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 ].

Do PV modules with glass defects meet safety and performance standards?

The probability of (in)direct degradation and electrical shocks by glass defects, make that PV modules with glass defects do not meet the safety and performance standards set by the International Electronical Committee (IEC 61215 and IEC 61730) [ 41] (see Appendix A for more details).

How thick is a glass-glass PV module?

2.2. Glass characteristics Glass-glass PV modules generally use 2–3 mm thick glass layers, since thicker glass layers negatively impact the module's weight and costs, while trends are to reduce glass thickness to below 2 mm [ 10 ].

What are custom-made PV modules?

Therefore, the case study made use of custom-made PV modules developed by DMEGC Solar and SolSolutions [ 43 ]. The PV modules have three distinctive characteristics: double glass for light passage, bifacial PV cells and extra thin glass (1.6 mm per layer).

What are the characteristics of PV modules?

The PV modules have three distinctive characteristics: double glass for light passage, bifacial PV cells and extra thin glass (1.6 mm per layer). The PV installation entails 4236 PV modules in strings of 24 PV modules [ 44 ]. The usage of extra-thin glass enhanced the occurrence of glass (edge) breakage.

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 ].
