Is solar panel installation worth it in New Brunswick given our cloudy winters and current NB Power net metering rates?

Solar in New Brunswick can absolutely make financial sense, but the math is more nuanced than in sunnier provinces — and the NB Power net metering structure is the critical factor to understand before you commit.

New Brunswick receives roughly 1,850-2,000 peak sun hours annually, which is actually comparable to Germany (a world leader in solar adoption). Yes, winters are shorter and cloudier, but modern panels are more efficient in cooler temperatures — heat actually reduces panel output, so those crisp NB spring and fall days can be surprisingly productive. The real challenge isn't sunlight hours; it's the economics of what happens to the power you generate.

How NB Power's Net Metering Works

NB Power's net metering program credits you for excess electricity exported to the grid, but the rate structure matters enormously. Credits are applied at the retail rate, which sounds great — but credits don't roll over indefinitely in cash. Unused annual credits are essentially forfeited at year-end. This means your system should be sized to match your annual consumption closely, not to maximize generation. Oversizing a system in NB is a common and costly mistake.

The current NB Power residential rate sits around $0.12-$0.13/kWh (check nbpower.com for the current rate as it adjusts periodically). At that rate, payback periods in NB typically run 12-18 years for a well-sized system, compared to 7-10 years in Ontario or BC where rates are higher. That's not a dealbreaker — panels carry 25-30 year warranties — but it's a realistic expectation to set.

Typical System Costs in NB

For a standard 6-8 kW residential system (appropriate for a 2,000 sq ft home using 1,000-1,200 kWh/month):

• Low end: $18,000-$22,000 installed
• Mid-range: $24,000-$28,000 installed
• High end (premium panels, battery storage): $35,000-$50,000+

Battery storage (Tesla Powerwall, Enphase, etc.) adds $10,000-$15,000 and changes the value proposition significantly — it's less about net metering and more about energy independence and backup power during outages, which is a real consideration in rural NB.

The Federal Tax Angle

The federal 30% Clean Technology Investment Tax Credit is available for residential solar installations — this is significant and can meaningfully shorten your payback period. Talk to your accountant about eligibility. NB Power also periodically runs incentive programs, so check their current offerings at nbpower.com before signing anything.

Where Solar Makes the Most Sense in NB

South-facing roofs with minimal shading, pitched between 30-45 degrees, in areas with reliable sun exposure. Homes in the Saint John River valley and southern NB generally perform better than heavily treed rural properties. If you're on a private well with a pump, electric heat, or running an EV — your consumption is higher and the math improves considerably.

One Honest Caution

If you're still heating with oil (very common in NB homes built before 2000), the better first investment is often a cold-climate heat pump to electrify your heating load, then add solar on top of that increased electricity demand. The combination — heat pump plus solar — is where NB homeowners are seeing the most compelling returns.

Get at least 3 quotes from licensed electrical contractors registered with NB Power's net metering program. Any solar installation requires an electrical wiring permit from NB Power (1-800-615-0522) and a TIS inspection (1-888-659-3222) before your system can be connected to the grid — no reputable installer will skip these steps.
