Solar Panel Cost in Ontario After Rebate

Sticker prices for solar are easy to find; what you actually pay after the Home Renovation Savings rebate is harder. This calculator works from your system size and a per-watt cost, subtracts the rebate using the real program formula, and estimates a simple payback from your hydro bill. Every assumption is editable.

How the numbers work

Gross cost is your system size multiplied by the installed cost per watt. In Ontario that figure commonly lands somewhere around $2.20–3.00 per watt depending on equipment, roof complexity, and installer — so it's left editable rather than fixed.

The rebate follows the Home Renovation Savings formula: $1,000 per kW of solar (max $5,000), plus $300 per kWh of battery if you add one (max $5,000), with each part capped at 50% of its cost and a combined ceiling of $10,000. Net cost is simply gross minus rebate.

Simple payback divides the net cost by your estimated annual savings, which the tool derives from your monthly bill and how much of it the system offsets. It deliberately ignores rate inflation, financing, panel degradation, and maintenance — so treat it as a rough orientation, not a quote. For a fuller picture of self-consumption versus exporting power, the rebate vs. net metering calculator models 10-year totals both ways.
