This paper conducts a state-of-the-art literature review to examine PV failures, their types, and their root causes based on the components of PV modules (from protective glass to junction box).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 ].
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 PV modules survive a glass defect?However, glass defects do not directly imply that PV modules endure internal damage nor that PV modules cannot continue to operate with minimal microcracks. Thus far, glass defects have been regarded as a failure beyond repair and no noticeable attempt has been made to develop reparation methods.
How common is glass breakage in PV modules?A customer complaints research, on PV modules after two years of operation, observed glass breakage for 10% of the failure cases [ 28 ]. Another study on PV failures observed an even higher failure-share for glass breakage.
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 ].
