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 New Hampshire'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 New Hampshire'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

New Hampshire cancellation window

3 business days

New Hampshire has no solar-specific cancellation law that we found. Its home solicitation law lets you cancel a sale of goods or services of $150 or more until midnight of the third business day after the transaction, when the seller solicits and makes the sale anywhere other than its permanent place of business, such as your home.

Conditions that matter

  • Cancel by written notice mailed to the seller, preferably by certified or registered mail, or by returning the goods in person within the three business days. Keep a copy.
  • The seller must return your payments, any trade-in, and any note or other evidence of debt within 15 days of cancellation.
  • If the seller has already altered your property, for example by starting installation, you are still entitled to a full refund with no deduction for the work. If the property can reasonably be restored, you may instead demand that it be restored.
  • Does not apply to sales under $150 or to sales made at the seller's permanent place of business.

The seller must give you a receipt and contract copy with its name and address, the date, and a boldface cancellation notice near your signature. A violation is an unfair or deceptive act under the Consumer Protection Act (RSA 361-B:3). The law covers sales of goods or services, so whether it reaches a solar lease or power purchase agreement is not clear.

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.

Guides for your situation

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.
