Provincial Solar Incentive Schemes Across Canada

Federal Context

Federal involvement in residential solar in Canada has centred on financing and rebate arrangements administered through Natural Resources Canada (NRCan). The Canada Greener Homes Grant — available from 2021 until its closure in early 2024 — offered rebates of up to $5,000 for solar photovoltaic installations, alongside funding for other energy-efficiency upgrades. A complementary interest-free loan of up to $40,000 was available through the Canada Greener Homes Loan, which also closed to new applications in 2024.

Homeowners who completed eligible upgrades under these arrangements before the closure dates and have outstanding loan balances remain subject to repayment terms as published by NRCan. No equivalent federal rebate arrangement was active at the time of publication of this article. The Canada Revenue Agency's Home Renovation Tax Credit for multigenerational modifications is a separate measure not specific to solar.

British Columbia

In British Columbia, the primary mechanism for residential solar owners to recoup value from surplus generation is the net-metering arrangement administered by BC Hydro under the British Columbia Utilities Commission (BCUC) framework. Customers with generating capacity up to 100 kW can apply to net-meter; residential installations are almost universally well under this ceiling.

Under BC Hydro's net-metering terms, surplus electricity sent to the grid is credited at the same rate the homeowner pays for consumption, applied against future bills. Accumulated credits are reconciled annually; any remaining credit is paid out at a lower prescribed rate rather than the full retail rate. FortisBC, which serves parts of the BC Interior, operates its own net-metering arrangement under separate BCUC tariff approval.

The BC government's CleanBC Home Renovation Rebate has historically included heat pumps and insulation but does not, as of this writing, offer specific rebates for solar panel hardware. CleanBC arrangements are subject to periodic updates; the BC Hydro net-metering page and the CleanBC Rebate Centre are the authoritative sources for current status.

Alberta

Alberta has a deregulated electricity market, which creates a different context for solar net-metering compared to provinces with vertically integrated utilities. Micro-generation rules in Alberta are set provincially under the Micro-Generation Regulation (Alberta Regulation 27/2008 as amended). Distribution utilities must connect eligible systems and issue credits for surplus generation.

The credit rate for surplus electricity in Alberta is tied to the regulated rate option (RRO) energy component — a floating spot-market-derived rate — rather than a fixed retail rate. During periods of high wholesale electricity prices (which occurred in Alberta in multiple years through the early 2020s), net-metering credits were correspondingly higher. During low-price periods, credits were reduced.

The City of Calgary operated a Solar Rebate Arrangement for residential customers from 2016 until it exhausted its allocated funding in 2018. No comparable municipal rebate was active in Calgary at the time this article was written. ENMAX and EPCOR provide distribution in Calgary and Edmonton respectively; contact them directly for current interconnection and credit terms.

The Technology Innovation and Emissions Reduction (TIER) regulation applies to large industrial emitters, not residential installations. It is not directly relevant to homeowners installing rooftop solar.

Ontario

Ontario has the longest history of residential solar policy in Canada, primarily through the Feed-In Tariff (FIT) and microFIT arrangements administered by the Independent Electricity System Operator (IESO). The microFIT arrangement — which offered fixed above-market rates for electricity from installations up to 10 kW — was closed to new applicants in December 2017. Existing microFIT contracts with 20-year terms remain active for those who enrolled before the closure.

Since 2017, Ontario residential solar owners connect under the IESO's Net Metering framework, not a feed-in arrangement. Net-metered customers receive a credit on their electricity bill for surplus generation at the time-of-use (TOU) or tiered rate they are billed. Credits are applied against the supply portion of the bill; unused credits accumulate and are cleared annually without cash payment — they do not carry forward as monetary value beyond a rolling 12-month window.

Ontario's residential electricity rates include a Global Adjustment component that varies monthly. Under net-metering, exports only offset the spot-market electricity portion of the bill, not the Global Adjustment. This reduces the effective value of surplus exports compared to a full retail credit model and is a factor in system sizing decisions for Ontario homeowners.

Ontario Green Button and Smart Meters

Ontario mandated smart meters across the province; all residential customers have interval metering. This enables time-of-use billing and means that net-metering calculations can be assessed on an hourly basis rather than monthly averages. Installers and homeowners can use the Green Button data standard to export consumption and generation data for analysis.

Quebec

Hydro-Québec offers a net-metering arrangement for residential customers generating electricity from renewable sources, including solar. The arrangement allows surplus generation to accumulate as credits at the same rate the customer pays — the Hydro-Québec residential rate, which is among the lowest in North America due to the province's predominant hydro-electric generation fleet.

The low electricity rate in Quebec affects the economics of solar investment. With residential electricity prices substantially below the Canadian average, the financial case for rooftop solar is weaker than in provinces with higher electricity costs. Quebec homeowners considering solar installations typically do so for reasons that include grid independence, environmental preferences, or anticipation of future rate increases, rather than immediate financial payback.

Saskatchewan

SaskPower administers the Net Metering arrangement in Saskatchewan for residential customers. Systems up to 100 kW in capacity are eligible. Credits for surplus generation are applied to the customer's account at the retail rate. SaskPower publishes interconnection requirements and the net-metering application process on its website.

Saskatchewan's high solar irradiance — among the highest annual averages of any Canadian province — is frequently cited as a technical advantage for solar installations. Despite this natural resource, provincial electricity prices historically trended below the Canadian average, moderating the financial return on solar investment.

Manitoba

Manitoba Hydro offers a Net Metering Arrangement for customers with systems generating electricity from eligible renewable sources. Surplus credits are applied at the residential rate. Similar to Hydro-Québec, Manitoba Hydro's very low electricity rates — derived from the province's extensive hydroelectric capacity — reduce the financial payback of solar installations compared to provinces with higher rates.

Atlantic Canada

Nova Scotia

Nova Scotia Power (NSP) operates the Net Metering arrangement in Nova Scotia for installations up to 100 kW. The province also administers the SolarHomes arrangement through Efficiency Nova Scotia, which has offered rebates on residential solar installations at various points. Efficiency Nova Scotia is the appropriate authority to check for current rebate availability.

New Brunswick

NB Power offers net-metering to qualifying customers. The province's electricity rates are higher than the national average, which somewhat improves the economics of solar self-consumption relative to western provinces.

Prince Edward Island

Maritime Electric administers net-metering on Prince Edward Island. PEI's electricity rates are among the higher ones in Canada, strengthening the case for solar self-consumption. The province's Renewable Energy Act allows customers to connect generation systems subject to utility approval.

Newfoundland and Labrador

Newfoundland Power and NL Hydro serve different parts of the province. Net-metering availability on the island portion of the province has historically been limited; NL Hydro's Labrador Interconnected System and island grid interconnection rules should be confirmed directly with the utility for current status.

Grid-Tie System Requirements

All grid-connected solar installations in Canada must meet the interconnection standards of the provincial distribution utility and comply with relevant Canadian Standards Association (CSA) standards. Key requirements common to most provinces include:

• Anti-islanding protection — the inverter must automatically disconnect from the grid during a grid outage to prevent energising lines being worked on by utility crews.
• CSA C22.2 No. 107.1 — the standard for grid-connected inverters used in Canada.
• Revenue-grade metering — utilities typically require a bi-directional meter to record both import and export. Smart meters already installed in most Ontario and British Columbia homes serve this function.
• Electrical permit — a permit from the provincial electrical inspection authority is required in all provinces.
• Utility interconnection agreement — a written agreement with the distribution utility is required before energising the system.
