Technical FAQs 4

How common are glass defects in solar panels?

The relative amount of glass defects ranges from several percent up to one of the most prominent failures of registered PV failures. A customer complaints research, on PV modules after two years of operation, observed glass breakage for 10% of the failure cases [ 28 ].

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 ].

Is solar glass breakage a problem?

module glass breakage has long been an observed failure mode in fielded solar projects. In recent years, however, the na ure and causes of solar glass fracture have changed in alarming and unsustainable ways. Given the scale of the global market, increasing solar glass failure rates have the potential to become

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.
