Are solar panels worth it in North Carolina? A decision tree

North Carolina doesn’t give you a clean yes or no on solar the way a high-rate state does. At 15 cents per kWh — below the national average — every kilowatt-hour your panels replace saves you less than it would for a homeowner in California or the Northeast, so the answer genuinely depends on your situation. Rather than one verdict, work through it as a series of questions. Answer them honestly about your own home and the decision tree lands you somewhere real: go now, wait, or resize what you’re planning to buy.

Question one: how big is your electric bill?

This is the branch that matters most, because North Carolina’s electricity is cheap enough that low usage can sink the math outright. If your bill runs $150 or more a month and you own your roof, the size of your usage is large enough for solar’s savings to accumulate meaningfully even at 15¢/kWh — follow this branch down. If your usage sits under roughly 700 kWh a month, the resulting bill is small enough that the eventual savings may not clear the upfront cost within a reasonable horizon — that’s a branch that usually ends in “wait” unless other factors below pull you back in.

North Carolina does have one thing working in its favor regardless of bill size: sun. At 4.8 peak sun hours per day, the state beats most of New England and the Midwest, and roughly matches parts of Texas. An 8 kW system here produces about 11,200 kWh a year after real-world losses — enough to cover the bulk of a typical NC home’s usage. Good sun partly offsets the low rate; it’s the reason North Carolina stays in this conversation at all despite unremarkable electricity prices.

Question two: which Duke Energy rider are you on, and does your usage match your production?

If you’re on Rider NMB — retail-rate netting within each billing period, open to new customers through the end of 2026 — your consumption gets offset at full value in real time. Same with Rider RSC, a time-of-use plan with critical peak pricing, though the timing of your usage matters more there. Either way, the catch is identical: only the leftover net-excess export at the end of a billing period gets paid out, and that’s credited at the avoided-cost NEEC rate — roughly $0.034/kWh, about 75% below retail.

So: do you use a lot of your own power midday — an EV charging on a timer, a heat pump, someone working from home? If yes, follow this branch toward “go solar,” because self-consumption is where the value actually sits. If your home sits empty most of the day and you don’t plan to add a battery, more of your production dumps into that $0.034/kWh bucket than you’d like — that branch leads to “reconsider your system size” rather than an outright no. Oversizing for export doesn’t pay in North Carolina the way it might in a state with better buyback rates.

Question three: are you adding a battery, and is PowerPair still open?

Duke Energy’s PowerPair rebate pays up to roughly $9,000 for solar paired with a battery, when capacity is available in your territory (see our PowerPair guide for current availability and eligibility). If you’re already considering storage — for backup power, or to capture more value from the low NMB/RSC export credit — and PowerPair capacity is open where you live, this branch strengthens the case considerably: the rebate offsets a real chunk of the added cost and a battery also keeps more of your production out of that low avoided-cost bucket. If PowerPair has closed in your area or you have no interest in storage, this branch simply doesn’t change your answer either way — you fall back to whatever branches one and two pointed toward. The other durable incentive in play regardless of this branch is North Carolina’s 80% property-tax exclusion on the value solar adds; see the full picture at North Carolina solar incentives.

Question four: how long are you staying?

Under 3–4 years, the tree ends here regardless of what the earlier branches suggested — you likely won’t recoup the upfront cost in that window. 10-plus years and you’re in the group that captures the most value from the long, patient payback this state requires. Renters, co-op customers with unclear net-metering terms, or homeowners with heavily shaded roofs should stop and verify their specific terms before going further down any branch — those situations sit outside the general math this article covers.

What losing the federal credit costs, regardless of branch

Every branch above assumes the current reality: the federal residential solar tax credit (IRC §25D) expired December 31, 2025, under the One Big Beautiful Bill Act, and a system purchased in 2026 gets $0 federally. At $2.60 per watt installed, an 8 kW system runs roughly $20,800 before incentives (get itemized quotes rather than treating this as exact). Under the old rules, a 30% credit would have returned about $6,240, cutting net cost to roughly $14,560. That amount is gone. Against annual savings of around $1,680, losing the credit adds roughly three to four years to simple payback — a bigger hit here than in high-rate states, because North Carolina’s slower baseline savings take longer to absorb it. If you’re weighing a lease or PPA instead, the company that owns the panels may still claim the commercial §48E credit and pass part of it through as a lower rate — ask how that’s priced, and get it in writing.

Following the tree to a number: 8 kW near Charlotte

For a homeowner who lands on the “go solar” side of the questions above — decent bill, reasonable self-consumption, staying long-term — here’s what that looks like in dollars:

• System cost: 8,000 W × $2.60/W = $20,800 (estimate)
• Federal credit (2026): $0
• Annual production: 8 kW at 4.8 daily sun hours over 365 days, discounted by the same 0.80 real-world derate installers apply everywhere to cover dust, wiring resistance, and the gap between a panel’s lab rating and its actual output under a hot Carolina roof = ~11,200 kWh
• Estimated annual savings at 15¢/kWh: ~$1,680 (assumes most power is self-consumed)
• Simple payback: $20,800 ÷ $1,680 = ~12 years
• 25-year net gain at a flat rate: ~$21,200 (estimate)

A 2% annual electricity rate increase — consistent with the historical trend — shortens payback by a year or more and lifts the 25-year figure further. The 80% property-tax exclusion adds a small, ongoing benefit on top, and landing a PowerPair rebate before capacity runs out drops the upfront number meaningfully if you’re on that branch. Plug your real usage and address into the solar savings calculator rather than relying on this generic path through the tree.

Where the tree ends up

At an estimated $1,680 a year in savings, cumulative 25-year savings total roughly $42,000 against the $20,800 upfront cost — a net gain around $21,200 at flat rates. With payback around 12 years, roughly half the panels’ 25-year working life is spent generating net profit rather than recouping the initial outlay, which is a better ratio than it sounds. North Carolina’s strong sun keeps the tree from dead-ending the way it might in a low-rate, low-sun state — but its 15¢/kWh rate and thin 2026 incentive stack mean most branches lead to a long-horizon “yes,” not a fast one. Detailed pricing sits at solar panel cost in North Carolina.

Before you commit to a branch

The four questions above are only as useful as the numbers you plug into them, so pin those numbers down before anything gets signed. Every installer you talk to should tell you — in writing — which Duke Energy rider your system would land on, what that rider credits for exports, and whether PowerPair capacity is still open in your territory. Compare competing bids line by line rather than by the bottom figure, and check current incentive status on DSIRE — North Carolina’s rules have shifted more than once in the past three years, and a quote built on last year’s tariff is worse than no quote at all. Feeding a year of real bills into the solar savings calculator will show you which branch of the tree you’re standing on before the first site survey.
