Solar Incentives and Rebates Nova Scotia (2026)

With residential rebates closed, the entire economic case for solar in Nova Scotia now hinges on NS Power's net metering program. The good news is that it is genuinely the strongest residential net metering arrangement in Canada, crediting every kWh exported to the grid at the full retail rate. That is materially better than most provinces, where utilities pay only the wholesale value of exported power (often 4 to 10 cents per kWh, versus NSP's 18-plus cents).

How It Works

• Credit rate: 18.187¢/kWh (NS Power Domestic Service Tariff energy charge as of January 1, 2026)
• Base charge: $19.17 per month customer charge applies regardless of net usage (solar credits cannot offset this)
• Rollover: Surplus credits roll over for up to 12 months
• System size cap: Up to 100 kW per residential or small commercial site
• Multi-site sharing: Credits from one property can offset bills on another property you own in the same NSP distribution area
• Battery compatible: Adding battery storage does not change your net metering eligibility
• No admin fees on residential systems under 27 kW

Why This Matters More Than a Rebate

Over the 25-year warranty life of a typical residential solar system, NS Power net metering delivers cumulative savings of $40,000 to $90,000 for an average home, depending on usage and system size. Compare that to the $3,000 SolarHomes rebate that closed in 2025, and net metering alone is worth roughly 15 to 30 times more over the system's life. The closure of SolarHomes was disappointing in the short term, but the underlying economics of solar in this province remain very strong.

While residential incentives have shrunk, the commercial and non-profit picture in 2026 is actually stronger than it has been in years thanks to the federal Clean Technology Investment Tax Credit and the Solar for Non-Profits pilot.

Federal Clean Technology ITC (Commercial)

The Government of Canada's Clean Technology Investment Tax Credit provides a 30% refundable tax credit on the cost of eligible clean technology equipment, including solar PV systems and battery storage, purchased and put into use by a Canadian business. Key terms:

• Eligibility: Canadian-controlled private corporations, public companies, partnerships, and certain non-profits (cooperatives, mutuals)
• Credit value: 30% of capital cost of eligible equipment, refundable (meaning even non-tax-paying entities can receive cash back)
• Stacking: Combines with accelerated CCA Class 43.1 or 43.2 depreciation (30 to 50% first-year writedown)
• Sunset: Phase-down begins in 2034
• Result: For a $200,000 commercial solar install, you receive $60,000 back as a federal tax credit plus substantial first-year CCA deduction

Solar for Non-Profits Pilot (Efficiency Nova Scotia)

The Solar for Non-Profits pilot remains active for registered non-profits and charities operating in NS for at least 12 months. Terms:

• Rebate value: $0.60/Watt of installed DC capacity
• Maximum: $15,000 or up to 25% of pre-tax system cost, whichever is lower
• System size: Up to 25 kW
• Eligibility: Active registered non-profit or charity for minimum 12 months
• Site visit: Participation in Efficiency NS site visits is required

Commercial NS Power Net Metering

NS Power's Commercial Net Metering tariff has a 1 MW cap and credits surplus generation at the applicable retail rate, rolling over for 12 months. Projects above 1 MW require an Embedded Generation Agreement or a Power Purchase Agreement (PPA), each with different economics. The Renewable Electricity Regulations under the Electricity Act govern these structures.

Community Solar Gardens (Provincial Pilot)

The Province of Nova Scotia is targeting 50 MW of community solar capacity by 2026 through a program enabling private developers, Mi'kmaw bands, non-profits, and the municipal and post-secondary sectors to enter Power Purchase Agreements with NS Power. The program is structured for developers rather than individual homeowners, but participation indirectly benefits ratepayers through cleaner generation. Source: Province of Nova Scotia announcement.

For a typical 2026 NS residential solar project, here is how the active programs combine:

1. System size: 10 kW solar PV, all-in installed cost roughly $28,000 with HST included
2. PACE financing (Halifax Solar City or municipal equivalent): Covers full system cost, $0 upfront, repaid through property tax bill at 4.75% over 10 years
3. Monthly NS Power bill before solar: $220 to $300 for a typical household
4. Monthly NS Power bill after solar: $25 to $50 (just the base charge plus minor net usage)
5. Monthly PACE payment: $293 (fixed for 10 years)
6. Net monthly cash flow year 1: Roughly break-even to modestly positive depending on usage
7. Years 2 through 10: Improving cash flow as NS Power rates rise but PACE payment stays flat
8. Years 11 through 25: Full electricity savings flow to the homeowner (no more PACE payment); typical $200 to $350/month in pure savings

A homeowner who keeps the property the full 25 years comes out roughly $40,000 to $60,000 ahead of staying with grid-only electricity, depending on usage and how aggressively NS Power rates rise. For commercial customers, the federal Clean Tech ITC dramatically improves these numbers further.
