6 FAQs about [Analysis of the defective phenomenon of double glass in photovoltaic panels]

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.

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 ].

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 glass defect reparation damage PV cells?

Furthermore, the research analyzed the economic and energetic impact of glass defect reparation in comparison with regular substitution. We found that glass-glass PV modules which endured glass defects did not show performance loss, nor internal damage to the PV cells.

What is a double glass PV module?

Double-glass PV modules In double-glass or glass-glass PV modules the polymer back sheet layer is replaced by a glass layer identical to the top glass, creating a symmetrical “sandwich” structure. The PV cells are in the center, compressed by an encapsulant film and glass layers [ 11 ].

How much energy does a double-glass PV panel use?

The double-glass PV specimen has an invested energy of 1633 kWh/per module (986 kWh/m 2) [ 63 ], whereas the invested energy for the glass repair resin is calculated at 1.51 kWh/per module reparation [ 63 ]. Obviously, the do-nothing alternative does not require any energy investments.
