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 Montana'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 Montana'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

Montana cancellation window

3 business days after signing

Montana's 2025 solar consumer law lets you rescind a home solar contract sold through a door-to-door solar sales agent by giving written notice within three business days after you sign. If you rescind on time, the contract ends, and the company cannot enforce it or file claims for labor and materials.

Conditions that matter

  • Send your notice in writing by email or certified mail to the person the contract names for cancellations. The sales agent must give you a written explanation of this right in all capital letters, with space for you to initial that you read it.
  • Covers solar electric systems, including battery storage, used for personal, family, or household purposes on a home you own or lease, when the sale was made door to door. The solar law does not set a refund deadline.
  • If the solar law does not apply, Montana's Personal Solicitation Sales Act may. For sales over $25 that a seller started by phone or in person away from its place of business, you can cancel in writing before the end of the third business day after signing (a mailed notice counts once it is in the mailbox), and the seller must return your payments within 10 days. That act does not apply if you started the contact, already knew the seller and what it was selling, or the goods cannot be returned in substantially the same condition.

This law (2025 House Bill 760) took effect when the governor signed it on May 13, 2025. It also bars solar companies and their agents from making deceptive statements about the costs, financing, or terms of a solar purchase or installation. The general door-to-door rules are in MCA 30-14-504 and 30-14-506.

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.

Where to get help in Montana

These are official agencies. Filing a complaint is free. An agency can investigate or mediate, but most cannot act as your lawyer or guarantee a refund.

Contractor licensing

Montana Department of Labor and Industry, Construction Contractor License (CCL) Program

Since January 1, 2026, construction contractors must hold a state license, which replaced the old registration. File complaints through the department's online complaint page; it enforces conduct such as fraud and misrepresentation but does not judge workmanship quality.

Visit the official page 406-444-6880

Consumer protection

Montana Department of Justice, Office of Consumer Protection

Takes complaints about contract disputes, billing, and deceptive advertising. Contact the business first, then send copies of your contract and receipts. Local calls go to 406-444-4500.

Utility billing and service

Montana Public Service Commission, Consumer Assistance Program

Contact your utility first. It cannot give legal advice and does not regulate rural electric cooperatives or municipally owned utilities.

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.
