Solar incentives can change daily — unmaintained solar calculators actively mislead
Created 2026-06-20
Summary
Claim: Solar incentive blocks (federal/state tax credits, utility rebates) can change daily, so an unmaintained solar calculator misleads visitors within weeks of going stale.

Confidence: Verified.
Why this matters for Candid: The strongest single argument for shipping a directional range rather than a precise number. Even when the math is correct on launch day, the inputs become wrong. See R4 — Commit to a documented input-refresh schedule before shipping any customer-facing calculator; if you won't, don't ship it.
