US & Canada Solar & EV Tax Incentives Guide 2026

United States: Federal Residential Clean Energy Credit (ITC)

The most impactful solar incentive available to US homeowners is the Federal Investment Tax Credit (ITC), authorized under the Inflation Reduction Act (IRA) of 2022. Through 2032, qualifying residential solar installations receive a 30% direct credit against federal income tax liability — not a deduction, but a dollar-for-dollar reduction of the taxes you owe. On a $24,000 gross system, that represents $7,200 returned directly to you at filing time.

The credit applies to photovoltaic (PV) panels, inverters, battery storage systems installed simultaneously with solar, labor costs, and permitting fees. It is not capped at a maximum dollar amount for residential systems, meaning larger arrays on commercial-grade rooftops in sunbelt states benefit proportionally. Unused credit from year one can be rolled forward to subsequent tax years.

The ITC steps down to 26% in 2033 and 22% in 2034 before expiring for residential installations in 2035 unless renewed by Congress. Homeowners planning a solar investment should treat the current 30% window as a time-sensitive financial opportunity.

United States: State-Level Solar Rebates & Net Metering Laws

Beyond the federal ITC, most US states layer additional incentives. California's SGIP (Self-Generation Incentive Program) offers rebates for battery storage. New York's NY-Sun initiative provides per-watt incentives for installations below 25 kW. Massachusetts maintains one of the country's most generous solar incentive stacks with the SMART program, offering fixed payments per kWh generated for 10 years post-installation.

Net metering policies also vary dramatically. States with full retail-rate net metering — including New Jersey, Maryland, and Colorado — allow homeowners to export surplus solar energy to the grid at the same rate they would pay to import it, dramatically improving 25-year lifetime return calculations. Always verify your current state utility commission's net metering tariff before finalizing system sizing, as policy changes can alter payback projections by 1–3 years.

Canada: Greener Homes Grant & Provincial Solar Programs

Canadian homeowners benefit from the federal Canada Greener Homes initiative, which provides grants of up to CA$5,000 for eligible energy efficiency upgrades including solar PV installations. Combined with the federal 30% Clean Technology Investment Tax Credit (ITC) for qualifying residential solar, Canadian homeowners can offset a substantial portion of gross installation costs at the federal level alone.

Provincial programs add further layers of incentive. Ontario's net metering program under the Independent Electricity System Operator (IESO) allows bi-directional metering. British Columbia Hydro provides net metering credits. Alberta's Residential and Commercial Solar Program has historically offered direct rebates per watt installed. Quebec's Hydro-Québec net metering program covers the full province under a unified billing structure.

SolarPathCalc accounts for all active federal and provincial incentive schedules when computing your Net System Cost, ensuring Canadian homeowners receive an accurate after-credit projection rather than the misleading pre-incentive sticker prices commonly quoted by installers.
