Enter two numbers off a recent bill and get your recommended system size, your locked-in solar rate in cents per kWh, and what staying on the grid could cost over the next 25 years — Ontario-calibrated, no phone call required.
No phone call required. We'll use your real hydro bill to estimate a custom system size, your locked-in solar rate, and what you'd pay your utility over the next 25 years if you do nothing.
Your recommended system size — based on your actual usage, calibrated to Ontario.
Your solar rate in cents per kWh — locked for 25 years and compared to what you pay hydro today.
Your 25-year utility cost if you stay on the grid. (Most homeowners are surprised by this number.)
Your potential rebate from the Ontario Home Renovation Savings program — eligibility assessed during your proposal.
The Solar X Solar Savings Calculator estimates your recommended Ontario solar system size, your locked-in 25-year solar rate in cents per kWh, and what you might pay your utility over the next 25 years if you stay on the grid. The estimate is built from your average monthly hydro bill, your annual kWh usage, and any future loads you select (EV, heat pump, pool, hot tub).
All numbers are Ontario-calibrated: peak sun hours of 4.2, standard 15% DC→AC conversion losses, a 25-year system life, and a 4% annual utility-rate inflation trend (Ontario historical average).
Estimates only. Ontario homeowners may qualify for Home Renovation Savings Program rebates of up to $10,000 on qualifying solar installations — eligibility is assessed during your proposal. Pair your results with the federal 30% Clean Technology Investment Tax Credit for commercial systems. Actual cost, financing, and savings depend on your roof, equipment selection, and installer; Solar X provides a no-charge engineered quote based on your assessment.
