Here's the North Carolina solar landscape: The state ranks #4 nationally for installed solar capacity, driven by good solar resources and utility-scale development. For homeowners, Duke Energy's net metering policies and moderate electricity rates create decent but not spectacular economics. I've tracked Duke's policy changes since 2020.
If you're paying Duke Energy rates in Charlotte or Raleigh (or Dominion rates in the northeast), solar delivers moderate financial returns with solid long-term value. The key is understanding which incentives still exist.
