The Meteonorm program
(V7.1, fully included in PVsyst V6) holds measured meteo data for about 1'500 sites in the world, named "Stations
" (10-30 years monthly averages, in the range 1980-2010).
But it allows also to get meteo data for any location
on the earth, either by interpolation (between the 3 nearest stations), or on the basis of satellite data when no sufficiently near site is available.
The "native" database present in Pvsyst is based on these 1'500 Meteonorm measuring "stations".
However in the PVsyst "Databases > Geographical sites
" option, you can choose any location on a google map
(or simply by specifying the coordinates), and get meteo data for this location either from Meteonorm or from the NASA-SSE database. Please see the post below for the procedure.
Therefore even if you don't see your country
in the database list, it will be present after you will have defined a site for your location.
Now you have tools in the software for easily importing data from many well-known irradiation databases:
(whole earth), Satellight
(Europe and Africa), Nasa-SSE
(whole earth), Soda-Helioclim, Retscreen
, NREL TMY3
in the US, EPW
in Canada, NREL(TMY3)
for India, etc.
For this, please open "Databases
" / "Import Meteo Data
", choose the source, and press F1 for more details in the Help, a description of each source and the procedure for importing them.
If you can obtain climate data from your Meteorological Service, of if you have your own measured data
, you have also a general tool for importing data from almost any ASCII (text) file
Now there are several companies which distribute Satellite recent data for anywhere on the earth: e.g. SolarGIS
. They avail of recent data in hourly values
, but this is for pay
You can also import these data readily into PVsyst using "Databases" / "Import Meteo data".
NB: when you have Meteo data in Monthly values, you have to generate a synthetic hourly file
for using them in the simulation.
