South Dakota Solar Panel Laws: Your Rights and How to Cancel a Solar Contract

South Dakota's solar market is relatively small compared to sunbelt states, but the Mount Rushmore State still sees residential solar installations and the contract disputes that sometimes accompany them. South Dakota's consumer protection framework, while not as solar-specific as some states, provides meaningful protections for homeowners who may have been misled during the solar sales process. This guide covers the key South Dakota laws affecting solar consumers, your cancellation rights, and your exit options.

Right to Cancel: South Dakota's Cooling-Off Period

If you signed a solar contract in South Dakota through a door-to-door or in-home sales transaction, you generally have a right to cancel within a limited window under federal and state law.

Federal FTC Cooling-Off Rule

The FTC's Cooling-Off Rule (16 CFR Part 429) provides a 3-business-day right to cancel for sales made at your home. This applies to most door-to-door solar sales where a representative visited your residence. The cancellation window extends until midnight of the third business day after signing.

South Dakota Door-to-Door Sales Statutes (SDCL § 37-24-5.1 through § 37-24-5.7)

South Dakota's door-to-door sales provisions sit inside the Deceptive Trade Practices and Consumer Protection chapter at SDCL § 37-24-5.1 through § 37-24-5.7. A "door to door sale" is generally defined at SDCL § 37-24-5.1 as any sale, lease, or rental of goods or services with a purchase price of $25 or more, under single or multiple contracts, where the seller or a representative personally solicits the sale and the buyer's agreement or offer to purchase is made somewhere other than the seller's place of business. The definition expressly reaches sales made in response to or following an invitation by the buyer, which typically covers a solar appointment the homeowner set after an initial call or online lead.

Under SDCL § 37-24-5.3, the seller must give the buyer a completed receipt or contract copy carrying, in ten-point bold face type, the statement: "YOU, THE BUYER, MAY CANCEL THIS TRANSACTION AT ANY TIME PRIOR TO MIDNIGHT OF THE THIRD BUSINESS DAY AFTER THE DATE OF THIS TRANSACTION." The seller must also tell the buyer of that right orally at signing, and may not misrepresent it. The seller is generally required to:

• Furnish a completed, detachable "NOTICE OF CANCELLATION" form in duplicate, attached to the contract or receipt (SDCL § 37-24-5.4)
• Fill in the seller's name and business address, the transaction date, and the deadline date, which may not be earlier than the third business day after the transaction
• Refrain from including any confession of judgment or any waiver of the buyer's cancellation rights (SDCL § 37-24-5.5)
• Honor a valid cancellation notice and refund all payments, return trade-ins and negotiable instruments, and terminate any security interest, generally within ten business days of receipt (SDCL § 37-24-5.6)

On the statutory form, cancellation is generally made by mailing or delivering a signed and dated copy of the cancellation notice, or any other written notice, or by sending an electronic notice, to the seller at the seller's place of business, so that it is sent not later than midnight of the deadline date. There is no age-based or senior-citizen extension in these sections, and the window is three business days regardless of the purchase price or whether the transaction is cash or financed.

Note that SDCL § 37-24-5.2 carves several transactions out of the definition, including a sale in which the buyer already has a right of rescission under the federal Truth in Lending Act (15 U.S.C. § 1635), which may apply where a solar loan takes a security interest in the home, and a sale made after prior negotiations during the buyer's own visit to the seller's fixed permanent retail location. Which carve-out, if any, applies to a particular solar agreement is a fact question for a qualified attorney.

What Qualifies as a Door-to-Door Sale in South Dakota

Under SDCL § 37-24-5.1, the protections generally apply to sales personally solicited by the seller or a representative where the buyer's agreement is made away from the seller's place of business. This typically includes:

• Unsolicited door-to-door sales visits by solar representatives
• In-home sales presentations, including those arranged via phone or online lead
• Sales at temporary commercial locations

SDCL § 37-24-5.2 excludes certain transactions, including sales made after prior negotiations during the buyer's visit to a fixed permanent retail location, transactions conducted and consummated entirely by mail or telephone with no other contact, and sales where the buyer already has a federal right of rescission. However, many solar contracts involve in-home presentations even when initial contact originated differently, and the statute expressly covers sales that follow an invitation by the buyer.

South Dakota Consumer Protection Laws for Solar

South Dakota Deceptive Trade Practices and Consumer Protection Act (SDCL 37-24)

The South Dakota Deceptive Trade Practices and Consumer Protection Act is the state's primary consumer protection statute. It prohibits deceptive acts or practices, unconscionable acts, and false advertising in consumer transactions. In the solar context, violations may include:

• Misrepresenting the cost savings a solar system will generate
• Failing to disclose material terms such as escalator clauses, UCC liens, or transfer restrictions
• Making false claims about equipment quality, warranties, or performance guarantees
• Marketing solar leases or PPAs as "free solar" or "government programs"
• Engaging in bait-and-switch sales tactics
• Misrepresenting the nature of the financial arrangement

Under SDCL 37-24, the Attorney General may bring enforcement actions, and consumers may seek actual damages, injunctive relief, and in some cases, attorney's fees. The South Dakota AG has historically been active in pursuing consumer protection enforcement, which can provide leverage for consumers with documented complaints.

In our assessment, South Dakota's consumer protection framework provides moderate protections. While the Deceptive Trade Practices Act covers the key categories of solar sales misconduct, the state does not provide for statutory treble damages like some other states, which may somewhat reduce leverage in negotiations.

South Dakota Attorney General's Consumer Protection Division

The South Dakota Attorney General's Consumer Protection Division investigates consumer complaints and can take enforcement action against businesses engaged in deceptive practices. Filing a complaint creates an official record and may trigger mediation or investigation. The division has a dedicated consumer complaint hotline and online filing system.

South Dakota Contractor Licensing

South Dakota does not have a statewide general contractor licensing requirement, which is somewhat unusual among states. However, electrical work associated with solar installation typically requires a license. Key points:

• Electrical contractors must hold appropriate state or local licenses
• Some municipalities in South Dakota have their own contractor licensing requirements
• Building permits are generally required for solar installations
• Verify your installer's credentials through local licensing authorities and the SD Secretary of State's business records

South Dakota Warranty Protections

South Dakota recognizes both express and implied warranties under the Uniform Commercial Code (SDCL Title 57A). If your solar system was sold with express warranties regarding performance, output, or quality that have not been met, you may have claims for breach of warranty. Implied warranties of merchantability and fitness may also apply.

Solar-Specific Regulations in South Dakota

Net Metering in South Dakota

South Dakota's net metering landscape is less developed than many other states. The South Dakota Public Utilities Commission has established some rules regarding customer-owned generation, but there is no robust statewide net metering mandate comparable to states like California or New Jersey.

South Dakota Public Utilities Commission (PUC)

The South Dakota PUC regulates investor-owned utilities in the state. The PUC oversees utility rates, interconnection standards, and customer generation policies. For solar consumers, the PUC may be a resource for resolving disputes related to interconnection, billing, or utility solar programs.

Third-Party Solar Ownership in South Dakota

South Dakota's regulatory environment regarding third-party solar ownership (leases and PPAs) is not as clearly defined as in some other states. Questions may arise about whether third-party solar arrangements constitute the sale of electricity by an unregulated utility. If you have a solar lease or PPA in South Dakota, consulting a state attorney about the specific legal classification of your agreement is particularly important.

Property Tax Exemption for Solar

South Dakota offers a property tax exemption for renewable energy systems, including solar. Under SDCL 10-6-35.8 through 10-6-35.22, qualifying solar energy systems may be exempt from property tax assessment for a period of time. While this does not directly affect contract exit options, it is a relevant consideration for the overall economics of solar ownership in the state.

Solar Access and Easements

South Dakota has solar easement provisions (SDCL 43-13-17 through 43-13-19) that allow property owners to create voluntary solar easements to protect access to sunlight. These are negotiated easements rather than automatic solar access rights. South Dakota does not have a statewide law restricting HOAs from limiting solar installations, so homeowners in HOA communities should review their covenants and restrictions.

Common Solar Contract Issues in South Dakota

Based on our research, solar contract disputes in South Dakota, while less common than in high-volume solar states, typically involve these issues:

How to Exit a Solar Contract in South Dakota

If you need to get out of a solar contract in South Dakota, here is a general step-by-step framework. Results vary by individual situation, and we recommend consulting a qualified South Dakota attorney before taking significant action.

Step 1: Review Your Contract Thoroughly

Read your entire solar agreement, including all exhibits, addendums, and fine print. Identify the type of agreement (lease, PPA, or loan), the cancellation provisions, buyout terms, escalator clauses, and any performance guarantees. Note the company name and all critical deadlines.

Step 2: Determine If You Are Within the Cooling-Off Period

Under SDCL § 37-24-5.3, the deadline is generally midnight of the third business day after the date of the transaction. If you are still inside that window after an in-home sale, mail, deliver, or electronically send a signed and dated written cancellation notice to the seller's place of business right away, and keep proof of the date. If the seller failed to provide the required cancellation notice and NOTICE OF CANCELLATION form, consult an attorney about whether your cancellation window remains open. Cancellation guide →

Step 3: Document Everything

Gather all documentation related to your solar purchase:

• The signed contract and all amendments or addendums
• Sales brochures, presentations, and marketing materials
• All email, text message, and written correspondence
• Utility bills before and after solar installation
• Photos of the installation and any damage
• Notes on verbal representations made by the sales team

South Dakota is a one-party consent state for recording phone calls, so recordings of your own conversations with the solar company are generally permissible under state law.

Step 4: Identify Potential Legal Grounds

Common legal grounds for solar contract exits in South Dakota include:

• Deceptive practices under the SD Deceptive Trade Practices Act (SDCL 37-24)
• Violations of the door-to-door sales requirements (SDCL § 37-24-5.3 through § 37-24-5.6)
• Breach of contract or breach of warranty
• Fraud or misrepresentation
• Failure to disclose UCC liens or material contract terms
• Licensing violations (electrical or local contractor licenses)

Step 5: File a Complaint with the South Dakota Attorney General

File a formal complaint with the South Dakota Attorney General's Consumer Protection Division. This creates an official record, may prompt the solar company to negotiate, and helps the AG identify patterns of abuse. Call (605) 773-4400 or toll-free (800) 300-1986, or file online through the SD AG website.

Step 6: Evaluate Your Exit Options

Based on your specific circumstances, your primary exit options in South Dakota include:

1. Contract buyout: purchasing the system per the terms in your agreement
2. Transfer to a new homeowner: if selling, the buyer may assume the agreement (selling with solar guide →)
3. Negotiated settlement: leveraging documented violations to negotiate a release or reduced buyout
4. Legal action: pursuing rescission or damages through South Dakota courts (find a solar lawyer →)
5. Professional exit service: hiring a solar contract exit specialist (see our rankings →)

Step 7: Consult a South Dakota Attorney

We always recommend consulting with a South Dakota-licensed attorney experienced in consumer protection and contract disputes. Given the relatively small solar market in South Dakota, finding an attorney with specific solar contract experience may require looking at firms with broader consumer protection or contract law expertise.
