Colorado at a glance

Colorado passed a dedicated solar consumer protection law in 2025. For agreements signed on or after July 1, 2026, solar sellers must give standard disclosures and hold a recorded welcome call, and your three-day cancellation period doesn't start until that call happens. Colorado also keeps retail-rate net metering.

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 Colorado'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 Colorado'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

Colorado cancellation window

At least 3 business days, starting after the welcome call

If you buy a home solar or battery system under an agreement signed on or after July 1, 2026, you can cancel without financial penalty for at least three business days after you receive the signed agreement. The three days do not start until the company completes a required welcome call with you.

Conditions that matter

  • The company must explain your right to cancel out loud when you sign and tell you the exact last day you can cancel. The agreement must include a bold cancellation statement next to the signature line and a cancellation form.
  • The company may keep a nonrefundable deposit of up to $100 that it collected before receiving your signed agreement.
  • This cancellation right covers purchases. It does not cover leases or power purchase agreements, systems sold with a newly built home, or agreements signed before July 1, 2026.

These rules come from SB 25-299 (2025), which applies to agreements entered into on or after July 1, 2026. The welcome call must be in the language used in the sales presentation and must remind you of your right to cancel. Violations are deceptive trade practices under the Colorado Consumer Protection Act.

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 Colorado

Retail net metering with credits that carry forward

Colorado law requires utilities to offer net metering. Excess power is credited against future use, and credits carry forward month to month. At year end you can be paid for leftover credits or make a one-time choice to keep rolling them forward. Systems can be sized up to 120 percent of your average yearly use in investor-owned utility areas.

Check your Colorado solar contract

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

  • For agreements signed on or after July 1, 2026: you had a recorded welcome call.
  • You know the date of the welcome call, since your cancellation period runs from it.
  • You received the required disclosures before signing.
  • Savings estimates match your utility's net metering terms.

  4. Keep proof of every notice. Save emails, certified mail receipts, and the date you sent anything.

Colorado solar questions

What is a welcome call?

Under Colorado's 2025 law, the solar seller must call you after you sign to go over the key terms of your agreement, and record the call. Your three-day cancellation period doesn't start until that call happens.

My agreement was signed before July 1, 2026. Am I covered?

The new solar law doesn't apply, but the Colorado Consumer Protection Act and the general three-day home solicitation rule may still help.

Who do I contact about a Colorado solar company?

The Colorado Attorney General takes consumer complaints through Stop Fraud Colorado. Utility billing issues go to your utility first, then the Public Utilities Commission.
