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 Delaware'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 Delaware'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

Delaware cancellation window

3 business days after signing

Delaware's Home Solicitation Sales Act protects your right to cancel a door-to-door sale, lease, or rental of consumer goods or services of $25 or more until midnight of the third business day after the transaction. It covers sales the seller personally solicited where you agreed away from the seller's place of business, including visits you invited, so a solar sale or lease signed at your home is generally covered.

Conditions that matter

  • Cancel by mailing or delivering the signed and dated Notice of Cancellation, or any other written notice, to the seller's place of business. Business days exclude Saturdays, Sundays, and legal holidays. The seller must give you two copies of the cancellation form, tell you about your right out loud, and cannot ask you to waive it.
  • Within 10 business days after receiving your notice, the seller must refund all payments, return any trade-in, cancel any note you signed, and end any security interest. If the seller does not pick up delivered goods within 20 days, you can keep them.
  • Does not apply to sales after negotiations at the seller's retail store, sales where you have a federal Truth in Lending right to rescind, emergencies you started with a handwritten signed waiver, deals you started and completed entirely by mail or phone, repair visits you requested, or real property sales.

Delaware has no solar-specific cancellation law as of this check. Door-to-door sellers must also wear a state-issued ID card and may only solicit at homes between 9 a.m. and 8 p.m. (6 Del. C. §§4405 and 4406), and the seller cannot sell your note to a finance company before midnight of the fifth business day.

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 Delaware

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.

Installer and contractor complaints

Delaware Division of Professional Regulation (DPR)

Investigates licensed trades such as electricians, and unlicensed practice. It does not handle general contractors or billing and contract disputes, which go to the Consumer Protection Unit or the Justice of the Peace Court.

Visit the official page (302) 744-4500

Consumer protection

Delaware Department of Justice, Consumer Protection Unit

Tries informal mediation for most complaints. If that fails and no law was broken, you would need to work through a private attorney.

Visit the official page (800) 220-5424

Utility billing and service

Delaware Division of the Public Advocate, with the Public Service Commission

Contact your utility first. Unresolved billing or service complaints go to the Public Advocate, and you can then file a formal complaint with the Commission. Local number (302) 241-2555.

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.
