Fault diagnosis of Photovoltaic Modules
The power drop of a PV module is typically defined between 80% and 70% of the systems initial power rating. Freire et al 6 reviewed the degradation modes by investigating on some PV modules with 10 years of activity. The most common failures in a PV module are laminate discoloration, isolation of cell parts due to cracks, and delamination.
A Review of Degradation and Reliability Analysis of a Solar PV Module
Affordability, Long-term warranty, scalability, as well as continuous decline in the LCOE (levelized cost of electricity) of PV (Photovoltaic) in many nations, are largely responsible for the current enormous up thrust in global installation of solar PV modules, at residential roof-top as well as utility-scale systems. Also, as the world''s energy portfolio evolves toward cleaner

6 FAQs about [Review of failures of photovoltaic modules]
What are the most common PV modules failures?
The most common PV modules are made of wafer-based silicon solar cells. Therefore a large knowledge base has been accumulated for the most PV module failures of this type. However even for this type of PV modules some effects like potential induced degradation and snail tracks have been studied in detail in the last 3 years for the first time.
What happens if a PV module fails?
The hotspot failure mechanism is considered the most severe failure and leads to catastrophic consequences. It deteriorates all PV module components if undetected, and a PV module affected by an elevated level of hotspots cannot reverse the degradation and often requires replacement.
Are PV module failure modes well described?
The literature review shows that PV module failure modes are well described in the literature, including their main driving factors. The review also shows that the right combination of the encapsulant and backsheet films can be beneficial in reducing failures.
How often do crystalline photovoltaic modules fail?
The rate is given relative to the total number of failures. Approximately 2% of the entire fleet are predicted to fail after 11-12 years (do not meet the manufacturer's warranty). Three typical failure scenarios for wafer-based crystalline photovoltaic modules are shown.
How to detect failures in PV modules?
There are basically three different types of thermography methods to detect failures in PV modules. The most common and easiest to apply technique is the thermography under steady state conditions. This method allows the analysis of PV modules in the field under working conditions.
What is a safety failure of a PV module?
Thereby, a failure of a PV module can be understood as the end of its lifetime based on reaching a threshold for the reduction in output power or because the operation of the module creates a safety hazard. According to IEA PVPS, a safety failure is any degradation or failure endangering on-site personnel or passers-by .
