10.1.2.2 PV array, stand-alone
System > Technical data > PV array
Stand-alone PV arrays require some different data to grid connected ones.
-> How to proceed:
1. Give the array a Name.
2. Select a PV module.
If your desired module is not available, you must first enter it in the PV module database.
Leave the Load file dialog by clicking OK. The parameters are taken over into the current
project.
The complete data record of the selected modules appears in an information window if the
cursor is held over the PV modules button.
3. As required, select the option Create preview of roof layout with Photo Plan.
4. Enter the Installation type: free, with rear ventilation or without rear ventilation.
5. Array output:
- Specify the number of modules: Enter the Number of modules.
- Determine output from roof area: The Minimum distance of the rows of modules
are calculated in the Roof parameters dialog in order to minimize mutual shading
and thus determine the number of modules from the available roof area.
The resulting output of the array is calculated from the number of modules.
6. Orientation
With the help of the Orientation, the irradiation onto the horizontal surface is
converted into irradiation to the inclined PV area.
For stand-alone systems only:
The DC cabling to the charge controller is the cabling from the string distributor of the PV
modules to the charge controller. Standard Cable cross sections are available in the
selection drop-down box; it is possible to enter other cross sections.
The cabling losses in the cables of the individual modules to the string distributor can be
generally taken into account in the "Calculation model and losses" dialog.
If several cables run in parallel to the charge controller, please add together the cable
cross sections of the individual cables.
