Basically, certifications per se do not tell much about the quality of a module. If you buy a solar module with IEC 61215/ 61730/ 61701 etc. certifications, it means that the certification-holding manufacturer managed to produce a few modules of that type that passed a standard''s (e.g. IEC 61215) tests at the time of applying for certification.
PV module. The design qualification is deemed to represent the PV module''s performance capability under prolonged exposure to standard climates (defined in IEC 60721-2-1). In addition, there are several other standards (IEC 61730-1, IEC 61730-2 and UL1703) that address the safety qualifications for a module, but this area

The schematics in the Terminology section describe where each component is found on a common solar PV module. A Severity Rating is also defined to give users guidelines on how concerning a particular defect may be.
A solar PV module sample will be considered to be rejected due to its observable quality defects if any one of the following conditions are met: If any single observed defect has been evaluated as a Severity of 5. A Severity of 5 indicates a major quality issue; a critical failure or a fraudulent module.
Cameras-based monitoring PV modules are typically covered by a highly reflective glass sheet on the top of the solar cell, the thickness of which is around 3 mm . This has made possible to use various types of 2D cameras for their contactless monitoring.
However, under relatively relaxed environmental conditions, several researchers have successfully achieved accurate PV panels monitoring. For instance, in a diagnostic at PV cell level was suggested using IR scanning of a wide PV plant.
A 3 cm resolution camera is required for a typical PV comprehensive inspection to comply with the IEC thermography standard for detecting fine faults as well as their types. This is because of its ability to accurately measure the absolute temperature of the solar panels.
Where cells have become shiny or changed colour locally, cells have a poor or degrading anti-reflective coating which is an indicator of poor module performance. “IEC 61215: Crystalline silicon terrestrial photovoltaic (PV) modules - Design qualifications and type approval 2nd Edition,” International Electrotechnical Commission, Geneva, 2005.
