Overview of Temperature Sensors for Temperature Measurement of PV Modules

In this paper an overview of temperature sensors used for PV module temperature measurement is presented. Issues with contact temperature sensors, in the process of PV module temperature measurement, are explained in detail. Brief overview of related research is given, which includes analysis of measurement process and the presented results. Thorough research is conducted based on few commercially available temperature sensors, which include four contact and a single non-contact sensor. Measurement accuracy of all employed sensors was evaluated using a high-quality thermal imaging camera and the obtained measurement results are also presented.
