Raleigh is Duke Energy Progress territory, which matters for solar because Duke Progress offers retail-rate net metering. Excess power your panels generate gets credited to your bill at the same rate you pay for power you draw from the grid. For homeowners adding battery storage at the same time, the PowerPair program from Duke Energy adds up to $9,000 upfront when you install both together.
The Research Triangle’s newer construction generally has roof orientations that work well for solar. Older neighborhoods like Oakwood and Boylan Heights have more mature tree cover, which is worth factoring into a shading analysis before sizing a system.
What installation involves
A residential solar installation covers panels, racking, an inverter or microinverter setup, and the electrical connection from the array to your main panel. Wake County requires a building permit and a separate electrical permit. Your installer handles both. Duke Energy Progress also requires an interconnection application before the system can export to the grid. This adds a few weeks to the timeline but is handled by your installer as standard.
Costs in Raleigh
The main cost variables are system size (measured in kilowatts), roof complexity, and inverter type. A 7kW system suits a typical Raleigh home with average electricity usage. Shading, roof pitch, and whether you want microinverters or a string inverter all affect the final number. Your installer should provide a detailed quote based on your actual roof and utility data.
Duke Energy PowerPair
The PowerPair program is the main financial incentive currently available to Raleigh homeowners installing solar. It requires you to install solar and battery storage together for the first time at your property.
The incentive structure:
- Solar: $0.36 per watt-AC, up to 10 kW ($3,600 maximum)
- Battery: $400 per kWh, up to 13.5 kWh ($5,400 maximum)
- Combined maximum: $9,000
You must use a Duke Energy-approved Trade Ally installer. The program is first-come, first-served and capacity is limited. Apply before your system is installed if you want to confirm your reservation first. You have 90 days after your system goes live to apply if you install first.
If you also enroll in Duke Energy’s Power Manager Battery Control program, you receive the same one-time incentives plus a monthly bill credit based on your battery’s capacity.
Duke Energy Progress net metering
Net metering in NC changed in October 2023. Customers who installed before that date stay on the legacy retail-rate structure until 2027. New customers choose between the Net Metering Bridge (exports credited at the avoided cost rate, well below retail) or Residential Solar Choice (a time-of-use plan with a low net excess generation rate).
Under both current options, power your panels produce and your home uses directly saves at the full retail rate. The reduced rate applies only to power you export to the grid. Right-sizing the system to match your actual consumption matters more now than it did before 2023.
For the full breakdown of how the current billing plans work, see the NC net metering guide.
Wake County permit process
Solar installations in Raleigh require a building permit and an electrical permit, both pulled by your installer before work begins through the City of Raleigh Development Services portal — most rooftop residential systems qualify for same-day online permitting. After installation, an inspection is required before the system can be energized. Duke Energy Progress then completes the interconnection from their end, which involves a meter change or addition.
The full timeline from signed contract to a live, grid-connected system runs eight to fourteen weeks in Wake County. The physical installation is usually one to three days. The rest is permitting and utility coordination.
