Importing PAN files into PVsyst involves several steps and considerations. PAN files, which contain text-based specifications of photovoltaic modules, facilitate the exchange of module data between different programs. To initiate the import process in PVsyst, users should access the `File -> Import components` menu on the main screen. This triggers an analysis of the selected data source, which can be a directory or a compressed zip file. The data to be imported is displayed on the left panel, while the current workspace is shown on the right panel. Users can then proceed to import specific projects or components. When importing a PAN file, users can utilise the `Import PAN files` button under Actions in the database product view of the PV modules. This opens a file selection window, allowing users to choose the desired PAN files for import. It is important to verify the validity of the imported data using the tools provided by PVsyst, including tables and graphs, to ensure accuracy and reliability for further analysis.

What You'll Learn
Accessing the Import menu
To access the Import menu in PVsyst, follow these steps:
Firstly, open the PVsyst software and navigate to the main screen. From there, locate the "File" menu in the top menu bar. This is the central hub from which you can initiate the import process for projects and components.
Once you've accessed the "File" menu, select the "Import Components" option. This will trigger the software to begin analysing your data. The tool will present a clear visual representation of the data, with the data to be imported displayed on the left panel and your current workspace on the right panel. This makes it easy to understand the file states and make informed decisions about the import process.
When selecting the "Import Components" option, you will be given the choice to select a data source. This can be located in a directory or compressed as a zip file. If your specified folder ends with "PVsyst7.0_Data\" or "Data\" (the standard PVsyst user data name), the software will display all data inside this directory. However, if your folder does not end with these designations, the software will only analyse data at that level.
Additionally, when dealing with PAN files, which contain text-based specifications of photovoltaic modules, you can access the "Import PAN files" button. This button is located under the "Actions" section in the database product view of the PV modules. Clicking this button will open a file selection window, allowing you to choose the PAN files you wish to import.

Selecting a data source
To import PAN files into PVsyst, you need to select a data source. This can be done by going to the "File -> Import components" menu on the main screen. The data source can be a directory or a compressed zip file.
If the specified folder ends with PVsyst7.0_Data\ or Data\, (the standard PVsyst user data name), the dialog will display all data inside this directory. This includes any projects, components, and project-related files in the same directory. The tool will then detect the file types.
On the other hand, if the specified folder does not end with PVsyst7.0_Data\ or Data\, the dialog will only analyze data at that level. This means that you can have projects, components, and project-related files in the same directory, and PVsyst will detect the file types.
Once you've selected the data source, PVsyst will analyze the data and display a representation of the data to be imported on the left panel. Your current workspace will be shown on the right panel.
Another way to import PAN files is by accessing the "Import PAN files" button under "Actions" in the database product view of the PV modules. This will open a file selection window where you can choose the PAN files to import.

Analysing the data
Importing Measured Data
Firstly, you need to import the measured data using a programmable data interpreter. This interpreter supports various file formats, such as ASCII files with hourly or sub-hourly records. You can select the relevant measured variables that correspond with the simulation variables in PVsyst.
Understanding File States
File states provide critical information about the import process. By paying attention to these states, you can ensure that you are importing the correct data and avoid unintentionally overwriting existing information. The four possible file states are:
- FileName.Ext written in normal font: indicates the file has not been imported yet.
- FileName.Ext written on a grey background: signifies that the file is already imported into your current workspace.
- FileName.Ext* followed by a star: denotes that the file is imported but has different content.
- FileName.Ext written in italic font: indicates that a similar component is already defined in PVsyst's built-in database.
Verifying Data Validity
After importing the data, it is essential to verify its validity to ensure accuracy and reliability for further analysis. PVsyst offers a comprehensive set of tools for this purpose, including tables and graphs with hourly, daily, or monthly values. Specific graph types commonly used in PV data analysis, such as inverter efficiency graphs and input/output diagrams, are also available for validation.
Selecting Data Source
The next step is to select a data source for importing the PAN file. This can be a directory or a compressed zip file. If the specified folder ends with "PVsyst7.0_Data\" or "Data\" (the standard PVsyst user data name), the dialog will display all data inside this directory. Otherwise, the tool will only analyse data at that level, allowing you to have projects, components, and project-related files in the same directory.
By following these steps and considerations, you can effectively analyse the data when importing PAN files into PVsyst, ensuring a smooth and accurate data transfer process.

Choosing projects or components
To initiate the import process, access the "File -> Import components" menu on the main screen. This will open up a selection window where you can choose the desired data source, which can be a directory or a compressed zip file. Once you've selected the data source, PVsyst will analyse the data and present it visually, with the data to be imported on the left panel and your current workspace on the right panel.
When choosing projects or components to import, you have the flexibility to select specific elements within the project or component. You can use Ctrl+Click to select multiple elements for import. This allows you to import only the specific variants or components you need, rather than the entire project or all components. For projects, you can choose to import referenced files or overwrite existing files with the imported ones.
Additionally, when importing PAN files, which contain specifications of photovoltaic modules, you can access the "Import PAN files" button under "Actions" in the database product view of the PV modules. This will open a file selection window where you can choose the PAN files to import. The import window will display columns such as "Manufacturer from file" and "Manufacturer in database," allowing you to adjust these settings if needed.

Verifying data validity
To begin, users can import measured data using a programmable data interpreter, which supports various file formats, including ASCII files with hourly or sub-hourly records. This flexibility allows users to choose the relevant measured variables that align with the simulation variables in PVsyst.
Once the data is imported, PVsyst provides tools such as tables and graphs to visualise the data in hourly, daily, or monthly values. These visual representations enable users to verify the validity of the imported data by comparing it against expected values. Specific graphs commonly used in PV data analysis, such as inverter efficiency graphs, input/output diagrams, and normalised performance parameters, are also available for more detailed analysis.
Additionally, PVsyst allows for the elimination of break-down events in the measured data. These undesired records, which may indicate system or measurement equipment failures, can be selectively removed to obtain clean statistical indicators, such as mean bias and standard deviation, corresponding to the normal operation of the system.
When verifying data validity, it is also essential to define the system parameters accurately. This involves defining a project and variant parameters, introducing the real properties of the system, and ensuring they align with the imported data. By following these steps and utilising the tools provided by PVsyst, users can ensure the validity and accuracy of their imported data, facilitating reliable analysis and informed decision-making.
