North Carolina solar costs $2.70–$3.10/watt. Here is the full honest breakdown: gross price, every available incentive, and realistic payback math at current Duke Energy rates.

$2.70–$3.10/W

Installed cost

Net metering + 80% exemption

Main incentive

8–11 yrs

Typical payback

~$0.12–$0.14/kWh

Utility rate

North Carolina has some of the most competitive solar prices in the Southeast: $2.70 to $3.10/watt, reflecting a mature, competitive installer market across the state. Combined with full retail-rate Duke Energy net metering and the 80% property tax exemption, the net cost and payback picture is solid for most NC homeowners.

System sizes and costs

6 kW: $16,200–$18,600. Produces ~8,000–9,000 kWh/year in NC.
8 kW: $21,600–$24,800. Most common. Produces ~10,500–12,000 kWh/year.
10 kW: $27,000–$31,000. For larger homes or EV charging.

Payback math

An 8 kW NC system producing 11,000 kWh/year at Duke’s $0.13/kWh rate offsets $1,430/year. Net cost: ~$22,000. Payback: approximately 15 years at base rates. However, Duke Energy rates have risen historically, and homeowners who add EV charging increase annual savings significantly. Many NC homeowners see 10 to 12 year payback when accounting for rate escalation and diversified usage.
