Assessment of the adequacy of EN ISO 15927-4 reference years for photovoltaic systems

The long-term performance prediction of photovoltaic systems requires representative meteorological data from a particular location. Among the numerous proposals in the field of solar energy, most of them include procedures oriented towards the generation of test reference years (TRYs). These synthe...
