Ulrike Jahn

Job Title
Project Manager, R&D Projects
TÜV Rheinland Energy GmbH

Ulrike Jahn graduated in physics and leads various research & development projects in the business area of solar energy of the TÜV Rheinland Group in Cologne, Germany. Her work focuses on characterizing PV module technologies on one hand and on PV system performance analysis on the other hand. She is project manager of an international expert group, Task 13 of the PVPS programme of the International Energy Agency (IEA), dealing with technical and financial issues of PV performance and quality. She coordinates this network of 60 international experts in 23 countries in their joint efforts to assess and improve the performance, operation and reliability of PV systems over their lifetime. Since 2018, Ulrike is a Member of the Steering Committee of the European Technology and Innovation Platform for Photovoltaics (ETIP PV).

Data Driven Mitigation Measures in Advanced PV Plant Monitoring

Jul/20/2021 - 02:30 pm

ICM München, Room 12

In future, big data analysis using advanced AI techniques based on the monitoring of a large amount of data will enable the development of extensive benchmarking of key performance indicators (KPIs) for the solar PV industry. This will help PV developers to derive the real-life impact on the system losses and reliability of design choices and configuration during design phase, while O&amp;M operators could optimize their maintenance routines during the operational phase. The presentations in session 2 will cover the outcomes of the work carried out by IEA PVPS Task 13 experts to provide best practice on how to gain insights from monitored data and extreme diversity of asset types and operational context within a PV plant.</p> <br /><p>This session is jointly organized by Intersolar and IEA PVPS Task 13.


Performance of New System Designs

Jul/20/2021 - 11:30 am

ICM München, Room 12

Performance indicators for complex PV new systems have to consider their multiple-usage benefits. These PV systems are built to produce energy on the one hand and on the other hand to provide additional yield or benefits, economically or for instance regarding social acceptance of PV system installations. Thus, performance indicators besides energy yield related figures are relevant for rating a certain PV installation. This session attempts to provide a collection of new performance characterization methods for new PV system designs as a reference. New methods are described and explained by laboratory tests up to case studies. The presentations will cover the outcomes of the work carried out by IEA PVPS Task 13 experts to provide well-founded and comparable key figures in order to enable new PV system designs to move faster into new fields of PV applications.</p> <br /><p>This session is jointly organized by Intersolar and IEA PVPS Task 13.

Lindig (European Academy Bozen/Bolzano (EURAC) Research)



Sascha Lindig works as a researcher at EURAC in Bolzano/Italy, where he is currently completing his doctorate in cooperation with the University of Ljubljana/Slovenia as part of the H2020 Marie-Sklodowska-Curie Solar-Train project. His studies focus on statistical models for the quantification of the degradation of PV systems, degradation patterns and the economic evaluation of technical failures in PV systems. He first studied photovoltaic and semiconductor technologies at the University of Applied Sciences in Jena/Germany and then environmental and energy technologies at the HTWK Leipzig/Germany, where he received his Master of Engineering in 2014.
