In this tutorial, we will discuss steps to be taken to reach the required kWp capacity in the selected PV areas for a single-axis tracker PV layout.

The area capacity iteration tool is used to calculate if it is possible to reach the required kWp capacity in the selected PV areas

Iteration parameters

  • Start - it represents the maximum distance that the program will consider for the iteration.

  • Stop - minimum distance considered for the iteration.

  • Iterate by - you can select 1 of 2 options below:

Pitch step - the size of the step for Pitch reduction (iteration step).

Considering the example below, we would have the first iteration with the 10 meters pitch, for the second the software would switch to the stop value of 5 meters, the third iteration would be with 9.5 meters, and the fourth 5.5 meters. This process would be repeated with increments of 0.5 meters each time switching back and forth between the start and stop values.

๐Ÿ›ˆ Pitch /Row spacing - the smaller the step the more iterations will be done and will take more time, however, the accuracy also increases.

  • Required kWp - kWp capacity required to be reached for selected areas.

  • Aligned rows: this is the same option presented in Frame and park settings. Using aligned rows will allow you to have a more orderly layout when there is enough free space.

Area selection

Here you can select the PV areas which you want to iterate. Depending on the placement of your areas, use either a Single area or Multiple areas. The iteration tool will memorize the selection of the areas and you won't need to re-select it.

๐Ÿ›ˆ Select single generation area - select the PV area that should be generated using the single area generation algorithm - no alignment of rows between 2 different areas.

๐Ÿ›ˆ Select multiple generation areas - using this selection will generate PV areas using the multiple area generation algorithms which will keep the same row alignment between the selected areas.

  • Deselect area: removes the selection of a PV area.

  • Selected PV areas - shows how many PV areas have been selected.

  • Total area - displays the sum total area of all selected zones.

  • Reset selection - resets the selection for PV areas.


The last step after having all the parameters set is to proceed with the iteration itself:
