Why this site exists

Solar research online is broken in a specific way. The sites that rank are lead brokers wearing an editorial costume. The "best installers" are the companies paying for placement. The savings calculators still assume a federal tax credit that died at the end of 2025. Nobody publishes their math, their sources, or who pays them.

We are a solar installer, and we also partner with other solar companies. You should read everything here knowing that. The difference is we say it on every page, we publish the grading rubric, and we grade our own installation business with the same rubric we apply to competitors. The grading database is structurally walled off from the revenue side: nothing in the grading tables links to the money tables, and that is by design, not by promise.

The numbers on this site come from EIA utility data, NREL production models we run ourselves, state statutes we link directly, and LBNL cost research. When a number cannot be verified, we mark it unverified instead of publishing it anyway. When the data is a company's own claim, we label it a claim. That standard is documented on the methodology page and the data sources page.

If you find an error, tell us and we will fix it and log the correction. That is the whole editorial policy, and the longer version lives here.
