Daily Performance Comparison of PV Modules Operating in Maui

to better understand performance differences between PV technologies and locations to identify the impact of the environmental and operating conditions without complex modelling The performance ratio (PR) has been used to compare PV daily performance, but it does not provide enough information to understand the variability between modules and locations. Complex modelling tools predicting the instantaneous production of the PV module provide additional insights on energy rating if the module reference data set is available [1]. A PV test platform, commissioned on the island of Maui in February 2016, has been used to conduct a side-by-side comparison of 10 different PV modules. A new energy rating analysis is proposed to elucidate the performance differences between PV modules without complex modelling.
