When all parameters are acceptable  (LED's all green or orange), the program gives access to the hourly simulation.

Simulation dates are based on the Meteo file dates, and can be restricted to a limited period.

The simulation process involves several dozens of variables, which are stored in monthly values in the results file, and will be available as monthly tables and graphs.

Nevertheless the program cannot store all these data in hourly values. Data of interest for the user should be defined before the simulation, in order to be accumulated during the simulation process. PVsyst offers three ways for the output of detailed hourly or daily data:

-        Accumulating Hourly values: the user may choose a set of variable of interest, to be accumulated in hourly values. Each variable will occupy about 18 kB on the output .VCi file. By default, the program chooses about ten fundamental variables. These will allow for displaying detailed plots of one or several simultaneously variables, with a very comfortable navigating tool over the whole year.

-        Special graphs: the user can pre-define four kinds of special graphs (time evolution, scatterplot, histogram and sorted values) for any variable in daily or hourly values. About ten specific and usual graphs are already defined with each new simulation.

-        ASCII export files: the user can choose any among the variables, to be written in daily or hourly values on an ASCII file for exporting to another software (spreadsheet, e.g. Microsoft Excel). The ASCII file is generated during the simulation process.

After completion, the simulation allows for opening the "Results" dialog.

Simulation results for a particular "variant" can be stored, with all involved parameters, in a file named as the project's file, with the extension .VCi  (i = 0..9, A..Z).
