The Home Solicitation Sales Act (HSSA) is a California law giving a homeowner a 3-day right to cancel an in-home sales contract, including solar, extended to 5 days if the buyer is 65 or older, published directly by the CPUC as part of its California Solar Consumer Protection Guide.
HSSA (Home Solicitation Sales Act) explained
The HSSA sits on top of the federal 3-business-day FTC Cooling-Off Rule baseline as California's specific standard, with the added senior-protection extension to 5 days. The CPUC publishes it directly as part of an official California Solar Consumer Protection Guide, which makes it the confirmed, primary-source standard for the state.
A note on accuracy: some secondary marketing content references a newer "SB 784" update to California's solar cancellation law for 2026. This claim could not be verified against California's primary legislative record and is not treated as confirmed here; the HSSA as published by the CPUC remains the verified standard.
California solar sales in 2026 are also happening under a separate, unrelated change worth knowing alongside the HSSA: NEM 3.0 cut solar export credits by roughly 75% starting in April 2023, and the older NEM 2.0 grandfathering window closed entirely on April 15, 2026, with a state Court of Appeals upholding NEM 3.0 against legal challenge in March 2026. A homeowner's cancellation rights and their net-metering economics are two different, both-real, changes to what they're agreeing to, and conflating the two in a sales conversation confuses rather than informs.
Why it matters when you're buying
Disclose the HSSA cancellation window clearly and separately from the NEM 3.0 economics conversation. "You have days to change your mind" and "your export credits have changed" are two different facts a California homeowner needs, and blending them into one conversation does the homeowner a disservice.
