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.

Abstract
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.| File | Dimensione | Formato | |
