Generic year 1990

By convention in PVsyst, all data which are not related to real weather data measurements of a given year are considered as a generic year, labeled as 1990.

This is the case for most of the monthly data in the database, which proceed from averages over several years.

This also holds for synthetic hourly data or Typical Meteorological Years ([TMY../tmy-typical-meteorological-year.mdmd)) or Design Reference Years ([DRY../tmy-typical-meteorological-year.mdmd)).
