Estimate uses regional averages + conservative assumptions. Actual numbers vary by roof, utility, and tax situation. The federal Greener Homes Loan closed to new applicants Oct 2025; the real savings are provincial rebates.

What's behind the number?

  • Rate
    CA$0.13/kWh - Canadian residential blended average. Your actual utility rate is usually higher in winter and lower in summer; we use the annual blended number.
  • Sun hours
    Province-specific peak sun hours per day. ON 3.9 · BC 3.6 · AB 4.7 · QC 3.8. Real installs vary by roof tilt + shading; your installer's site visit produces the actual number.
  • System size
    Back-solved from your bill: annual kWh ÷ (sun-hours × 365). Clamped to 3–12 kW so we don't show absurd residential sizes.
  • 25-year range
    Low end: annual savings × 22 yrs (assumes some rate volatility + panel degradation). High end: × 30 yrs × 1.15 (assumes modest utility rate escalation). The truth is usually mid-range.
