Decision table

Show qualitative, normalized yield zones for roof direction and tilt before detailed PV modelling or string calculations.

Scroll sideways to keep row labels aligned with hidden columns.

Basis: NRCan PV potential maps and Open Canada photovoltaic potential datasets. The heatmap uses qualitative normalized zones only; linked tables own city and monthly values.

Notes
  • Treat 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.
