Where this list comes from
Our Delaware roster uses covered records from Delaware DPR (Division of Professional Regulation) + Division of Revenue. A current source check is still needed. Counts describe records in that snapshot, not every business operating in the state.
A license or registration record is a starting point. Credential types and scope differ by jurisdiction; a listing does not establish today's status or authorization for every type of work.
Before hiring, match the business and credential number with the relevant authority, check scope and current status, and confirm local permits. Contacts and Google ratings, when present, are separate enrichment rather than licensing evidence.

Delaware: credentials and scope
Delaware separates the Division of Revenue business license, Department of Labor contractor registration and professional trade credentials. Construction businesses must address the registration requirements before work begins.
A revenue license is not an electrical or other professional license. Check the relevant DELPROS credential separately and confirm local requirements for the project.
Example: For electrical construction, verify the professional electrical license as well as the business and contractor-registration requirements.
Keep the three Delaware checks distinct
- Identify the business’s Division of Revenue license and Department of Labor contractor registration. These answer different administrative questions.
- For electrical and other regulated trades, search the relevant DELPROS professional credential separately. A revenue license is not an electrical license.
- Ask the project jurisdiction about permits and local requirements. Keep the exact business name and credential numbers together so similarly named entities are not combined by mistake.
Example: an electrical contractor sends a revenue license. Ask for the professional electrical credential and the applicable contractor-registration information instead of treating the revenue document as trade authorization.

Common questions about solar contractors in Delaware
How do I research solar contractors in Delaware?
Start with the authority for the trade and project locality. Match the exact business and credential number, check current status and scope, then ask about local permits, insurance and comparable work. A directory listing or rating does not complete those checks.
How many solar contractors does the Delaware roster cover?
Our snapshot contains 38 records in this category. Records are not necessarily unique companies, and source coverage is not a census of every business in the state.
Where does this data come from?
Covered records come from Delaware DPR (Division of Professional Regulation) + Division of Revenue. License and registration types differ; check the credential that applies to your project. Contacts and ratings are separate enrichment where available.
What contact information is included?
Available fields can include phone, email, website and Google ratings. Availability varies by record and selection; an unavailable field is not a zero, closure or negative finding. Review the selected inventory before purchase.
What will my list cost and when will it arrive?
The current purchase flow shows the price for your selected territory and filters before checkout. Larger website orders are typically delivered within one business day. Custom research scope and delivery timing are agreed before purchase.
Does this list establish current license status?
No. The recorded source refresh date is 2026-07-10. This is a snapshot rather than a live-status guarantee. Verify the appropriate official record before hiring.
