Solar Cost Calculator

Canada-Wide Solar Data & Long-Term Financial Modelling

This free tool is designed to help Canadians evaluate the financial impact of installing solar panels. It uses location-specific solar production data, real utility rates, and up-to-date cost estimates to model your electricity expenses over time—both with and without solar.

The calculator includes projections over 25- and 30-year timeframes, factoring in equipment degradation, utility rate inflation, and regional incentives. It provides a clear cost comparison and allows users to explore system sizing, financing options, and projected savings based on their actual consumption and location.

For users who wish to review the results in more detail or share them with others, a PDF version of the full report is available at the end of the calculation process.

Pinpoint Your Location & Solar Potential

Enter your street address, city, and postal code.
We geocode your location and pull solar irradiance data from a Canada-wide dataset—so you get an accurate estimate of how much solar energy (in kWh per kW) your roof could generate, whether you’re in Vancouver, Winnipeg, or Iqaluit.

Estimate Your Energy Use & Costs

Input your average monthly electricity bill.
Select your local utility provider from a growing list (covering nearly all Canadian utilities).
Adjust your expected annual electricity price increase—defaults to current provincial averages, but can be customized.

Calculate Your System Size

Choose to auto-calculate the ideal system size based on your electricity usage, or manually select a fixed system size (5 kW to 20 kW).
We apply region-specific equipment costs and incentive programs to give you a realistic upfront price estimate.

Compare “With Solar” vs. “Without Solar” Over 30 Years

See a side-by-side cost projection—year by year—for going solar versus staying on-grid.
We factor in solar panel degradation, utility rate inflation, and financing scenarios (if applicable).
Interactive graphs help you visualize your break-even point and lifetime savings.

Present Multiple Financing Options

  • 10-year interest-free utility-backed loan (where available)

  • Self-financed through savings or HELOC

  • No-cost view to explore savings potential without financing assumptions
