press-release - industry experts assess status of solar plant performance - 17 septembre 2015
As outlined in the current implementation plan of the Solar Europe Industry Initiative, the
photovoltaic (PV) industry is committed to improving the long-term performance of
connected plants. This requires important efforts along the whole value chain, from
material and hardware production to operation and maintenance.
Today, at a conference organised by the European Photovoltaic Technology Platform,
and moderated by SolarPower Europe advisor Thomas Doering, distinguished industry
experts shared their views on strategies and instruments to predict, monitor and improve
the performance of PV plants.
Al specialists agreed on the paramount importance of comprehensive, granular and
reliable data for conducting robust analyses of connected plants. Industry strategies and
instruments to improve data mining are numerous: Dr. Nicolas Sébastien, Chief
Technology Officer, Reuniwatt described the benefits of combining ground
measurement and satellite data, while Jeanna Panel a, Team Leader Performance
Engineering Group, First Solar stressed the necessity of advanced analytical software tools
and algorithms.
The experts concurred that the quality of materials and of modules, beyond the existing
industry standards, makes a great difference with respect to the long-term performance
of PV plants. Dr. Lucie Garreau-Iles, Technical Manager EMEA, DuPont Photovoltaic
Solutions explained that the quality of backsheets is vital y important, as it can impact the
long-term durability and reliability of solar systems. Juan Carlos Gonzalez, Senior Technical
Manager EU pointed out that his company Jinko Solar has adopted several strategies to
improve module performance and reliability, selecting the appropriate BOMs through a
program of tests beyond the standards and introducing a new optimizer for the
avoidance of hotspots offering 3 MPPT per module.
Another question answered was: What happens when modules fail? Christoph Reiners,
Head of O&M, BayWa r.e. outlined several replacement strategies. These depend both
on costs and on the legal framework, the latter requiring some clarification in many
European countries.
Commenting on the recently issued IEA PVPS Task 13 report on performance and reliability
described by Dr. Wilfried van Sark, Associate Professor at the Utrecht University, the experts
agreed that smart prevention, detection and classification of failures of PV plants wil
continue to be a majorfocus of PV research.
