Summary
This article explains how to design a fixed tilt system in OpenSolar—whether for a ground-mounted array or a flat-roof installation. Using the Projects > Design tab, you can layout panels with precision, apply a specific tilt angle, and customize key design parameters such as azimuth, spacing, and orientation. This method allows for quick creation of fixed tilt systems using SolarTouch and advanced layout controls in the sidebar.
Where to Find This
You can access this functionality within:
Project > Design tab in the OpenSolar app.
How to Design a Fixed Tilt System
Follow these steps to lay out a fixed tilt array:
Click the + Panel to begin.
Click, hold, and drag your mouse across the map to:
Place the first row of panels
Set the azimuth (orientation angle)
Release the mouse when the row is the desired length and orientation.
Once the first row is placed, click and drag down from the first panel to make an L shape.
Using the panel menu, use the Fill Rectangle button to fill in the entire space.
Customize the Layout of Your Panels:
Use the left-hand sidebar to configure key settings for your panel group:
| Setting | Function |
|---|---|
| Gap X/Y | Set spacing between modules (columns/rows) in inches or meters |
| Offset Rows | Enable to stagger rows (e.g., brick-style layout) |
| Slope | Adjust the base surface angle (e.g., sloped roof) |
| Azimuth | Set the direction the panels face (e.g., 180° = south) |
| Racks (Tilt) | Enter a numeric value here to set the fixed tilt angle (e.g., 20°) |
Tip: The “Racks” field is where you define the fixed tilt of your system—whether for ground-mount racks or tilted mounting structures on a flat roof.
Final Notes
Fixed tilt systems are ideal for non-tracking configurations on flat surfaces or open fields.
Make use of the “Advanced Layout” options for further control over elevation, orientation, and module row behavior.
