Find out if solar pays on your roof.
Enter your address. We measure your roof from above, design panels on it and price the result against your real electricity bill. You get an honest answer before anyone calls you.

Sample roof
- We don’t sell or install panels. Our job is to tell you whether solar is worth it.
- Your roof, measured from above, face by face, with a sun map of every spot.
- Every number shows its math. Change any assumption and watch the result move.
From address to answer in about a minute
Step 1
Find your roof
Type your address. We pull the aerial view and a 3D model of your roof, and measure each face's direction, pitch and yearly sun.
Step 2
Add your bill
Your monthly amount or kWh, and your electricity company. We know your rate plan's prices, delivery charges and taxes.
Step 3
Design it
We place panels to cover your use. Add or remove them, try a battery, pick a panel. Savings update as you go.
Step 4
Decide
See payback, monthly bills before and after, rebates and financing. Save it, share it, or ask one vetted installer for a quote.
The same house pays back very differently across Canada
One sample home, one $180 monthly bill, sized for the best return, run through our model in five cities. Rates, sun and the rules for power you send back to the grid decide the answer, which is why we ask where you live before we say anything.
How payback works| City | System | Year-1 savings | Pays back in | Our verdict |
|---|---|---|---|---|
| TorontoToronto Hydro | 7.3 kW | $1,471 | 11.9 years | Good fit |
| CalgaryAlberta (regulated rate) | 5.6 kW | $1,005 | 14.8 years | Marginal |
| HalifaxNova Scotia Power | 9.9 kW | $1,988 | 13.6 years | Good fit |
| VancouverBC Hydro | 15.5 kW | $2,028 | 18.8 years | Not recommended |
| MontréalHydro-Québec | 8.6 kW | $970 | 21.9 years | Not recommended |
Model estimates using current default rate plans and average installed prices. Your home will differ.

Questions people ask first
Is SolarMyBill really free? What's the catch?
It's free for homeowners. If you ask for quotes, the installer we introduce you to pays us for the introduction. We never share your details unless you ask us to, and only with one installer.
How accurate is it?
The roof measurements come from high-resolution aerial imagery and 3D roof models. Savings depend on your bill, your rate plan and your province's rules, and we simulate every hour of a typical year. Expect the estimate to land close to a good installer's proposal; an on-site visit confirms the final numbers.
Will someone call me?
Only if you ask for quotes. You can see your roof, design a system, read your savings, download the report and share it without giving us a phone number.
Does solar work in Canadian winters?
Yes, but it makes much less in December than in June. Panels work well in the cold and snow slides off tilted roofs. Where net metering exists, summer credits cover part of the winter bill.
What if solar doesn't make sense for my home?
We'll say so, and tell you why: too much shade, a small or north-facing roof, very cheap electricity, or no credit for power you send back. Sometimes a battery, a rate-plan change or waiting for a new roof is the better move.
