Principles
- Every cost or savings figure is labeled an estimate, with its method documented in how our estimates work.
- We don't make unsupported claims — no "best installer", "lowest price", "guaranteed savings" or "guaranteed tax credit".
- Commercial relationships (referral fees, affiliate links) never determine editorial content, rankings or which installers you're matched with. See the disclosure.
- We don't publish fake reviews, ratings, testimonials or customer counts.
Sourcing
Solar economics draw on public data (NREL, EIA, DSIRE) and clearly-labeled representative assumptions. Installer facts come from company websites and public records; unverified fields are marked as such.
Updates and corrections
Tax-credit status, incentive figures and pricing assumptions are reviewed as programs change. To report an error, contact us; we correct confirmed errors promptly and note material changes.
