Solar Calculator Nova Scotia

NS Power offers net metering to residential customers with solar systems. You receive credits for surplus generation at the retail rate, which credits are applied to future bills. The program includes an annual true-up. Nova Scotia's net metering program has a queue-based capacity limit—verify current enrollment availability with NS Power before purchasing. System size must not exceed your anticipated annual consumption.

Nova Scotia has some of the highest electricity rates in Canada—NS Power's standard residential rate is approximately 18.2¢/kWh, with the all-in effective rate approaching 20–22¢/kWh including distribution charges. Every kWh of solar you self-consume saves you at that high rate. Combined with the federal 30% Clean Technology ITC, Nova Scotia consistently achieves among the fastest solar payback periods in Atlantic Canada.

NS Power's standard residential (Rate 12A) energy charge is approximately 18.187¢/kWh. With the basic monthly charge, distribution charge, and HST, the total effective bill rate is typically 20–22¢/kWh when all charges are included. Nova Scotia has among the highest electricity rates east of Ontario, making solar savings substantial per kWh of production.

Nova Scotia residents can access the federal 30% Clean Technology Investment Tax Credit on eligible solar systems. Nova Scotia's EfficiencyOne organization has historically offered programs supporting residential energy upgrades—check their current offerings for any applicable solar incentives. NS Power's net metering program provides the ongoing savings mechanism. The province's high electricity rates make the financial case strong even without provincial rebates.

A typical 7–8 kW residential solar system in Nova Scotia costs $19,000–$25,000 before incentives. After the federal 30% Clean Technology ITC, net cost is $13,300–$17,500. Halifax and Dartmouth have the largest installer base and most competitive pricing; rural Nova Scotia may have slightly higher quotes. Get 3+ quotes for best results.

With NS Power rates at ~18¢/kWh and the federal 30% ITC reducing upfront costs, Nova Scotia solar typically achieves payback in 8–11 years—among the fastest in Atlantic Canada. A typical 8 kW system generates ~8,000 kWh/year, saving $1,440/year at 18¢/kWh. Over 25 years with 3% annual rate escalation, 25-year savings can exceed $45,000 on a $17,500 net-cost system.

Yes. Halifax averages approximately 1,900 peak sun hours per year—more than you might expect for Atlantic Canada. The southern coastal areas and Annapolis Valley receive the most sun. Modern high-efficiency panels handle Nova Scotia's Atlantic weather well, and salt-air resistant racking is standard for coastal installations. Winter production is lower but summer more than compensates over an annual period.

As of 2026, the primary Nova Scotia solar incentive is the federal 30% Clean Technology ITC. The previous EfficiencyOne Solar Homes rebate program has evolved—check EfficiencyOne.ca for current residential solar incentives. The Canada Greener Homes Grant is closed. Some Efficiency NS programs (heat pumps, insulation) may be stackable with solar investments, improving overall home energy ROI.
