Title: The Case for Custom TMYs: Examples Using the NSRDB: Preprint

Abstract

A typical meteorological year (TMY) essentially represents an hourly compilation of median months constructed using multiyear data sets. Although TMYs are generated from global horizontal irradiance, they are used in photovoltaic (PV) modeling for various plane-of-array (POA) representations. This paper demonstrates that a POA TMY generated with corresponding POA irradiance time-series information produces significantly different results than a POA TMY generated by transposing a TMY data set. In some months, the differences can be more than 3%. These results point to the need for generating TMYs using POA irradiance time series representing the orientation at which PV panels will be deployed.
