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.

- ✓Module, inverter, or rack-system distributor outreach by metro
- ✓Installer-network recruitment for residential solar finance programs
- ✓Building a county sales list for monitoring, O&M, or software vendors
