The Solar X solar calculator estimates the installed cost, recommended system size, first-year production, monthly savings, and payback period for a solar panel installation at your Canadian address. Enter your address and average monthly hydro bill, and the calculator returns a property-specific estimate using NRCan PVGIS irradiance data, your province's current residential electricity rate, and typical Canadian residential solar installation pricing of $2.42–$3.50 per watt.
Estimates assume a 25-year system life, ~0.5% annual panel degradation, and current 2026 net-metering or load-displacement rules in your province. Ontario homeowners can also pair results with Home Renovation Savings Program rebates (up to $5,000 solar + $5,000 battery) and the federal 30% Clean Technology Investment Tax Credit for commercial systems. Actual cost and savings depend on your roof, equipment selection, and installer; Solar X provides a no-charge engineered quote based on your assessment.
