snow loads [ 21 ]. The majority of the glass defects arise due to human force during installation, maintenance and primarily during on-site transportation of the PV modules [ 22 ].

How do glass defects affect a PV system?

Glass defects impact the economic performance of a PV system in multiple ways. The most obvious effect is the potential (in)direct performance loss of PV modules, which results in reduced economic revenues. Secondly, PV modules that suffer from glass defects may no longer meet safety requirements, therefore these modules are replaced.

Can a glass breakage damage a PV module?

Glass breakage, without any extreme weather event or other obvious cause, is being reported on a small yet significant number of PV projects. This issue comes with the potential to damage PV module performance in the long term, or even cause safety hazards – and we will need to act fast to find both the cause and a practical solution.

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 ].

Does weathering damage glass PV modules?

In glass-glass PV modules the interlayer is often Polyolefin Elastomer (POE) encapsulant. Subsequent weathering of the encapsulant, such as the ingress of moisture, may decrease the strength of defected glass PV modules. This will reduce the lifetime of the module and cause corrosion of internal components [ 20 ].
