Pvsyst Software Is Designed

This software is designed for use by architects, engineers and researchers and is a very useful educational tool.

The program has a detailed contextual help menu that explains the methods and models used and provides a user-friendly, guided approach to developing a project.

PVsyst is able to import meteorological data from various sources and personal information.

However you can easily create your own components by yourself.

The easiest way is to choose a similar existing device in the database, modify its parameters according to the manufacturers datasheets, and save it under a new name, therefore creating a new file in your database.

For Crystalline modules, except Isc, Vco, Impp and Vmpp, nb of cells in series and module sizes, you can let all the other parameters (mainly Rserie, Rshunt, Rsh(0) and RshExp) at their default value.

You have a checkbox near to each parameter for retrieving the values proposed by PVsyst.

PVsyst simulation engine runs the simulation taking into account global horizontal irradiation, diffuse horizontal irradiation and temperature (and wind speed if available).

PVsyst users can proceed in two complementary ways when importing Solargis hourly data.

One option is using a Typical Meteorological Year (TMY) file, which summarizes weather conditions in one single year of hourly data.

Other option is using a Time series file, from which several separated one year periods for specific years can be created in PVsyst weather database.

Importing Solargis weather info contained in csv hourly files when working with PVsyst takes only few seconds (tested in version 6): Go through Databases - Import meteo data to open a dialog named Import meteo data from different sources.

After clicking on Import, PVsyst will create one hourly meteo file (.MET) for one-year period, which can be used when simulating designed systems.

When this is not the case, in Solargis we are also supporting older versions by providing csv files in Longitudinal Time Zone (LTZ) time reference, which is based on using longitudinal reference of the site as longitude15 (rounded value).

Data Time-step. Other time steps like sub-hourly or daily are also admitted in PVsyst.

Although importing such files is not so direct, it is possible through Databases - Import ASCII meteo file.

A dialog named Conversion of ASCII meteo sub-hourly files will be opened showing other customizable importing options.

This option is also suitable when using older data formats which are not supported anymore.

Data format. Although recent versions of PVsyst 6 support Solargis csv hourly format, some older versions of PVsyst only accept data in PVsyst Standard Format, which can be chosen from the drop-down box when importing data.

Solargis also supports this format for such cases when last versions of PVsyst are not available.

Some sites especially in tropical climate have a very high DIF which is out of PVsyst internal default limits.

Therefore, PVsyst will show this type of notification: The Clearness index of the best clear days is very low with respect to the clear day model.

For certain regions, Solargis full time series data file is starting in July 2006 (starting of operations of the satellite over Pacific region).

In this case, if a period from January to December is required, Solargis csv file needs to be adjusted by removing the first rows from 54 to 4469 (corresponding to dates from July to December 2006).

Before importing the data, the period should be also adjusted manually in rows 19 and 25 accordingly (01012007 instead of 01072006).
