Chart
Solar roof orientation and tilt yield heatmap
Compare how roof azimuth and tilt affect annual solar yield for Canadian PV planning conversations.
Chart boundary
Does not calculate system output, account for shading, approve interconnection, or replace PV design software.

Orientation and tilt yield zones
Use the qualitative heatmap to compare unshaded roof options before moving to city data, PV modelling, string, and interconnection details.

Decision reference
Show qualitative, normalized yield zones for roof direction and tilt before detailed PV modelling or string calculations.
| Method | Best fit | Watch point | Handoff |
|---|---|---|---|
| South roof plane | Annual yield priority | Shading and roof area still govern | PV design model |
| East / west roof plane | Distributed production windows | Lower peak on each face | Inverter sizing review |
| Flat or low slope | Flexible racking decisions | Wind, ballast, snow, access | Structural and PV design |
| Steep roof | Snow shedding and fixed geometry | Access and orientation limits | Installer site survey |
Use notes
- Use this chart as a planning and conversation aid only.
- Confirm current utility requirements, product markings, manufacturer instructions, and local authority requirements before field work.
- Use the linked calculator or table when the task needs project-specific arithmetic.
