6 FAQs about [Photovoltaic glass testing]

Do glass-glass PV modules show defects?

The as-received glass-glass PV modules did not show any visible deficiencies and were used as reference during the test series. After the initial tests, the glass defect PV modules were divided into two subgroups: repaired specimen and non-repaired specimen.

Can glass-glass PV modules be repaired?

Testing of experimental glass repair technique for glass-glass PV modules. After damp-heat test repaired modules showed no signs of water ingress. Economic and ecological feasibility shown using Cost Priority Number metric. Solar photovoltaic (PV) energy is a crucial supply technology in the envisioned renewable energy system.

Are glass-glass PV modules safe?

Especially since glass defects arise more frequently at glass-glass PV modules [ 12, 13 ]. Glass defects can disrupt the insulation of the encapsulant layer and PV cells, which can lead to ingress of water. This affects the reliability of the PV modules and might cause safety and/or performance issues [ 11 ].

What is a glass-glass PV module?

A growing share of decommissioned PV modules will be glass-glass PV modules, these modules are different from regular glass-back sheet (GBS) modules and replace the traditional polymer back sheet with a glass layer identical to the top glass layer. Glass-glass PV modules currently account for about 15% market share in the PV industry.

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 ].

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.
