Unlike TMY data, TRNSYS reads unmodified TMY2 data files. Department of Energy's Office of Solar Energy Conversion. The TMY2 data sets and manual were produced by the National Renewable Energy Laboratory's (NREL's) Analytic Studies Division under the Resource Assessment Program, which is funded and monitored by the U.S. TMY and TMY2 data sets cannot be used interchangeably because of differences in time (solar versus local), formats, elements, and units. As TMY2 data are based on more recent and accurate data and will make possible more accurate performance and economic analyses of energy systems, these data sets are recommended by NREL for use in place of earlier TMY data sets derived from the 1952-1975 SOLMET/ERSATZ data base.

The TMY2 data are derived from the 1961-1990 National Solar Radiation Data Base (NSRDB). National Renewable Energy Laboratory (NREL). Locations can be downloaded free of charge from from the U.S.
