STATE SOLAR LAWS
Missouri's solar market is growing rapidly, especially in the St. Louis and Kansas City metro areas. This guide covers your cooling-off rights under Missouri law, the Missouri Merchandising Practices Act, net metering rules, and step-by-step exit options for Missouri homeowners dealing with solar contract issues.

Missouri homeowners who signed solar contracts through home solicitation generally have 3 business days to cancel under both state and federal law. Beyond that window, the Missouri Merchandising Practices Act (MMPA, RSMo Section 407.010 et seq.) — one of the strongest consumer protection statutes in the Midwest — may provide additional grounds for relief. Missouri's net metering rules and the state's Renewable Energy Standard also play important roles. We always recommend consulting a qualified Missouri attorney before taking action.
Missouri provides cooling-off protections for homeowners who signed solar contracts through door-to-door or home solicitation sales. With solar companies aggressively targeting Missouri's suburban communities, these protections are essential.
Under Missouri's home solicitation statutes, if a solar contract was signed at your home or at a location other than the seller's regular place of business, you generally have 3 business days to cancel. The seller must:
Important Missouri rule: Under RSMo Section 407.710, if the seller failed to provide the required cancellation notice, your right to cancel may extend until the proper notice is given. The seller must also refund all payments within 10 business days of receiving a valid cancellation notice. If the seller started work before the cancellation period expired, you may have extended rights and the seller may be required to restore your property at their expense.

The federal FTC Cooling-Off Rule (16 CFR Part 429) provides an additional 3-business-day cancellation window alongside Missouri's state protections. This dual protection ensures homeowners have recourse under both state and federal law.
Missouri law includes provisions that may protect homeowners from aggressive solicitation. Under various local ordinances in Missouri cities (including St. Louis, Kansas City, and Springfield), door-to-door solicitors may be required to obtain permits and follow specific rules. If a solar company violated local solicitation ordinances, this may support your case.
Time-sensitive: If you're within the cooling-off period, send your cancellation notice via certified mail immediately. Under Missouri law, act promptly to preserve your cancellation rights. How to cancel a solar contract →
The Missouri Merchandising Practices Act is one of the strongest consumer protection statutes in the Midwest. Under RSMo Section 407.020, it prohibits "the act, use or employment by any person of any deception, fraud, false pretense, false promise, misrepresentation, unfair practice or the concealment, suppression, or omission of any material fact in connection with the sale or advertisement of any merchandise." For solar homeowners, actionable conduct may include:
The MMPA is particularly powerful because:
Missouri's advertising laws, part of the broader MMPA framework, specifically target false or misleading advertising. Solar companies that advertise "free solar," "zero cost," or guaranteed savings without adequate disclosures may violate these provisions.
Missouri does not have a statewide contractor licensing requirement, but major municipalities — including St. Louis, Kansas City, Springfield, Columbia, and their surrounding counties — have local licensing and permitting requirements. Solar installations typically require both building and electrical permits. If your installer failed to obtain required local permits or licenses, this may affect the enforceability of the contract.
Missouri requires electrical work to be performed by licensed electricians in most municipalities. The Division of Professional Registration oversees statewide electrical licensing. Solar installations involve electrical work that must comply with local and state electrical codes. If your installer used unlicensed electricians, this may provide grounds for a complaint.
Check local requirements: Contact your city or county building department to verify whether your solar installer obtained required permits. In St. Louis County and Kansas City, permit violations are taken seriously and can support a contract challenge.

Missouri's net metering law, codified in RSMo Section 386.890, provides relatively favorable terms for solar homeowners:
Net metering in Missouri is important for solar contract disputes because:
Missouri's RES, established by voter initiative (Proposition C in 2008) and codified in RSMo Section 393.1025, requires investor-owned utilities to generate 15% of retail sales from renewable sources by 2021, with at least 2% from solar. This has driven significant solar development in Missouri, including both utility-scale and distributed solar. Solar companies sometimes misrepresent these requirements as mandating that homeowners install solar, which is false.
Ameren Missouri has offered solar rebate programs to help meet the RES solar carve-out requirements. These rebates have varied over time and have sometimes had waitlists or capacity caps. If a solar company promised a specific rebate amount that was not available at the time of your installation, or if the rebate was claimed by the solar company rather than passed through to you, this may be relevant to a dispute.
Under RSMo Section 137.100(5), solar energy systems may qualify for a property tax exemption in Missouri. However, the application of this exemption can vary by county assessor. If a solar company guaranteed a specific property tax treatment, verify with your county assessor's office whether the exemption applies to your system.
Missouri does not have a comprehensive solar access or solar rights law. However, RSMo Section 442.012 recognizes solar easements as voluntary agreements between property owners. Some local jurisdictions may have additional protections. If your solar company failed to disclose potential shading issues or HOA restrictions, this may be relevant to a contract dispute.
Missouri's growing solar market has produced increasing consumer complaints. Based on reports filed with the Missouri AG and MPSC:
Missouri homeowners report that solar companies overstated expected savings. While Missouri has retail-rate net metering, the state's moderate electricity rates and seasonal weather variations mean aggressive savings projections may not be realistic. Companies that project savings based on higher-rate markets or fail to account for Missouri's climate patterns may be providing misleading information.
The St. Louis metro area (including St. Charles, Jefferson, and St. Louis counties), Kansas City metro, Springfield, and Columbia are heavily targeted by door-to-door solar sales teams. Common complaints include salespeople who impersonate utility representatives from Ameren Missouri or Evergy, claim urgent deadlines for expiring rebates, or pressure homeowners to sign without adequate review time. These practices typically violate the MMPA.
Solar companies sometimes misrepresent the availability or amount of utility rebates (particularly Ameren Missouri's solar rebate program). If a specific rebate was promised but not delivered, or if the solar company retained the rebate that should have been passed through to you, this may constitute a deception under the MMPA.
Some Missouri solar loans include substantial dealer fees (20-30% of system cost) rolled into the financed amount without transparent disclosure. If undisclosed, this may violate TILA and the MMPA.
If you're a Missouri homeowner looking to exit your solar contract, the approach depends on your circumstances. Below is a general framework — we always recommend consulting a qualified Missouri attorney.
Important: We do not advise homeowners to stop making payments or breach contractual obligations. Missed payments can damage your credit and may result in additional legal liability. Continue making payments while exploring your exit options.
Contact your local building department to verify permits. Check electrical licensing through the Division of Professional Registration. Missing permits or licenses support a contract challenge.
File with the Missouri AG Consumer Protection Division and the MPSC. The Missouri AG has been active in pursuing solar-related consumer complaints.

Missouri-specific tip: The MMPA is one of the strongest consumer protection statutes in the Midwest. It does not require proof of intent to deceive, allows for punitive damages, and supports class actions. The Missouri AG's Consumer Protection Division has been particularly active in investigating solar complaints. If your solar company made misrepresentations, the MMPA provides powerful remedies.
