Wilmington is Delaware's largest city, a riverfront banking and legal hub on the Christina River. Solar installers design, permit, and install residential and commercial photovoltaic systems, battery storage, and EV charging integrated with solar.
We indexed 3 solar installers serving Wilmington and surrounding neighborhoods, including Trolley Square, Riverfront, Brandywine Village, Little Italy. Each firm is scored on a consistent set of data signals: website health, HTTPS security, mobile-friendliness, online contactability, and alignment with the solar installers niche.

Each business is scored on signals we can verify from public data: a live, secure (HTTPS) website, mobile-friendliness, a published phone number and website, and fit with the solar installers category. We do not collect or display customer reviews, and we do not accept payment for placement. Businesses can claim their listing to correct contact details, but the rank is fixed by the data. Owners can claim a listing for a Verified badge and a direct link; sponsors appear only in labeled blocks outside the numbered list. Neither changes rank.
Each listing is scored on public signals we can check ourselves: whether the website is live and secure (HTTPS), whether it works on a phone, whether a phone number and website are published, and how closely the business matches the solar installers category. We do not collect customer reviews, so no star ratings or review counts appear here, and no business pays for placement.
Use this list to shortlist two or three solar installers, then read their Google reviews yourself, confirm license and insurance, and get written estimates before committing. The score here is a filter, not a verdict.
