About

Solar Worth-It Calculator was built by a Pennsylvania homeowner who was collecting solar quotes and wanted a straight answer: does this price actually pay off now that the federal tax credit is gone?

Most solar calculators online are lead forms for installers. This one isn't. It asks for no contact details, runs entirely in your browser, and shows every formula and source in How we calculate.

Some "Compare quotes" links are affiliate links, which help keep the tool free. Referral payments never change the calculator's math, default values or verdicts — a quote that looks high is labeled high.
