Solar in Raleigh

The Raleigh-Durham area (Research Triangle) has solid solar potential with good sunshine and an educated homeowner base interested in clean energy. Duke Energy Progress serves most of the region with policies that support residential solar.

💡

From my experience:The Research Triangle is a good solar market partly because so many neighbors already have it. When you've got engineers and tech workers who understand the math, word spreads fast. Installer competition keeps prices honest. The Duke Energy policy situation is worth watching, but the Triangle's educated homeowner base keeps pressure on utilities to maintain reasonable solar programs. If your neighbor has panels, they probably got a fair deal and can share their experience.
