How Raleigh homes get paid for solar
Export rules are set at the state and utility level, not by the city. Raleigh is under North Carolina's net billing: Duke Energy's Residential Solar Choice (since Oct 1, 2023) nets use and production each month, then credits surplus at avoided cost, below retail. New customers move to it in 2027. The full rules, incentives and sources are on theNorth Carolina page.
Why the city matters
Two things change from one city to another in the same state: the sun, which sets how many panels you need, and the utility, which sets what exported power is worth. Raleigh gets 1,427 kWh per kW a year on a south-facing roof at a 20° tilt, so covering a year of use for a $150 bill at 14.9¢ takes about 8.4 kW, roughly 22 panels of 400 W. Electricity prices in the calculator are the North Carolina residential average; your utility's rate can be higher or lower, so put your own bill in.
