Wisconsin solar cancellation rights

Before midnight of the third business day after signing — Wis. Stat. § 423.202 ('Customer's Right to Cancel' for consumer approval transactions; two copies of the notice required). Wis. Admin.

FTC Cooling-Off Rule (16 CFR Part 429) applies nationwide: 3 business days for door-to-door sales of $25+.

The law

  • Wis. Stat. § 423.202 — 3-business-day 'Customer's Right to Cancel' notice for consumer approval transactions
  • Wis. Admin. Code ch. ATCP 110 — Home Improvement Practices (contract contents; buyer cancellation rights on contractor default)
  • Wis. Stat. § 100.65 — 3-day cancellation for exterior-repair contracts tied to denied insurance claims

Contract notes

Third-party PPAs are in legal limbo in Wisconsin: the PSC's Dec 2022 declaratory ruling (Vote Solar / Northwind Renewable Energy Cooperative) held a residential third-party contract did NOT make the provider a public utility under Wis. Stat. § 196.01(5)(a), but no statute expressly authorizes third-party PPAs; utilities have denied interconnection for third-party-owned systems. DSIRE lists Wisconsin as having no residential PPA offerings. Lease vs PPA vs loan distinctions are unsettled —.

Enforcement watch: No 2024–2026 AG solar lawsuit found. Background: Sun Badger Solar (Waukesha) entered receivership ~2023 after dozens of customer suits over unfinished installs; WI DOJ represented the Dept. of Workforce Development on employee wage claims. Wisconsin (via the WI Economic Development Corporation, not AG Kaul) joined the Oct 2025 multistate Solar for All suit.

What to do next in Wisconsin

  1. Read your contract's cancellation clause tonight. Compare it against the state window: Before midnight of the third business day after signing — Wis. Stat. § 423.202 ('Customer's Right to Cancel' for consumer approval transactions; two copies of the notice required). Wis. Admin. Code ch. ATCP 110 (Home Improvement Practices) requires the 3-day notice in home-improvement contracts. FTC Cooling-Off Rule (16 CFR Part 429) applies nationwide: 3 business days for door-to-door sales of $25+.
  2. If the company never gave you a cancellation form, your federal 3-day clock may never have started — that's the loophole in our cooling-off guide.
  3. Past the window? Shift to the complaint path: where to file, and check whether savings were misrepresented (guide).
Get the notice written for you. The $39 SolarEscape Kit generates a cancellation letter citing Wis. Stat. § 423.202 — 3-business-day 'Customer's Right to Cancel' notice for consumer approval transactions, with your dates filled in — plus the complaint kit and bankrupt-installer playbook.
Not legal advice. This tool provides general information based on state statutes and the FTC Cooling-Off Rule as of October 2026. Laws change and every contract is different. For advice about your specific situation, talk to a consumer attorney or your state attorney general's office. We can't promise you can cancel — nobody can. What we do: tell you where the cancellation windows are, and what to do when they're closed.
