Abstract/Summary:


The Ciemat PV Laboratory usually performs I-V curve measurements of PV modules in order to determine their power and other related characteristic electrical parameters. This paper describes a procedure to perform the peak power control of large provisions of PV modules for big PV power plants. The proposed procedure includes the following steps: initial comparison of measurement results between manufacturer and laboratory considering a sample of at least 10 PV modules in order to check and calibrate power and verify measurement repeatability; sample selection from a given manufacturer batch; sample testing; modification of the manufacturer flash report data for the batch according to the testing results obtained for the sample in the laboratory; application of the conditions provided in the contract of sale signed between the PV module manufacturer and the owner of the PV plant according to the values given by the manufacturer and corrected by the laboratory results. In this work data corresponding to 6,333 PV modules, 140 models from 52 manufacturers, tested by the Ciemat PV laboratory during the last 18 months, are included.
