The aim of this study is to evaluate and compare different temperature measurement methods of PV
modules. For that reason a special multicrystalline silicon PV module was laminated together with several PT1000
temperature sensors attached directly on the back surface of solar cells for reference temperature measurement. On the
back side of the PV module different temperature sensors were attached. The PV module was mounted at outdoor
conditions and monitored for several days. On the basis of measurement results deviations due to different temperature
sensors and methods are investigated. The thermal behavior of the sensors and influences of other factors are discussed.
Optimal sensor type and mounting technique is proposed in the light of its accuracy and applicability for simultaneous
temperature measurement of several PV modules for long term monitoring at outdoor conditions.
