Importing ReuniWatt Data

Weather data files cannot be dowloaded from the website (ReuniWatt has to be contacted by mail, info@reuniwatt.com)

The hourly data is provided in the PVsyst standard format, for a direct and easy import in PVsyst.

Reference time of weather data files is GMT (universal time, UT).
