How we rank solar installers in Allentown
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.
What to look for when hiring a solar installer in Allentown
- Ask for the Home Improvement Contractor registration (a PA number). In Pennsylvania, solar installers need it from the Pennsylvania Attorney General's Bureau of Consumer Protection. Verify it at the official Pennsylvania license lookup before signing. Solar systems count as home improvement, so a contract over $500 must be in writing with a three business day cancellation right and a deposit capped at one-third on jobs over $5,000.
- 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 Center City or West End will understand local housing stock better than a regional chain.
