Solar Panel Calculator: Estimate Your Solar Savings in Canada

Free, No-Obligation Estimate
See your estimated installation cost, savings, and payback period in under 60 seconds — no site visit required.

Solar can cut your electricity bill significantly — but the real numbers depend on your roof, your province's electricity rates, and the rebates available where you live. Our free solar panel calculator uses AI-powered satellite roof analysis to generate a personalized estimate for your home, without waiting on a site visit or a sales call.

How Our Solar Panel Calculator Works

Enter your home address and the tool analyzes your roof using satellite imagery — measuring usable roof area, orientation, and shading. We combine that with your local electricity rates, average sun hours for your region, and current provincial and municipal rebates to estimate what a solar installation would actually cost and save at your address. The whole process takes about 60 seconds, and you don't need to know your roof size or energy usage in advance.

What Your Free Estimate Includes

  • Estimated system size and installation cost for your home
  • Projected monthly and annual electricity savings
  • Estimated payback period, based on real, local electricity rates
  • Rebates and incentives you may be eligible for in your province
  • No obligation — you decide if you want to be connected with a local installer

Frequently asked questions

Is the solar calculator really free?

Yes. There's no cost and no obligation to use SolarGuide's solar calculator, and you're never required to book an installation or speak with a salesperson just to see your estimate.

How accurate is the solar savings estimate?

Your estimate is based on satellite imagery of your actual roof, your province's electricity rates, and current rebates — so it's a strong starting point. Your final quote may vary once an installer assesses your roof in person.

Do I need to know my roof size or energy bill?

No. Just enter your address — the calculator estimates your roof's solar potential from satellite data automatically.

Will I be contacted by installers?

Only if you choose to move forward. Your estimate is yours to review first, and you decide whether to be connected with a vetted, local installer.

How long does it take to get my estimate?

Most homeowners get their estimate in under 60 seconds.
