Step by Step Guide


Steps leading to PV layout and results


A. Start a project by following these steps

B. Create a fixed tilt table following these steps

C. Open the PV layout menu by clicking on this icon

D. Fill in the required fields. Use the next section 'interface and typical inputs' as guidance

E. Click Apply, your PV layout will be automatically created

F. To review the PV layout results, click on the orange Results button. A new window will open

G. In the PV layout results window you can review your results. You can also 

  • delete results
  • render result in region 
  • clone input in run screen
  • show all result inputs



Interface and typical inputs


The screenshots of the PV layout interface contain numbers for each line item which relate to the numbers in the tables for each line item below. The asterisks (*) in the screenshots indicate that an input is required. In the tables below you find the description of each line item, and if applicable, we give an example of a typical value ('typically') for a fixed tilt ground PV layout.


IDDescriptionIDDescription
1.Drop-down list to choose region/s for the PV layout8.Target System Size: PV layout aims to reach this system size 
Typically: blank
2.Drop-down list to choose table/s for the PV layout 9.North-South Spacing: spacing of tables in the North-South direction; choose between Gap (back edge to front edge), Pitch (center to center), or GCR (Ground Coverage Ratio, 1-100%)
Typically: GCR 50-60
3.Select between uniform or non-uniform alignment of tables
Typically: uniform
10.East-West Spacing: spacing of tables in the East-West direction 
Typically: 2-12 inches
4.Select between quick, normal, or detailed depth of layout algorithm. The more detailed the layout, the longer it will take to create the layout, but the opportunity for increased output will be higher
Typically: any value

11.
Fix Inverter Quantity: toggle to decide on a set number of inverters; by turning it on, the target DC/AC ratio option will disappear and will be replaced by 'inverter quantity' (point 13) 
Typically: toggle off
5.Azimuth[°]: the direction (in degrees) the tables face, i.e. North: 0°, East: 90°, South: 180°, West: 270° 
Typically: 180°
12.Inverter: drop-down list to choose inverter 
6.Skew[°]: the angle of the layout. Azimuth stays the same
Typically: 0°
13.Target DC/AC Ratio: used to estimate inverter quantity for energy simulation
Typically: 1.3
7.Start Point: point from which PV layout is created
Typically: any value

14.
Additional layout configuration: toggle to turn on option for additional North-South, and East-West gap inputs
Typically: toggle on
15.
Additional North-South Gap: allows for placement of additional space in the North-South direction for i.e. roads at a specified interval, by rows or distance
Typically: Rows, every 40-50 rows a gap of 600 inches
16.
Additional East-West Gap: allows for placement of additional space in the East-West direction for i.e. roads at a specified interval, by columns or distance 
Typically: Column, every 10-15 columns a gap of 600 inches 
17.
Apply: creates PV layout 
18.
Reset: erases inputs from PV layout menu
19.
Abort: stops the PV layout creation 
20.
Undo Layout: erases PV layout from map

Manually editing the PV layout


1. Move a table 

  • Choose the Select tool
  • Click on the table(s) you want to move. When selected, they are highlighted in yellow 
  • Choose the Move tool
  • Choose the base point, and the move point. Both are indicated via a yellow dot, connected by a black line. When both points were chosen, the table will automatically be moved


2. Delete a table 

  • Choose the Select tool
  • Click on the table(s) you want to move. When selected, they are highlighted in yellow
  • Press delete on your keyboard
  • A pop up window will appear on the top right side of your screen. Press Save Changes or Reset


3. Copy a table

  • Choose the Select tool
  • Click on the table(s) you want to move. When selected, they are highlighted in yellow 
  • Choose the Clone table tool


4. Edit polygon/keepout vertices

  • Click on Draw ToolKit
  • Select Edit polygon/keepput vertices
  • Click into the polygon
  • Select an edge, drag and drop it
