Nova Scotia Power Net Metering Guide: SolarHomes Rebates and Rules

Key Takeaways

• Nova Scotia Power Enhanced Net Metering caps residential installations at 27 kW nameplate capacity.
• The provincial SolarHomes rebate delivers $0.30 per Watt DC up to a maximum incentive of $3,000.
• Unused generation credits are paid out annually in cash every March at the standard retail rate.
• Advanced hybrid inverters like the Sol-Ark 15K deliver 15 kW AC total output and 12 kW battery power during coastal storm blackouts.
• All installations require electrical permitting and CSA C22.1 Rule 64-218 rapid shutdown compliance.

Nova Scotia Enhanced Net Metering: 1:1 Banking and March Cash-Out

Nova Scotia has established one of Canada's most favorable regulatory frameworks for customer-owned distributed generation. Administered by Nova Scotia Power under the Renewable Electricity Regulations and oversight from the Nova Scotia Utility and Review Board (NSUARB), Enhanced Net Metering encourages residential solar adoption.

Under program guidelines, Nova Scotia Power Enhanced Net Metering caps residential systems at 27 kW nameplate capacity (commercial three-phase systems can extend up to 100 kW). Customer arrays must be sized to meet annual domestic consumption needs.

The billing mechanism operates on a true 1:1 kWh basis:

• Monthly Energy Balancing: During each billing cycle, kWh generated by the solar array directly offset kWh consumed from the grid.
• Credit Carryforward: In sunny summer months when generation exceeds household load, excess kilowatt-hours accumulate as credits on your power bill.
• Annual March Cash Payout: Unlike utilities that expire unused balances without reimbursement, Nova Scotia Power pays out accumulated net metering credits annually in March at retail energy rate (~17¢/kWh). This guarantees homeowners complete monetization of every surplus kilowatt-hour generated.

Clean Foundation SolarHomes Provincial Rebate

To lower upfront capital expenditures, Nova Scotia homeowners can access provincial grant funding delivered by the Clean Foundation:

• Incentive Rate: Clean Foundation SolarHomes program provides $0.30 per Watt DC rebate for approved residential systems.
• Maximum Grant: Maximum SolarHomes provincial rebate is capped at $3,000 per residential installation.
• Program Qualification: Systems must be pre-approved prior to installation and installed by an Efficiency Preferred Partner (EPP) using equipment certified to CSA standards.

While federal Greener Homes Grant and Loan programs are closed to new applicants, combining the provincial $3,000 SolarHomes rebate with 1:1 annual cash-out makes Nova Scotia one of Canada's most attractive solar investment markets.

Storm Resilience and Hybrid Storage: Sol-Ark 15K Architecture

Atlantic Canada experiences severe coastal weather, including tropical storm remnants, nor'easters, and freezing rain that trigger widespread electrical distribution failures. To ensure continuous power, maritime homeowners pair solar with advanced hybrid inverters.

The Sol-Ark 15K-2P represents the leading whole-home backup platform for severe coastal environments:

• Whole-Home Power Delivery: 15K whole home advanced back up power 15 kW AC 12 kW AC from batteries 200A grid pass-through.
• Solar Harvesting: Features multiple solar options 6x DC solar ports 3x full sized MPPT.
• High-Rate Charging: Equipped with battery choice 275A battery charger 2x – 48V battery ports.
• Electric Vehicle and Generator Support: Engineered to power and charge your electric vehicles or generators and help reduce your monthly electricity bills.
• Time-of-Use Intelligence: Through the inverter you can intelligently manage energy storage grid usage day-of-week and seasonality based on TOU rates.
• Off-Grid Independence: Designed to continue generating power independently from the grid during prolonged power outages or blackouts.
• Smart Generator Integration: Includes generator ready dedicated gen port autostart capable single circuit smart load functionality.
• Long-Term Battery Strategy: Because batteries wear out faster than inverters and battery technology is still evolving, the open 48V architecture ensures flexible chemistry upgrades.
• Future Replacement Flexibility: The platform succeeds by enabling modern battery features today with easy 48V replacement down the road.
• Complete System Integration: The 15K-2P hybrid solar inverter is a complete whole home backup.

Permitting, Inspection, and Rapid Shutdown Safety

Connecting to the Nova Scotia Power grid requires formal engineering interconnection approval and electrical inspection by Nova Scotia Power wiring inspectors.

All rooftop installations must comply with Canadian Electrical Code Section 64, including Rule 64-218 rapid shutdown compliance. Installers must incorporate CSA-certified rapid shutdown devices to ensure emergency personnel can de-energize rooftop arrays to safe limits within 30 seconds.
