This paper presents initial results from the first large-scale application of a measurement matrix-type energy yield prediction methodology (such as found in the IEC 61853-1 standard) to multiple photovoltaic technologies in a comparative assessment. The paper specifically reports on the modules of the first phase (of three) of the project. The methodology of the indoor characterisation and results of the first 4 module technologies are presented. These data are then applied to time series of weather data for a number of locations, demonstrating the quantification of site-to-site variation in operational efficiency of the different technologies. It is observed that even within technology families, there can be variation in annual specific energy yields of several percent. This is driven by differences that are identifiable from indoor measurements and thus the approach offers an efficient route to module selection for installations.
