Solar.com plainly states its calculator "is based on assumptions and does not represent a binding solar quote"
Created 2026-06-20
Summary
Claim: Solar.com's savings/ROI calculator is plainly labelled non-binding: "based on assumptions and does not represent a binding solar quote." Similar non-binding labelling is universal across solar estimators (EnergySage, Google Project Sunroof).
Source: Solar.com https://www.solar.com/learn/solar-calculator/
Confidence: Verified (the labelling is on-page).
Why this matters for Candid: A worked example of R3 — Label every published estimate as an estimate, and show its vintage prominently in the wild. The discipline is to make the disclaimer as visible as the number it qualifies — not buried in fine print.
