Measurements of thin film modules with a single flash inline simulator were compared to outdoor measurements with 6 different modules (2 a-Si, 2 CdTe and 2 CIGS). Outdoor measurements were done with voltage sweep times ranging from 0.5 to 25 ms. The performance of CdTe modules was measured before and after light soaking. Sweep time was not observed to have an effect on the measured performance with sweeps over 1 ms. Sweeps shorter than 1 ms can reduce the measured power particularly with a-Si modules. The differences with outdoor and indoor measurements were small implying the measurement is not sensitive to the used spectrum. The largest difference between indoor and outdoor performance was observed for triple junction a-Si.
