Performance, Operation and Reliability of Photovoltaic Systems


Performance and reliability of PV modules and systems are key topics that are attracting more and more attention from various stakeholders every day. Recently, it also comes in combination with the terms of quality and sustainability.


The overall objectives of Task 13 are to:

  1. Gather the most up-to-date information from each member country on a variety of technical issues related to PV performance and reliability. This will include summaries of different practices from each country, experiences with a variety of PV technologies and system designs.
  2. Gather measured data from PV systems from around the world. This data will be used to test and compare data analysis methods for PV degradation, operation & monitoring (O&M), performance and yield estimation, etc.

Communicate to our stakeholders in a number of impactful ways including reports, workshops, webinars, and web content.


Task 13 aims at supporting market actors to improve the operation, the reliability and the quality of PV components and systems. Operational data of PV systems in different climate zones compiled within the project will allow conclusions on the reliability and on yield estimations. Furthermore, the qualification and lifetime characteristics of PV components and systems shall be analysed, and technological trends identified.



Task 13 has so far managed to create the right framework for the calculations of various parameters that can give an indication of quality of PV components and system. The framework is now there and can be used by the industry who has expressed in many ways appreciation towards the results included in the high-quality reports.


Task 13’s current phase began in 2018,ends in 2021 and activities are organized as follows

1 Subtask 1 New Module Concepts and System Designs

2 Subtask 2 Performance of Photovoltaic Systems

3 Subtask 3 Monitoring – Operation & Maintenance

4 Subtask 4 Information Dissemination
