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.

Common questions

Solar Installers in Rockville: quick answers

How are the solar installers in Rockville ranked?

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.

How do I pick the best solar installer in Rockville?

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.

How do I verify a solar installer's license in Maryland?

Licensing in Maryland runs through the Maryland Home Improvement Commission (MHIC) under the Department of Labor. Before hiring anyone in Rockville, look the contractor up in the Maryland Department of Labor's public license search and ask for their MHIC number; plumbers, electricians, and HVAC techs are licensed by their own state boards. Also confirm current liability insurance, and get the license number in writing on the estimate.

This page lists TerraStream Energy, ARHT Home Solutions and Sunburst Solar, LLC, in ranked order. All of them publish a phone number, so you can call directly.

What to look for when hiring a solar installer in Rockville

  • Ask for the MHIC license, plus a master electrician for the hookup. In Maryland, solar installers need it from the Maryland Home Improvement Commission (MHIC). Verify it at the official Maryland license lookup before signing. Installing residential solar panels requires an MHIC license and connecting them to your electrical system requires a licensed master electrician, so verify both.
  • Written estimates. Any solar installer who won't put the scope in writing is a red flag.
  • Review quality, not just volume. Read the 3-star reviews, they're usually the most honest.
  • Local references. A solar installer who's done work in King Farm or Twinbrook will understand local housing stock better than a regional chain.
