Thanks to the newly developed interface to software solutions of mounting system manufacturers, systems planned in PV*SOL® can be transferred to the manufacturer’s software. There, the system is designed according to the available mounting systems and the structural analysis. The finished mounting system planning can then be imported back into PV*SOL®, including the parts list and the report of the structural analysis.
The exchange between the programs is done with json and zip files:
If several module areas should be covered with modules with the mounting system software, steps 1. and 2.must be performed individually for each module area.
Supported mounting system software:
The precondition for using the interface is PV*SOL® premium 2023 R5 or newer, as well as an activated account for the planning tool of the mounting system manufacturer (only K2 Base so far).
The interface has been designed in a way that the user will get the fastest result with the following workflow.
First, the system is planned as usual in PV*SOL®, only without PV modules. It is important that the correct location has already been selected. Barrier objects and shading objects should also already be placed. Barred areas added in the mounting system software are currently not transferred to PV*SOL®. A module must specified but not yet placed on the module area. The modules are placed later in the mounting system program.
Once these steps have been completed, the export dialogue can be opened via the button Export to mounting system program .
Regardless of whether you were previously in the module coverage or module mounting tab, the same export dialogue will open in both cases:
If no module has been specified yet, this can be done here by clicking on New Module to the right of the first drop-down list. The storage directory for the export as well as the import of projects is the download directory. If desired, it can be changed by clicking on the folder icon.
The file name is composed of the project name, the name of the 3D object (e.g. building), an exclusive designation of the roof and the addition " - from PVSOL". The filename can be changed. However, this is not recommended so that PV*SOL® can automatically select the zip file to import later. In order to easily distinguish between the export and import files, the import file (zip file) has the addition " - from [name of the mounting system manufacturer]" (only K2 Base so far). Next, the desired mounting system manufacturer can be selected (only K2 Base so far).
If barred areas and shading objects have been placed and a module has been specified, the corresponding points should all have a green tick and you can continue with the Export button. This is also possible if no barred areas and shading objects have been created.
To make it easier to import the project back to PV*SOL later, do not make any changes to your PV*SOL project from now until after the import.
To continue with the selection of the mounting system and the coveage you first need access to the mounting system software.
K2 Base will now ask you for data on the loads and structural analysis. In the following, only the essential steps of planning are described, which are necessary to obtain a zip file that can be imported back into PV*SOL® afterwards. If you have questions about the K2 Base software, you can find the FAQs provided by K2 on https://k2-systems.com/en/faq-category/k2-base-en/. For further questions about K2 Base, please email base@k2-systems.de.
Please note the following points when planning in K2 Base:
If you are at a different location in PV*SOL®, activate the module area again (right click on the area -> Activate) that you had activated in the previous step during export and go to the tab Module Coverage or Module Mounting
Now click on the button Mountingsystem Import to open the import dialogue. If you have used your download directory for the export and import and have not made any changes to the file name, PV*SOL® will automatically find the zip file to be imported. Check that the correct manufacturer is selected in the drop-down list (currently there is only K2 Base). If this is the case, you can start the import by clicking on Import.
If you have selected a directory other than the download directory, you have the option to navigate to the location you have selected by clicking on the first folder symbol in the dialogue.
If you have changed the name of the import zip file, you can enter the name of the file in the input field or select it by clicking on the folder symbol to the right of the input field.* If the edge distances have been changed in the mounting system software, a message appears during the import process asking whether you want to accept the changed distances.
Please note that after importing, the arrangement of the PV modules should no longer be changed, otherwise the manufacturer’s structural analysis will become invalid. Modifications result in the removal of all elements of the mounting system from the roof. Only one zip file can be imported per module area
In this example, an east-west system is planned on two module areas. The example is limited to the steps concerning the mounting system interface.
Switch to the Design tab and select, for example, the following configuration:
Click on Add to automatically cover the entire roof. If you want to remove individual modules, you will find a description in the next section under the heading Remove modules (optional).
Switch to the Results tab and then directly to the Summary tab.
Download the mounting system zip file by clicking on K2+ PVSOL-Export.
Remove Modules (Optional)
To remove e.g. heavily shaded modules, you can proceed as follows:
In this example, the entire auto covered module area was imported into PV*SOL and the shade frequency was determined under Module Configuration -> Start Shade Frequency. Afterwards, K2 Base was opened again, frequently shadowed modules were removed there and the changed K2 Base project were imported into PV*SOL a second time.
Load the second module area (json file ending in from PVSOL.json) via Dashboard -> Open Project from K2+ -> PV*SOL into K2 Base.
Select the terrain category you chose for the first module area and click Next.
Accept the detected roof type and the roof covering with the button Create roof.
Switch to the Design tab and select the same configuration as for the first module area. for example:
Click on Add to automatically cover the entire roof.
Switch to the Results tab and then directly to the Summary tab.
Download the mounting system zip file by clicking on K2+ PVSOL-Export.
The plant should now be correctly placed on the roof. It can be configured as usual and then simulated.
In order not to invalidate the structural analysis created by K2 Base, the arrangement of the PV modules must not be changed after the import to PV*SOL®.
After closing the 3D environment, you will find the parts list of the installation on the Plans and parts list page. On the Presentation page you will find the button Show mounting system PDF, which opens a PDF file containing the Structural analysis report generated by the mounting system manufacturer in a PDF application.
