Tilted Panel Row Spacing Calculator
Calculate simple geometric shadow clearance for an entered solar elevation angle.
Open this toolTilted rows can cast shadows into the space behind them. The relevant solar angle needs a site and time basis.
Enter panel geometry, tilt and a suitable elevation angle. Review the ideal clearance before adding terrain and orientation considerations.
Inputs and controls
Panel tilt
Geometry · degrees
Allowed range: 0 to 89
Design solar elevation
Geometry · degrees
Allowed range: 0.01 to 89.99
How to use
- Enter panel slope length, panel tilt and design solar elevation.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why use this tool
The geometric view helps explain why tilt and sun elevation change the spacing requirement.
Before relying on the result
Ideal level ground with sun normal to the row direction. Elevation must come from a site and time calculation; this tool does not derive it from a city. Terrain, azimuth and multiple structures alter shading.
Tool limitations
Ideal level ground with sun normal to the row direction. Elevation must come from a site and time calculation; this tool does not derive it from a city. Terrain, azimuth and multiple structures alter shading.
Questions
Is solar elevation calculated from a city name?
No. Supply it from a suitable site and time calculation. The tool does not derive local sun angles.
What should I check before using Tilted Panel Row Spacing Calculator?
Check Panel slope length, Panel tilt and Design solar elevation. Use the exact units shown beside the controls and replace any example values with your own inputs.
