pearlpv mapEU COST Action PEARL PV is an inclusive network of PV system researchers focused on “Performance and Reliability of Photovoltaic Systems: Evaluations of Large-Scale Monitoring Data”. A significant part of this project is based on the idea of sharing monitoring data in a European context.

Namely the aim of PEARL PV to improve the energy performance and reliability of photovoltaic (PV) solar energy systems in Europe leading to lower costs of electricity produced by PV systems by a higher energy yield, a longer life time eventually beyond the guaranteed 20 years as specified by manufacturers, and a reduction in the perceived risk in investments in PV projects. This will be achieved by analyzing data of the actual monitored long-term performance, defects and failures in PV systems installed all over Europe to quantitatively determine the absolute influences of components rated performance, key design of systems, installation, operation, maintenance practice, geographic location and weather factors on the performance, performance degradation over time and failure modes of these PV systems.

This workshop is of interest to you, if you want to evaluate PV system data and/or if you own PV monitoring data. Namely, PEARL PV aims at forming the largest-ever agglomeration of PV systems performance data in Europe. By that, experts can evaluate and compare PV system performance and, also, validate smart system evaluation methods and evidence-based simulation and design tools. A key part of this initiative is the PEARL PV CKAN database, to which you can contribute!

In this parallel event we aim to inform the EU PVSEC audience about how to use this CKAN database. The program of this session, hence, includes a keynote presentation, 3 short presentations and a short interactive workshop on the features of the CKAN database. Also access to PV monitoring data is given during the session.
