What a system runs in Ontario
| System size | Planning cost range | Year-one saving | 25-year avoided cost |
|---|---|---|---|
| 6 kW | $16,500 to $19,500 | $1,173/yr | $27,566 |
| 8 kW | $22,000 to $26,000 | $1,564/yr | $36,754 |
| 10 kW | $27,500 to $32,500 | $1,955/yr | $45,943 |
Simple payback on the planning midpoint works out to roughly 15 years at any of these sizes. Planning figures on flagged provincial averages, before incentives, not quotes. The full math and every assumption live in the free calculators.
How your surplus power gets credited
Ontario utilities credit exports at retail with a 12-month carryover, and some rebate programs cannot be stacked with net metering, so ask which path fits. The rules that decide what exported power is worth are in our net metering guide, and they are worth reading before an installer sizes your system.
Questions homeowners here ask
How many solar installers serve Ottawa & Eastern Ontario?
53 companies currently serve Ottawa & Eastern Ontario, from national installers to local crews. The busiest home bases are Ottawa and Kingston.
What does home solar cost in Ontario?
Plan around $22,000 to $26,000 installed for a typical 8 kW system, before incentives. Your roof, hardware and electrical panel move the number, which is why quotes are compared in dollars per watt.
How do I choose between installers in Ottawa & Eastern Ontario?
Collect at least three quotes, convert each to dollars per watt, and read the workmanship warranty before the brochure. The company that measures your roof, explains its numbers and answers licensing questions without flinching is the one to shortlist.
Do solar panels make sense in Ontario winters?
Yes. Cold improves panel efficiency and annual estimates already include snow losses. Winter output is lower because days are shorter, and net metering carries summer credits into the dark months.
