Solar Cancellation Laws by State

Start with the federal floor, then find your state

A solar salesperson who got your signature at the kitchen table is hoping you never look this up. If that is how you bought, you have at least three business days to cancel, in every state, under the FTC Cooling-Off Rule at 16 CFR 429.1. The rule covers consumer goods and services of $25 or more sold somewhere other than the seller’s own place of business, and its exclusions are real property, insurance and securities. A rooftop system is goods and labor, not real property, so the rule reaches it. That is the floor, and nothing a salesperson says on the way out the door takes it away.

What the states add is smaller and stranger than the fifty-row tables published by solar cancellation companies suggest. Those tables come from outfits that want to sell you an exit, which is reason enough to check the statute yourself. We did not trust anyone else’s summary. Every one of the 51 rows below was read from the statute itself, in the state’s own code where its site would open and otherwise on Justia or FindLaw, and then read a second time, section by section, before this page was written. The second read changed two rows.

What you need to know before the table. Only two states give every buyer more than three days: Alaska, with five business days for any door-to-door sale, and Texas, with five business days for any residential solar purchase or lease signed on or after September 1, 2025, whether or not it was sold at your home. Two states give older buyers more: California gives a buyer 65 or older five business days, and North Dakota gives a buyer 65 or older fifteen. Nine states count Saturdays. Ten states have acts that reach only credit sales, so a cash buyer there has the federal rule and nothing else. Three states have solar-specific cancellation statutes in force, and two more have solar disclosure laws that point at the general window.

The counting-rule trap

This is where sellers and finance companies find room to argue, so get it right. The federal rule counts business days, which means Saturdays, Sundays and federal holidays do not count. Sign on a Friday and your three business days are Monday, Tuesday and Wednesday, so the deadline is midnight Wednesday.

Washington’s statute says something that sounds the same and is not. RCW 63.14.154 gives you until midnight of the third day “excluding Sundays and holidays.” Saturday is a day. Sign on a Friday and the count runs Saturday, Monday, Tuesday, so the state deadline is midnight Tuesday, and the notice has to be posted by certified mail by then. Arkansas writes its rule the same way. Florida, Indiana, Maryland, New York, Ohio and Rhode Island get to the same place by defining “business day” as every calendar day except Sunday and a list of holidays, and Nebraska’s court of appeals read the undefined term the same way in Flodman v. Robinson. In all nine you still hold the federal three business days, and a cancellation on Wednesday would still be good under federal law. But the state deadline is the one printed on the seller’s notice, and it is the one a finance company is likely to hold you to. It lands a day early, so treat it as the real one.

The clock trap runs the other way, and this one works against sellers. In most states the count starts the day you sign. In Colorado’s solar act it starts when you receive the signed agreement and not until the seller has made a required welcome call. In Indiana it starts on the later of the seller’s notice or the final agreement. In Nebraska and Wisconsin it starts when the seller hands you the cancellation notice, and in Illinois and Massachusetts it does not start until you have the notice form and a complete signed copy. In Utah it starts on the later of the transaction or delivery of the product. A seller who cut corners on the paperwork may have left your window open longer than the date on the form, and the seller owns that mistake.

The table

Verified 51 of 51. Unverified 0. Every row links to the statute text that was read, so you can check it yourself instead of taking a seller’s word. The Scope column tells you whether the state act reaches a cash sale and whether a solar-specific statute sits on top of it.

The ten states where a cash buyer has only the federal rule

Alabama, Georgia, Idaho, Mississippi, Missouri, New Jersey, Oklahoma, South Carolina, Washington and West Virginia wrote their home solicitation rights into consumer credit codes or retail installment acts, so the state right attaches to the financing, whoever knocked on your door. In Georgia the act reaches only a seller-financed installment sale. In New Jersey both acts reach only installment contracts, and the notice has to be postmarked by 5 p.m. of the third business day, not midnight. In Washington the section lives in the Retail Installment Sales Act and applies to a retail installment contract or charge agreement.

Two of the ten reach further than they look, which helps many solar borrowers. South Carolina and West Virginia extend their acts to a sale paid for by a loan whose lender is subject to your claims and defenses against the seller, which under the FTC Holder Rule describes most seller-arranged solar loans. If your installer handed you a financing application, those two state rights probably reach you. If you paid cash or brought your own bank, you are on the federal rule in all ten, which still gives you three business days and still requires the seller to cancel any security interest when you exercise it.

The solar-specific statutes

Texas Occupations Code chapter 1806, in force since September 1, 2025, gives five business days from execution to cancel any residential solar purchase or lease in the state, and section 1806.006 says the chapter wins over the general three-day rule in Business and Commerce Code chapter 601. The contract must print the last calendar date to cancel and an address or email for the notice, and if it does not, any reasonable written notice works.

Nevada’s NRS 598.98216, added in 2023, gives three business days for any purchase, lease or power purchase agreement for a distributed generation system, wherever it was signed, and allows the notice by email to the address on the contract’s cover page.

Colorado’s C.R.S. 6-1-1804(5), added by SB 25-299 effective August 6, 2025, gives at least three business days from receipt of the initial signed agreement to cancel a solar or battery purchase, and 6-1-1809(3) says the period does not begin to run until the seller conducts its welcome call. A nonrefundable deposit of up to $100 may be kept. This matters more in Colorado than elsewhere because the general Colorado act, C.R.S. 5-3-402, reaches only consumer credit sales.

Utah’s 13-52-207 does not add days but changes what the days are worth: the agreement is unenforceable until you get a signed copy in paper and electronic form, the retailer may not begin installation until four business days after providing it, and the contract must state the right to cancel with an email and mailing address for notice. Arizona’s 44-1763 and California’s Business and Professions Code 7169 are disclosure statutes that require the contract to state the cancellation right you already have. Connecticut’s Public Act 26-16, effective October 1, 2026, names residential solar and storage systems as consumer goods under the Home Solicitation Sales Act, adds seller registration, a consumer handbook, salesperson ID cards and a 9 a.m. to 7 p.m. limit on in-person solicitation, and keeps the window at three business days. Virginia passed a solar disclosure law in 2026 that takes effect January 1, 2027; we could not read its enacted text this run, and no report we found says it changes the three-day window.

Where the act would not have helped anyway

Every state act carries exclusions, and a seller looking for a way to deny your cancellation will start there. We read each list. The common ones are real property, insurance, securities, a sale that followed prior negotiations at the seller’s store, a repair visit you asked for, and a transaction that already carries a Truth in Lending rescission right, which is a loan secured by your home rather than by the panels. None of those describe a rooftop system sold at your door, with one exception worth knowing. Arizona, Indiana, Maine and Montana limit their acts to a solicitation you did not invite, so a visit you booked through an online lead form may fall outside the state act in those four states and leave you on the federal rule. The federal rule has no such limit, so a lead form does not strip you of your three days.

Hawaii and Minnesota went the other way and closed that argument off for sellers: Hawaii defines goods to include things that will be affixed to real property, and Minnesota’s definition expressly includes improvements to real property. Maine bars the seller from affixing anything to your real estate while the cancellation period runs, and Massachusetts, Ohio and Utah bar a seller from starting the work during the period or, in Utah, for four business days after handing over the signed contract.

What the second read changed

Two rows moved on the section-level re-read, both of them rows that had been verified in an earlier run. We show our work because you should be able to check our reading, and anyone else’s, including a cancellation company’s. Florida’s 501.025 says “third business day,” and the first read stopped there. The definitions section, 501.021, says a business day is any calendar day except Sunday or a federal holiday, so Florida joined the nine states where Saturday counts. Washington’s day count and counting rule held, but RCW 63.14.154 opens with “retail installment transaction,” and the first read had not carried that into the row: the Washington right belongs to a buyer on a retail installment contract, and a cash buyer there has the federal rule. Neither change makes the earlier rows wrong about the number of days. Both change the answer a reader would get on a Friday signing or a cash sale, which is the point of reading the whole section.

How to use this

Find your state, read the Scope column before the Window column, and then read the Clock column. Do not let a scheduling call, a welcome email or a salesperson’s reassurance carry you past the deadline. Send your notice by the method the statute or your contract names, keep proof of the sending, and send it a day before the earlier of the two deadlines, state or federal. The deadline calculator reads the same data as this table and returns a conservative act-by date, and the cancel before installation page has the notice wording and the contract clause that can keep a no-cost exit open long after every statutory window has closed. This is general information about the statutes as they read on September 16, 2026, not legal advice, and a state legislature can change any row above.
