Generation of typical meteorological year data sets for 20 stations in Thailand

In this work a typical meteorological year (TMY) data sets for 20 solar radiation monitoring stations in Thailand were generated by using the Sandia National Laboratory method. A 10-year period of hourly global solar radiation, air temperature, relative humidity and wind speed from these stations were used to generate the TMY data sets. To investigate their performance, the TMY data sets were employed as input data of the TRNSYS simulation program to simulate photovoltaic systems. The electricity production calculated using the TMY data sets were in good agreement with those computed employing the 10-year period hourly meteorological data.
