Quality Roundtable @ Intersolar Europe 2018



Quality in procurement, installation and O&M 

pv magazine Quality Roundtable at Intersolar Europe 2018

The 9th pv magazine Quality Roundtable will take place at this year’s Intersolar Europe, on June 21. Combining the most successful concepts from our previous events, the first session will see industry experts and the audience discussing two case studies on poor quality in the field. Focusing on backsheet cracking and compensation after hailstorm damage, the discussion will revolve around how to detect faults; how to manage them; and how to evaluate with whom the responsibility lies.

How can data analysis help asset owners and operators increase their returns on investment? This question will be posed during the second session, which will examine one of the industry’s hottest topics: big data.

A thorn in the side of EPCs and investors in recent years, the issues of potential induced degradation (PID) and light induced degradation (LID) keep raising their heads. We believe they should no longer be relevant; although some are quick to disagree. The second session will, thus, also debate whether or not they really have been solved. Can we finally move on?


10:00 11:10 Session 1: Stop the blame game – Known and unknown examples of poor quality in operational installations

Case 1: Faulty backsheet

  • Discussion on the impact of faulty backsheets, and with whom the responsibility lies (in collaboration with Jay Lin, PV Guider)
    Expert input: Latest amendment of IEC 61730 and its impact on back sheet quality assurance (Jörg Althaus, TÜV Rheinland)
    Download the presentation of Jörg Althaus

Case 2: Unregulated damages after a hailstorm

  • Discussion on the impact of damages, which are visible, but which do not lead to an immediate loss of power
  • Expert input: EL image interpretation (Marc Köntges, ISFH, and Mischa Paterna, Suncycle)
  • Expert input: Legal background for the regulation of such issues with insurance

Invited experts

Dr. Lucie Garreau,
Technical Regional Manager, EMEA
DuPont Photovoltaic Solutions

“Five years ago, DuPont began raising awareness in the PV industry about the paramount importance that materials play in the durability and reliability of solar panels.  As our global field survey statistics mount, we see yet more and more material failures which compel us to reiterate with even more certainty, backed by over 1GW of data, that the right choices should be made to protect solar investments for the long-term.”

Dr. Matthew House
Strategic Account Manager
DuPont Photovoltaic Solutions

Matthew House joined DuPont 9 years ago, holding a variety of positions across R&D, production operations, quality control, marketing and sales. Industries served have included microcircuits, automotive, biomedical and aircraft. Photovoltaics has been a constant theme of his time in DuPont beginning with membership of the development team for the Solamet(R) PV16X range, with connections to all further generations through to the recently launched Solamet(R) PV21X, helping customers drive efficiency enhancements.


George Touloupas 
Director of Technology and Quality

“After accumulating 25 GW of track record in the PV industry performing quality assurance and production monitoring of PV components, CEA is now focusing into lab and field testing of PV modules. In partnership with pv magazine, CEA has developed a test program as a platform to gain insights into novel approaches to benchmark testing for the performance and reliability of modules, with the ultimate goal of helping investors make the right choices.”


Carlos Magistris 
Business Development Director and Principal Engineer 

“As we all know, only in the last 10 years, the photovoltaic sector has undergone drastic changes. In such a short time, we have gone through new materials, technologies and manufacturing processes. All of this, together with a spectacular reduction in prices and an increase in production capacity. Undoubtedly, all these changes have a direct influence on the quality and reliability of the products we use, and we must never forget that a photovoltaic plant should last up to 25 years. In consequence, both product quality and customer service are key tools.

At CEA, our commitment is to help our clients to deploy quality and, with this, help this industry reach levels of excellence.”
