32nd European Photovoltaic Solar Energy Conference and Exhibition; 2105-2109, This paper presents results from a high speed photovoltaic sweeper system measuring the IVcharacteristics once per second of a solar panel under test at the ESTER PV test laboratory at the Tor Vergata University in Rome and in Denmark. The high temporal resolution of the scans shows the detailed temperature characteristics of the primary panel parameters compared to the reference irradiation/spectral data obtained via the ESTER instrumentation. An analysis of the irradiance levels shows that the STC and NOCT conditions in real life are extremely rare events. Analysis show that the temperature coefficient is depending on the irradiance level.

Poly (ethylene-co-vinyl acetate) (EVA) is the major polymer used for photovoltaic (PV) modules encapsulation. Its degree of cross-linking (related to its gel content) is taken as a major quality reference. Differential Scanning Calorimetry (DSC) has been proven to be fast and effective but is to determine the gel content, however, destructive for the PV module. With the aim to develop a non-destructive quality assessment tool, a detailed discussion on the DSC thermogram of EVA PV encapsulant is presented here. A possible path towards a fast and non-destructive method for determing EVA gel content is proposed based on the DSC analysis.
