Find a licensed solar contractor in Delaware
Every solar contractor here holds an active state license, re-verified weekly. Tell us about your home. Get matched with licensed pros who won't oversell your roof. Free for homeowners.
Why verification matters
Solar is a magnet for high-pressure sales and undersized systems on bad financing. A licensed installer handles the electrical, permit, and utility interconnection legally - and stands behind the production estimate.

The state board's job ends at the license. Ours starts there.
Solar installers are split across multiple license categories depending on the state — C-46 in California, AES (Alternative Energy) in Virginia, sub-specialties under electrical in others. ContractorRoster collapses those into a single search and delivers every active solar installer with phone, email, and website in one CSV.
Delaware: Delaware licenses electricians, plumbers, and HVACR contractors through the Division of Professional Regulation, and every other contractor working in the state holds a Division of Revenue contractor business license. Both rosters are published as state open data, refreshed daily. Phone and email aren't in the state files, so we fill them from public sources; business-license records carry the full street address. Out-of-state firms licensed in Delaware are excluded from these results by default so you see in-state contractors first.
