Steps leading to PV layout and results
A. Start a project by following these steps
B. Create a rooftop 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. In the tables below you find the description of each line item. The asterisks (*) in the screenshots indicate that an input is required.
| ID | Description | ID | Description |
|---|---|---|---|
| 1. | Drop-down list to choose region/s for the PV layout | 8. | Target System Size: PV layout aims to reach this system size |
| 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%) |
| 3. | Select between uniform or non-uniform alignment of tables | 10. | East-West Spacing: spacing of tables in the East-West direction |
| 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 | 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) |
| 5. | Azimuth[°]: the direction (in degrees) the tables face, i.e. North: 0°, East: 90°, South: 180°, West: 270° | 12. | Inverter: drop-down list to choose inverter |
| 6. | Skew[°]: : the angle of the layout. Azimuth stays the same | 13. | Target DC/AC Ratio: used to estimate inverter quantity for energy simulation |
| 7. | Start Point: point from which PV layout is created |

ID | Description |
14. | Additional layout configuration: toggle to turn on option for additional North-South, and East-West gap inputs |
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 |
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 |
17. | Apply: creates PV layout |
18. | Reset: erases inputs from PV layout menu |
