The hot string and the cool module: case study of fault detection in PV systems by means if IR photography

IR photography was used for the inspection of a PV system on the fa??ade of a building. The IR photographs showed five PV modules having a temperature that was significantly higher than that of neighbouring modules. The open-circuit voltage and short-circuit current of the strings in the PV array were measured. It was concluded that a single...

Characterisation of PV modules of new generations: results of tests and simulations

PV modules of nine different types were tested during indoor and outdoormeasurements. The electronic and thermal properties of the modules were determined and in simulations the energy yield of these modules under typical Dutch meteorological circumstances was calculated. 2 refs.
