Combining Indoor and Outdoor Measurements to Lower Uncertainty in PV Modules Performance

In this manuscript, we present an overview of our module self-reference (MSR) calibration results of PV electrical performance collected for over three years on a silicon module. Analysis and comparison of the results based on measurement uncertainty analysis enable the quantification of the major sources of uncertainty and an estimate of the total uncertainty of the MSR measurements. The control charts show that the mean values are consistent with uncertainty calculations for P
