Data Import Notice: As of the SolarAnywhere V3.8 launch, there is a known issue regarding the upload of SolarAnywhere files into PVsyst. Updates will also be provided on the PVsyst forum.

Impacted Versions

• 8/16/2014 UPDATE: Files downloaded after August 16, 2024 have updated column header names that allow for the correct import of wind speed values into PVsyst. No further action is required.
• ALL SolarAnywhere format files created since June 12, 2024 – August 16, 2024, are affected by this issue regardless of data version, TMY3 format files can still be uploaded as normal.
• This does not affect the API integration import method.

Quick Fix for Files Downloaded June 12, 2024 – August 16, 2024

• Existing files can be altered and uploaded to PVsyst by deleting the “Wind Speed 100m (m/s)” column header in row 2 from the meteo file before uploading. This will ensure that correct 10m Wind Speed is uploaded as opposed to 100m Windspeed (V3.8 files) or zero windspeed (V3.7 and earlier).

Resolution and Further Updates

• We are currently working on a fix with PVsyst and apologize for the inconvenience.
• For further questions please reach out to our Customer Success Team at support@solaranywhere.com.

Using SolarAnywhere Data in PVsyst

There are two ways to import SolarAnywhere® Data into PVsyst for use in PV production modeling:

1. Import the data directly into PVsyst using the SolarAnywhere API.
2. Download SolarAnywhere Data from data.solaranywhere.com, and import the file(s) into PVsyst.

Option 1 is only available to SolarAnywhere Typical Year Unlimited or Enterprise customers.

Import using the SolarAnywhere API

SolarAnywhere Typical Year Unlimited and Enterprise customers can take advantage of our PVsyst API integration by following these steps:

1. Generate an API Key or request an API key from the license manager of your SolarAnywhere Account.
2. Open the Geographical site parameters, new site dialogue box by selecting Databases from the home menu, then Geographical sites>New, or by starting a new Grid-connected or Stand-alone project and selecting the new site icon next to Site file.
3. Input the site coordinates within the Geographical Coordinates tab, or navigate to the site within the Interactive Map tab.
4. Select the SolarAnywhere® TGY bubble in the Meteo data Import menu, then select Import.
5. Input your SolarAnywhere API Key and select Okay.

Once an API key is used to import SolarAnywhere data into PVsyst, the key will be stored for future use. You can view or edit the stored API key by viewing the Network tab in the PVsyst Settings>Preferences menu. The following video demonstrates this import process.

Import a downloaded SolarAnywhere file

SolarAnywhere® typical-year or time-series data can easily be imported into PVsyst versions 6.85 and later by following a few simple steps:

1. Download typical-year or time-series data from SolarAnywhere in SolarAnywhere output format.
2. Open PVSyst and select Known Format under Import meteo data.
3. Select “SolarAnywhere (North America, Central Asia, Middle East 1998-today)” from the External Data Source drop-down menu.
4. Choose the SolarAnywhere typical-year or time-series file.
5. Select the correct Country and Region, or select “Get from coordinates” to let PVsyst complete this step for you.
6. Select Import.

The following video demonstrates this process and provides additional information about importing TMY3 format SolarAnywhere files into PVsyst.

Note that if you’re planning to use the relative humidity field in your PVsyst projects, download and import your SolarAnywhere data in the native SolarAnywhere format. While you can include relative humidity data in TMY3 format downloads, PVsyst cannot read this field when you import the data in this format.

Import a SolarAnywhere far-shading file

SolarAnywhere far-shading files may be imported manually into PVsyst by choosing the “Standard CSV file” option while specifying the direction of rotation of azimuth as clockwise and the north azimuth angle as 0 degrees (shown below):
