Solar Panel Cost in Charlotte, NC (2026 Estimate)

ByIndependent solar research and calculators

Data last updated

Charlotte averages about 4.9 peak sun hours a day (about average for the US, a little sunnier than the North Carolina average of 4.7), and pairs with North Carolina's approximate residential rate near 13ยข/kWh. In the model used here, an 8 kW system produces roughly 11,450 kWh a year and trims about $1,500 off annual electricity costs, paying back its net cost in about 10.2 years (versus 10.6 years for North Carolina as a whole). Local shading, roof, and your utility's export terms move the real figure.

Estimated system cost and payback in Charlotte

Costs assume roughly $2.70/watt installed; the net column applies a 30% federal credit for comparison with quotes that include it. Savings use Charlotte's sun hours and North Carolina's rate.

System size Gross cost Net after 30% credit Yearly production Yearly savings Payback
6 kW $16,200 $11,300 8,580 kWh $1,100 10.2 yrs
8 kW $21,600 $15,100 11,450 kWh $1,500 10.2 yrs
10 kW $27,000 $18,900 14,310 kWh $1,900 10.2 yrs

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

Net metering and utilities around Charlotte

Duke Energy Carolinas and Duke Energy Progress moved to a new net metering structure for customers interconnecting from October 2023 onward, following a settlement approved by the North Carolina Utilities Commission. New solar customers choose between two tariffs. The Residential Solar Choice option pairs net metering with a time-of-use rate, nets production against usage within each pricing period, credits any monthly surplus at an avoided-cost rate, and applies a minimum monthly bill along with non-bypassable charges.

Duke Energy Carolinas serves Charlotte, the Triad and the western mountains, Duke Energy Progress covers Raleigh, Wilmington and the eastern plain, and Dominion Energy North Carolina handles a corner of the northeast around Elizabeth City. Roughly a quarter of the state's customers get power from 26 electric cooperatives or municipal systems such as those in Wilson and Greenville, each with its own board-set solar terms. Duke's residential rates are below the national average, which caps how much each net-metered kilowatt-hour can save, and the time-of-use requirement means shifting laundry and EV charging away from the evening peak matters more than it did under flat-rate net metering. A battery improves the math by holding midday output for the pricier evening hours.

Every figure on this page is computed from two published inputs (average peak sun hours and the state's average residential electricity rate) plus the documented assumptions on the methodology page. It is a transparent model, not a survey of installer quotes. Inputs last reviewed .
