Connecticut at a glance

Connecticut strengthened its door-to-door law for solar in 2026. Public Act 26-16, effective October 1, 2026, puts residential solar and battery systems squarely under the Home Solicitation Sales Act, bars waivers of your cancellation rights, and makes violations unfair trade practices. Limits on door-knocking hours begin February 15, 2027. Connecticut ended net metering for new customers in 2022 and uses the Residential Renewable Energy Solutions program instead.

If you were misled, you have options

Being told your bill would disappear, that the system was free, that a tax credit would pay off the loan, or that you were only signing up for an inspection can all matter, even long after a cancellation window has closed.

  1. Your state's consumer protection law. Every state has a law against deceptive and unfair business practices. False promises about savings, costs, tax credits, or who you were dealing with may fall under Connecticut's law.
  2. Missing paperwork and disclosures. Many states require specific disclosures and a written cancellation notice. If you never received them, a deadline may not have started, or the contract may have other problems.
  3. Your lender may share responsibility. When a seller arranges your financing, federal rules often let you raise the same claims against the lender that you have against the seller, up to the amount you paid. Check your loan for a notice about the FTC Holder Rule.
  4. Official complaints. Complaints to Connecticut's agencies are free, create a record, and can lead to mediation or an investigation.
  5. Professional help. A solar attorney or solar exit company can review your documents and tell you which of these options fit your situation.

Your right to cancel

Connecticut cancellation window

3 business days after signing

Under Connecticut's Home Solicitation Sales Act, you can cancel until midnight of the third business day after the day you sign, when a seller personally solicits the sale and you sign somewhere other than the seller's place of business. Since October 1, 2026, the Act expressly covers residential solar and battery storage systems.

Conditions that matter

  • Saturdays, Sundays, and legal holidays do not count as business days. This changed on July 1, 2025. Some Department of Consumer Protection pages still say Saturday counts, so count conservatively.
  • Cancel in writing by email, fax, or regular mail to the contact details on the Notice of Cancellation. A mailed notice counts once it is in the mailbox, so keep a copy and proof of sending.
  • The seller must refund your payments within 10 business days, return any note you signed, and end any security interest or lien created by the sale.
  • If the seller does not give you the required cancellation notice, a copy of the agreement, or an oral explanation of your right to cancel, the agreement is not enforceable against you.
  • Does not cover deals negotiated beforehand at the seller's retail store, deals done entirely by mail or phone, or emergency work you requested and signed a written waiver for.

Public Act 26-16 (effective October 1, 2026) applies the Act to residential solar systems of 25 kilowatts or less and to battery storage on one- to four-unit homes, bars waivers of these rights, and makes violations unfair trade practices. It also requires lenders and providers to send a payoff statement or transfer documents within seven days of a written request, or credit $250. Limits on door-to-door hours begin February 15, 2027, and seller ID cards and a state solar handbook follow by February 15, 2028.

Canceling one agreement does not always cancel another. A separate loan, lease, or power purchase agreement can have its own terms, so check each document you signed. If the sale was made in Spanish or another language, read your rights when a contract is not in your language. To compare deadlines, see the cancellation period in every state.

How your utility credits solar in Connecticut

Residential Renewable Energy Solutions: Netting or Buy-All

Since January 1, 2022, Eversource and United Illuminating customers going solar choose between two tariffs. With Netting, your solar offsets your use and you also earn payments for renewable energy certificates. With Buy-All, the utility buys all of your system's output at a set rate. Rates are locked for 20 years. The program accepts new projects through 2027.

Check your Connecticut solar contract

Pull out your paperwork and look for these. Anything missing is worth noting in a complaint or showing to an attorney.

  • You received a Notice of Cancellation and the salesperson explained it out loud.
  • Nothing in the contract waives your cancellation rights (those waivers are void).
  • You know whether you're on the Netting or Buy-All tariff and what that means for savings.
  • Your installer is registered with the Department of Consumer Protection.
  • If you want to pay off or transfer the system, request the payoff statement in writing.

Before you contact anyone

  1. Gather every document you signed. The sales or installation agreement, any loan, lease, or power purchase agreement, and any change orders.
  2. Identify each company. The seller, installer, lender, and current servicer may be different businesses. Your latest statement shows who services your account now.
  3. Write down the timeline. When you were contacted, when you signed, when work started, and every promise made about savings or cost.
  4. Keep proof of every notice. Save emails, certified mail receipts, and the date you sent anything.
