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 Maine'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 Maine'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

Maine cancellation window

3 business days after signing

Maine's Consumer Solicitation Sales Act lets you cancel a purchase within three full business days after the day you sign, if a salesperson contacted you in person or by phone away from the seller's place of business and you did not ask for the contact. A 2026 change spells out that solar energy equipment and shares in community solar (net energy billing) projects are covered.

Conditions that matter

  • Cancel by written notice sent by ordinary mail to the seller's address in the contract. It counts once mailed, and no special form is needed. The contract must be in writing, signed, dated, and must explain your right to cancel.
  • The seller cannot start installing equipment that will be permanently attached to your home while you can still cancel. It must refund all payments, including any down payment, within 15 days of your notice. If the seller does not pick up delivered goods within 20 days after you cancel, you can keep them.
  • Does not apply to sales under $25, insurance, certain securities, and certain lender credit sales. If the seller financed the sale itself (a consumer credit sale), the similar home solicitation rule in the Maine Consumer Credit Code applies instead: you can cancel in writing until midnight of the third business day after signing, and work on items attached to your home cannot begin during that time.

Solar equipment was added to the law's definition of merchandise by Public Law 2025, chapter 575, an emergency law enacted in March 2026. That law also requires anyone selling or leasing home solar equipment to give you a standard written disclosure, including termination terms, before the sale or lease starting June 1, 2026 (35-A M.R.S. §3218). The credit sale rule is 9-A M.R.S. §3-502.

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.

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.

Questions to ask

  • Which agreement am I trying to cancel or change, and who is the other party to it?
  • What does my agreement say about cancellation, notice, and where to send it?
  • Did the seller give me the cancellation notice and disclosures required in my state?
  • Is my loan separate from my installation contract, and what happens to it if the contract is canceled?
  • Was a dealer fee built into my loan? Estimate it with our calculator.
