2nd Module Workshop

3 February 2015 – Emmerthal, Germany

2nd Workshop

Impact of mechanical and thermal loads on the long term stability of PV modules

The Institute of Structural Analysis (ISD) at the Gottfried Wilhelm Leibniz Universität Hannover and the Institute for Solar Energy Research Hamelin (ISFH) organized the workshop “Impact of mechanical and thermal loads on the long term stability of PV modules” on th 3^rd February 2015 at ISD.

The main focus of this workshop is on mechanical and electrical characterization as well as on simulation of the behavior of PV modules. Both are imperative to understand power degradation of PV modules and to increase reliability. Invited speakers from research gave an overview of their current work.
