WG 2: Reliability and durability of PV

This WG’s Chair is dr. Jeffrey Kettle (University of Glasgow) and its Vice-Chair is dr. Mohammadreza Aghaei (NTNU).

  1. Definition of reliability and durability metrics for PV modules, components and systems
  2. Identification of relevant data to be collected to measure reliability and durability
  3. Development of a holistic approach of autonomous monitoring and analysis for reliability and durability of PV systems using the potential of big data bank and the methods of big data analytics (BDA).
  4. Sharing knowledge via workshops, seminars and joint publications originating from WG2 with a wider community of PV stakeholders and other experts working for insurers, investors and banks.


Task 2.1: Development of a common description of reliability and durability of PV modules and PV systems by meetings and communications with PV researchers and other experts leading to a shared document to be published on this COST Action’s website.

Task 2.2: Identification of required data and appropriate simulation models to be used in the framework of understanding reliability and durability given the challenges of (i) the often long elapsed duration before the occurrence of both defects and degradation of PV modules in the field (ii) the climate dependency of these effects and (iii) relationships between the manufactured quality of PV module and observed reliability and durability in practice.

Task 2.3: Development of a new concept for automating the monitoring procedure, real-time analysis, and decision-making of PV systems using the potential of the big data bank and the methods of big data analytics (BDA).


D5. Publications of findings originating from WG2 in high-impact journals, conference proceedings and a special issue of an international peer-reviewed journal.

D6. Reports of the WG2 activities (months 12, 24, 36, 48), including the organization of one workshop per year on reliability and durability of PV modules, components and systems.

D7. An open-source model for durability and reliability aspects of PV systems.
