A Connecticut Solar Contract Signed at Your Kitchen Table Dies in Three Business Days. From Thursday You Can Kill It by Email.

Public Act 26-16 writes residential solar into Connecticut's Home Solicitation Sales Act on October 1, 2026. You get three business days, a ten-business-day refund clock, and a finance company that cannot say the fight is with the installer. The rules about the door knock itself do not arrive until 2027 and 2028.

If a solar rep gets your signature at the kitchen table in Connecticut this week, that contract is not finished.

From Thursday you have until midnight of the third business day to undo it, and the cancellation form stapled to your paperwork now tells you to send it by email.

Public Act 26-16 was signed on May 19, 2026 and takes effect October 1. It does not invent a solar law. It does something smarter. It drags solar into a law that has been sitting on the books for decades, the Home Solicitation Sales Act, by rewriting the definition of a “consumer good” to include any rooftop system of 25 kilowatts or less and any home battery.

Everything the old door-to-door law does, it now does to solar.

Here is what that buys you on Thursday.

Your contract has to carry the cancellation warning in boldface type of at least twelve points, plus a detachable notice of cancellation form filled out with the seller’s address and your deadline date. Cancel, and the seller has ten business days to hand back your payments and any note you signed. If crews already did work, the act says the seller “shall not be entitled to compensation” and has to put your property back the way it was. If nobody comes to collect the equipment within twenty days, it is yours, free.

The best line is in the financing. Every note you sign in a home solicitation sale has to say on its face, in capitals, THIS INSTRUMENT IS NOT NEGOTIABLE. Any transfer of it counts as an assignment only, and whoever buys it takes it subject to “all claims and defenses of the consumer against the seller arising under the provisions of this chapter.”

Translation: the finance company can no longer tell you your problem is with the installer. It bought your installer’s problems along with your loan.

Break the cancellation rules and it is an unfair or deceptive act under Connecticut’s Unfair Trade Practices Act. That is a private lawsuit, with actual damages, punitive damages, and attorney’s fees on the table.

Now the part the summaries skip.

The rules about the knock itself are not here. The 9 a.m. to 7 p.m. solicitation window starts February 15, 2027. The identification card and the state consumer handbook a rep is supposed to put in your hand start February 15, 2028, and the handbook does not even have to exist until December 31, 2027.

And on October 1, the penalty for violating the act drops. It was a class C misdemeanor. It becomes “a civil penalty of not more than five hundred dollars per violation.”

Five hundred dollars against a $30,000 sale is a rounding error. The unfair trade practices hook is the part with teeth. Use that one.

One catch worth more than the rest. This is a home solicitation sale only when you agree somewhere other than the seller’s place of business. Drive to their showroom to sign after talking it over at home, and the three days do not apply. If the rep offers to wrap it up at the office, that trip costs you your cancellation window. Sign at your own table or do not sign yet.

If you already signed this week, count the business days, email the cancellation tonight, screenshot the send, and mail a copy too. Then run the numbers cold with our solar calculator and the solar hub before anyone comes back.

Same day, same act, a separate clock: your lender owes you a payoff statement within seven days of a written request or it credits you $250. We covered that one here.

Frequently asked questions

What exactly changes in Connecticut on October 1, 2026?

Section 1 of Public Act 26-16 rewrites the definitions in the Home Solicitation Sales Act so that a 'consumer good' expressly includes any residential solar photovoltaic system or residential energy storage system. The act defines a residential solar photovoltaic system as equipment with a nameplate capacity rating of 25 kilowatts or less installed on the roof of a single-family home or a two-to-four unit dwelling, built to the Connecticut State Building Code. Sections 3 through 9 then rewrite the cancellation notice, the refund timing, and the penalties, all effective the same day.

How long do I have to cancel, and how do I do it?

Until midnight of the third business day after the day you sign. Saturdays, Sundays and legal holidays do not count as business days. The notice of cancellation form the seller must attach to your contract now tells you to 'sign, date, and send this notice of cancellation to the Seller by email, fax, or mail.' The separate cancellation section of the act also treats a notice as effective when it is deposited in a mailbox, so send the email for the timestamp and put a copy in the mail the same day.

What if the installer already did work before I canceled?

The act says that if the seller has performed any consumer services before cancellation, the seller 'shall not be entitled to compensation,' and if the work altered your property the seller must restore it to substantially as good condition as it was in. The seller also has ten business days after cancellation to return your payments and any note you signed, and if the seller does not come collect its equipment within twenty days, the act says the goods become yours with no obligation to pay for them.

When do the rules about door-to-door solicitation itself start?

Later than the headlines suggest. The 9 a.m. to 7 p.m. solicitation window applies on and after February 15, 2027, along with the seller's first annual report to the Department of Consumer Protection naming its financing and installation partners. The requirement to carry an identification card and hand you a state consumer handbook applies on and after February 15, 2028. The handbook itself is not due to be developed until December 31, 2027 or posted until January 15, 2028.
