Solar Power in Fredericton: Panels, Net Metering and Payback
Home solar works in Fredericton, but the numbers are patient, not spectacular. A typical 8 to 10 kW system costs roughly $27,000 to $34,000 before incentives and produces about 1,100 to 1,150 kWh per kW installed each year, with most of that arriving April through October. NB Power net metering credits your exports at the retail rate (about 15.39 cents per kWh as of April 2026), but any leftover credit balance resets to zero every March 31. Realistic payback runs roughly 9 to 14 years for a homeowner, longer than the sunniest sales pitches suggest. NB Power has also proposed net metering changes (filed with the regulator on April 30, 2026) that would add a residential demand charge, though anyone approved before the rules change is proposed to be grandfathered for up to 10 years.
The short answer: is solar worth it here?
Let us skip the brochure language. Solar in Fredericton is a real, working technology that will shave a serious chunk off your power bill for 25 years or more. It is also a long-horizon investment that pays back slowly, and the economics here are decent rather than dazzling. Fredericton sits at about 46 degrees north, roughly the same solar latitude as Bangor, Maine or the south of France. We get enough sun. What we do not get is a lot of it in December, exactly when our electric-heated homes want the most power.
As of March 31, 2026, NB Power reported 2,134 net metering participants across the province generating more than 29 megawatts of capacity, so plenty of your neighbours have already done the math and gone ahead. The people who benefit most tend to share three traits: a good south-facing roof, high annual electricity use (think heat pumps, an EV, or electric baseboard heat), and the patience to treat the panels like a slow, tax-free bond rather than a get-rich-quick play.
If your household burns a lot of NB Power electricity, solar is worth pricing out. If you use very little, or you might move within five or six years, the payback probably will not land before you sell. This guide walks through the net metering rules, the 2026 proposed changes, real costs, our winter reality, roof fit, permits, and the local installers who actually do the work. Pair it with our home heating guide and our EV guide, because solar makes the most sense when you are already electrifying the rest of the house.
How NB Power net metering actually works
Net metering is the mechanism that makes rooftop solar make sense in New Brunswick. Here is the plain version. NB Power swaps your regular meter for a bi-directional Advanced Metering Infrastructure (AMI) meter that counts electricity flowing both ways: the power you pull from the grid, and the surplus your panels push back out. When your solar produces more than the house is using (a sunny July afternoon while everyone is at work), the extra spins onto the grid and earns you a credit.
Crucially, those credits are currently worth the full retail rate, not a discounted wholesale rate. That is a genuinely good deal and the single biggest reason solar works here. The residential energy rate was 15.39 cents per kWh effective April 14, 2026, so every kWh you export offsets a kWh you would otherwise buy at that price. Credits carry forward month to month, which is how your fat summer surplus covers your thin winter production.
The catch worth tattooing on your forehead: your credit balance resets to zero every March 31. NB Power does not currently buy back leftover energy. If you oversize your system and bank more credits than you can burn by the end of March, that surplus is simply gone, uncompensated. This is why installers size systems to match your annual use rather than maximize production.
Eligibility is straightforward: you must meet NB Power's ownership requirement for the property, the renewable unit (solar, wind, or hydro) must not exceed 100 kW nameplate capacity, which is far larger than any house needs, and the equipment must be certified for use in New Brunswick. You keep paying the monthly service charge regardless of how much you generate, because you are still connected to the grid and using it as your battery. Rules and rates do shift, so confirm the current terms directly with NB Power before you sign anything.
The 2026 changes you need to know about
This is the part that has the local solar community rattled, so read it carefully before you commit. On April 30, 2026, NB Power filed a set of proposed net metering changes with the New Brunswick Energy and Utilities Board as part of a broader rate modernization plan. As of this writing they are a proposal, not law, and the regulator still has to rule on them. But they signal where things are heading.
The headline change for homeowners is a proposed residential demand charge: a fee tied to your highest hour of grid draw in a billing period, on top of the usual per-kWh energy charge. The reasoning NB Power gives is that solar households still lean hard on the grid during winter evenings when their panels produce nothing, and the utility has to build and maintain capacity for that peak. The proposal also reframes export credits to reflect the value of energy at the time it is delivered, acknowledging that solar peaks in summer when demand is lowest, while New Brunswick's demand peaks on cold winter mornings.
NB Power's own materials do not publish final dollar figures, and third-party analyses of the filing circulating among installers suggest the export credit could drop from the retail rate toward an avoided-cost value of roughly 6 to 7 cents per kWh, with a demand charge somewhere in the low tens of dollars per kW. Treat those numbers as unconfirmed until the board rules, and ask any installer to show you the source for whatever figures they quote.
The reassuring part: NB Power has proposed that existing participants, and anyone approved before the new rules take effect, stay under the current rules for up to 10 years. In plain terms, getting your application approved sooner rather than later locks in today's more generous terms for a decade. That is a real, time-sensitive reason not to dawdle if you are already leaning toward yes. Watch for the board's decision, confirm the current rules with NB Power before you commit, and ask any installer directly how the proposal changes your quoted payback.
System sizes, costs and what you actually pay
The average Fredericton-area home is around 1,750 square feet and uses roughly 11,000 kWh of electricity a year, and offsetting that fully takes about a 10 kW system. If you heat with oil or a wood stove and only use power for lights and appliances, you might need half that. If you run heat pumps plus an EV, you might want more. Sizing to your actual annual consumption is the whole game, because of that March 31 credit reset.
Installed pricing in New Brunswick generally runs $2.70 to $3.40 per watt before any incentives, all-in (panels, inverter, racking, labour, permits, interconnection). Here is a rough shape of it. Treat these as ballpark figures to confirm with a written quote, not gospel, because prices move with equipment costs and your roof's complexity.
| System size | Rough cost (before incentives) | Approx. annual output | Good fit for |
|---|---|---|---|
| 5 kW | $13,500 to $17,000 | ~5,700 kWh | Low-use homes, partial offset |
| 8 kW | $21,000 to $27,000 | ~9,100 kWh | Efficient homes with heat pumps |
| 10 kW | $27,000 to $34,000 | ~11,400 kWh | Full offset, some electrification |
| 12 kW+ | $32,000+ | ~13,700 kWh+ | Heat pumps plus an EV |
Two things people forget. First, a battery is a separate and pricey add-on. For pure bill savings under net metering, most Fredericton homeowners skip batteries and let the grid be their storage, though a battery buys you backup power in an outage (see our storm and outage guide). Second, your roof may need re-shingling first, and doing that after the panels are up is expensive, so time it right. A good quote should spell out the panel and inverter brands, the warranties, the expected annual production, and exactly who files the permits, so you can compare bids on more than a single headline price.
Payback at our latitude, and the winter reality
Now the honest part. A well-sited New Brunswick system produces roughly 1,100 to 1,150 kWh per kW installed per year, so a 10 kW array lands near 11,400 kWh annually. That output is wildly uneven across the seasons. Fredericton gets many times more usable sun in high summer than in the dead of December, when short days and a low sun angle cut production to a trickle. Your panels will gush power from May through September and barely stir from December through February, which is precisely backwards from when an electrically-heated Fredericton home wants it. Net metering's summer-to-winter credit banking is what bridges that gap.
Cold itself is not the enemy. Solar panels are actually more efficient in cold air than in summer heat, so a bright, crisp February day can produce beautifully. Snow is the real winter tax. Panels covered in snow produce nothing, and while a decent roof pitch sheds most of it and dark panels warm and self-clear on sunny days, you will lose some winter production to snow cover. Do not climb an icy roof to clear it. It is not worth the ER visit for a few kWh.
Put it together and a typical owner-purchased system pays back in roughly 9 to 14 years at current rates, then produces essentially free power for another decade or more (panels are typically warrantied 25 years and up). If NB Power electricity rates keep rising, payback shortens; if the proposed demand charge and reduced export credit land, it lengthens. Solar is a hedge against future rate hikes as much as a savings play. Factor it into your bigger picture with our Fredericton cost of living guide, and read up on our first winter before you bank on December sun.
Is your roof any good for it?
Not every Fredericton roof is a candidate, and a good installer will tell you honestly. The big four factors are orientation, pitch, shade, and structure.
Orientation: south-facing is the gold standard here. A south slope catches the most sun through our low-angle winter days, and the closer you are to true south, the fewer panels you need for the same output. East and west roofs still work at a modest penalty and can actually spread production across the morning and evening. A purely north-facing slope is a write-off: little to no direct sun hits it, so it generates almost nothing.
Pitch: most Fredericton pitched roofs are fine. A steeper pitch sheds snow faster, which helps winter output. Flat and low-slope roofs can be done with tilted racking but cost more.
Shade: this is the quiet dealbreaker in our leafy older neighbourhoods. Fredericton is the City of Stately Elms for a reason, and a mature elm or maple over the south roof will gut your production (more on the canopy in our urban forest guide). Chimneys, dormers, and vents cast shadows too. Installers use optimizers or micro-inverters to limit the damage, but nothing beats an unshaded roof, so it is worth having an installer model the shading across a full year rather than eyeballing it in July.
Structure and age: your roof needs to be sound and ideally have most of its life left. If you are within five to eight years of re-shingling, do the roof first. Removing and reinstalling panels later runs into real money. An installer will assess whether the deck and framing can carry the added load, and the provincial inspection will not sign off on a substandard job anyway.
Permits, interconnection and inspection
Grid-tied solar in New Brunswick is a regulated job, not a weekend DIY project, and the paperwork is genuinely non-negotiable because you are wiring into NB Power's grid. Here is the sequence, most of which a reputable installer handles on your behalf.
First, an electrical wiring permit is required. Applications go through NB Power (online, or by phone at 1-800-615-0522, weekdays 8:00 a.m. to 4:30 p.m.) and online applications are typically processed within about two business days once approved. Next comes the net metering interconnection application to NB Power, which reviews your system design. Then the physical install happens, followed by a mandatory final inspection by Technical Inspection Services, part of the New Brunswick Department of Public Safety (1-888-659-3222, weekdays 8:15 a.m. to 4:30 p.m., or [email protected]), for which you need your wiring permit number. You cannot legally switch the system on until you have written approval from NB Power and they have installed the bi-directional meter. Turning it on early is both illegal and dangerous to line crews.
For installers, Fredericton has real local options rather than only out-of-town outfits, including names like Ryan's Solar, MJM Solar Solutions, and Epic Energy Solutions, alongside regional companies such as Xolar, Sunly, and Solar X that serve the city. We are not endorsing any one of them. Get at least three written quotes, confirm they are licensed and insured in New Brunswick, ask how many local net metering jobs they have completed, and make sure the quote spells out equipment brands, warranties, and who files the permits. For how permits and trades work more broadly in the city, see our renovations and permits guide.
Rebates, financing, and the bottom line
Incentives here have been a moving target, so verify current status before you build a budget around any of them. The main residential solar rebate ran through NB Power and Save Energy NB under the Total Home Energy Savings Program, offering roughly $200 per kW up to a $3,000 cap (about $1,600 to $2,000 on a typical 8 to 10 kW system) and requiring a home energy evaluation first. That rebate's registration window was set to close May 27, 2026, with installations completed by January 31, 2027, as NB Power shifted funding toward insulation, heat pumps, and air sealing. In other words, if you are reading this after that date, the residential solar rebate has likely wound down, so confirm what, if anything, has replaced it by calling Save Energy NB (1-800-663-6272) before assuming a rebate exists.
The federal Clean Technology Investment Tax Credit (30 percent) remains available through 2033, but only for businesses and farms, not homeowners. On financing, ask installers about payment plans and check whether any provincial low-interest energy loan is currently offered, since these programs open and close. Do not sign a financing deal whose interest quietly erases your energy savings.
| Program | Who | Status to confirm |
|---|---|---|
| NB Power net metering | Homeowners | Active; retail-rate credits, March 31 reset |
| Total Home Energy Savings solar rebate | Homeowners | Registration closed May 27, 2026; verify |
| Clean Tech ITC (30%) | Businesses/farms | Federal, through 2033 |
The bottom line for Fredericton: if you own your home, have a sunny south roof, use plenty of electricity, and plan to stay a decade or more, solar is a sensible, honest investment that hedges against rising power rates. If any of those four are missing, run the numbers hard before you commit, and get your application in sooner rather than later to lock in today's net metering rules for up to 10 years.
Key takeaways
- A typical full-offset home system is about 8 to 10 kW and costs roughly $27,000 to $34,000 before incentives.
- NB Power net metering currently credits your solar exports at the full retail rate (about 15.39 cents per kWh as of April 2026).
- Any banked credit balance resets to zero every March 31, so systems are sized to your annual use, not maximum output.
- Realistic payback in Fredericton is roughly 9 to 14 years, with panels typically warrantied 25 years or more.
- NB Power's proposed 2026 changes (filed April 30) would add a residential demand charge and reduce export credits, but anyone approved beforehand is proposed to be grandfathered for up to 10 years.
- Output is about 1,100 to 1,150 kWh per kW per year, gushing in summer and trickling in December when snow and short days cut production.
- A south-facing, unshaded, structurally sound roof is the key to good economics; north roofs are a write-off.
- Grid-tied solar requires an electrical wiring permit, an NB Power interconnection approval, and a Technical Inspection Services inspection before you can switch it on.
Common questions
Is solar actually worth it in New Brunswick given our winters?
Yes, for the right household, though the payback is patient. Panels are cold-efficient, and summer surplus banks credits that cover thin winter production through NB Power net metering. Expect roughly 9 to 14 years to break even at current rates, then largely free power for another decade or more. It works best if you own your home, have a sunny south roof, and use a lot of electricity for heating or an EV.
How does NB Power net metering pay me back for solar?
NB Power installs a bi-directional meter and currently credits every surplus kWh you export at the full retail rate, offsetting power you buy later. Credits carry over month to month, but the balance resets to zero each March 31 and NB Power does not buy back leftovers. That reset is why installers size your system to match your annual consumption rather than overbuild it.
What are the 2026 net metering changes and should I wait?
NB Power filed proposed changes with the Energy and Utilities Board on April 30, 2026, including a residential demand charge based on your peak hourly grid draw and a lower value for exported energy. It is still a proposal awaiting a ruling. Importantly, anyone approved before the new rules take effect is proposed to stay on current terms for up to 10 years, so getting approved sooner can lock in today's more generous rules. Do not wait; confirm the current status with NB Power.
How big a solar system does a Fredericton home need?
The average local home uses around 11,000 kWh a year, which takes roughly a 10 kW system to fully offset. If you heat with oil or wood and only use power for lights and appliances, 5 kW may do. If you add heat pumps and an EV, you may want 12 kW or more. A good installer sizes it to your actual annual usage.
What permits do I need to install solar in Fredericton?
You need an electrical wiring permit through NB Power, a net metering interconnection approval from NB Power, and a final inspection by Technical Inspection Services (New Brunswick Department of Public Safety). You cannot legally energize the system until NB Power gives written approval and installs the bi-directional meter. A reputable installer handles most of this paperwork for you.
Are there still rebates for home solar in New Brunswick?
The main residential rebate, roughly $200 per kW up to $3,000 through the Total Home Energy Savings Program, had a registration deadline of May 27, 2026, after which NB Power redirected funding toward insulation and heat pumps. Verify current availability with Save Energy NB (1-800-663-6272) before budgeting for it. The federal 30 percent Clean Technology Investment Tax Credit remains but applies only to businesses and farms, not homeowners.
