Connecticut Solar Panel Laws: Your Rights & How to Exit a Solar Contract

Connecticut homeowners who sign solar contracts generally have until midnight of the third business day to cancel under both the FTC Cooling-Off Rule and Connecticut's Home Solicitation Sales Act (Conn. Gen. Stat. Section 42-134a et seq.). The operative right-to-cancel provision is Conn. Gen. Stat. Section 42-137, and the seller's notice duties are set out in Conn. Gen. Stat. Section 42-135a. Beyond that window, Connecticut's Unfair Trade Practices Act (CUTPA, Conn. Gen. Stat. Section 42-110a et seq.), widely considered one of the most powerful consumer protection statutes in the nation, may provide additional grounds for cancellation. Connecticut's net metering rules and PURA oversight further protect solar consumers. We always recommend consulting a qualified Connecticut attorney before taking action.

Right to Cancel / Cooling-Off Period in Connecticut

If you recently signed a solar contract in Connecticut, your most immediate protection is the cooling-off period. Connecticut law provides specific protections for home solicitation sales that work alongside the federal FTC rule.

Federal FTC Cooling-Off Rule (3 Business Days)

The FTC's Cooling-Off Rule (16 CFR Part 429) generally provides Connecticut homeowners with 3 business days to cancel a sale that occurred at your home or away from the seller's permanent place of business. Door-to-door solar sales are common throughout Connecticut: particularly in the Hartford, New Haven, Stamford, and Bridgeport metro areas.

Under this rule, the solar company is generally required to:

• Provide you with two copies of a cancellation form at the time of sale
• Inform you of your right to cancel within 3 business days
• Process your cancellation and refund any payments within 10 business days

Connecticut Home Solicitation Sales Act

Connecticut's Home Solicitation Sales Act is codified at Conn. Gen. Stat. Section 42-134a et seq. The operative cancellation right is Conn. Gen. Stat. Section 42-137, which generally provides that the buyer may cancel a home solicitation sale until midnight of the third business day after the day the buyer signs the agreement.

Several details of the Connecticut rule are worth understanding:

• How days are counted. Under Conn. Gen. Stat. Section 42-134a, a "business day" is generally any calendar day except Sunday and nine named holidays (New Year's Day, Washington's Birthday, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving Day and Christmas Day). Saturdays generally do count as business days in Connecticut, so the window can close sooner than homeowners expect.
• Cutoff time. Midnight of the third business day, not 5 P.M.
• How notice is given. Under Section 42-137, cancellation generally occurs when the buyer gives written notice to the seller at the address the seller specified for cancellation, or when that written notice bearing that address is deposited in a mailbox. Notice is generally effective on mailing rather than on receipt. Any writing that shows an intention not to be bound is generally sufficient.
• Age. Connecticut's statute does not appear to contain a senior-citizen or other age-based extension of the window.
• Scope. The act generally reaches both cash and credit transactions and excludes only sales where the purchase price does not exceed twenty-five dollars, so a residential solar sale is typically well within its reach.

Conn. Gen. Stat. Section 42-135a separately sets out the seller's duties. Sellers must generally give the buyer a fully completed contract in the language of the sales presentation containing 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," must attach a detachable, duplicate "NOTICE OF CANCELLATION" form, and must orally inform the buyer of the right to cancel. Failure to provide the required notice is a violation of Connecticut law and may affect the enforceability of the contract and your cancellation rights.

There is also an important Connecticut-specific overlay. Under Conn. Gen. Stat. Section 20-429(e), each home improvement contract is generally considered a home solicitation sale under chapter 740. In our assessment, that means a residential solar installation that qualifies as home improvement work may carry these cancellation rights even if the contract was not signed at your home.

Connecticut Statute of Limitations

For breach of contract claims in Connecticut, the statute of limitations is generally 6 years under Conn. Gen. Stat. Section 52-576. For CUTPA claims, the limitation is typically 3 years. For fraud, the limitation is generally 3 years from discovery. Act promptly to preserve your legal options.

Connecticut Consumer Protection Laws Relevant to Solar

Connecticut Unfair Trade Practices Act (CUTPA)

CUTPA (Conn. Gen. Stat. Section 42-110a et seq.) is widely considered one of the most powerful consumer protection statutes in the United States. Unlike many state consumer protection laws that require specific types of deceptive conduct, CUTPA broadly prohibits unfair or deceptive acts or practices in the conduct of any trade or commerce. This broad scope makes it a particularly effective tool for solar contract disputes.

Under CUTPA, homeowners may have grounds for legal action if the solar company engaged in:

• Unfair acts or practices: conduct that is immoral, unethical, oppressive, or unscrupulous, even if not technically illegal under other laws
• Deceptive acts or practices: including misrepresentations about energy production, savings, contract terms, or available incentives
• Practices that cause substantial injury: that consumers could not reasonably avoid and that are not outweighed by countervailing benefits

CUTPA remedies are expansive: consumers may recover actual damages, and courts have discretion to award punitive damages. Attorney's fees and costs are also recoverable under Conn. Gen. Stat. Section 42-110g. Courts may also issue injunctive relief.

Connecticut Home Improvement Act

Solar installations in Connecticut may be subject to the Home Improvement Act (Conn. Gen. Stat. Section 20-418 et seq.). Conn. Gen. Stat. Section 20-420 generally requires home improvement contractors and salespersons to hold a certificate of registration from the Department of Consumer Protection. Conn. Gen. Stat. Section 20-429 sets out the required contract provisions, including that the contract be in writing, be signed by both parties, contain the entire agreement, state the transaction date, give the contractor's name, address and registration number, include starting and completion dates, and contain notice of the owner's cancellation rights in accordance with chapter 740. Section 20-429(e) further provides that each home improvement contract is generally considered a home solicitation sale under chapter 740. Failure to comply with the Home Improvement Act may render the contract unenforceable and is also a per se violation of CUTPA.

Federal Truth in Lending Act (TILA)

If your solar agreement involves financing, TILA may provide additional protections including the right to rescind within 3 years if proper disclosures were not provided.

Solar-Specific Regulations in Connecticut

Net Metering in Connecticut

Connecticut has net metering provisions for residential solar customers. The state has been transitioning its compensation structure for distributed generation through proceedings at the Public Utilities Regulatory Authority (PURA). Key aspects:

• Net metering availability: Connecticut's electric distribution companies (Eversource and United Illuminating) are generally required to offer net metering to qualifying residential solar customers
• Compensation structure: PURA has been evolving the compensation framework for distributed generation. The specific credit rate may differ from the full retail rate depending on when you interconnected and current PURA orders
• Residential Renewable Energy Solutions (RRES): Connecticut has implemented programs to support residential solar adoption, which may affect how your system is compensated
• System size: residential net metering is typically available for systems meeting applicable size limits

Public Utilities Regulatory Authority (PURA)

PURA regulates Connecticut's electric distribution utilities and has jurisdiction over interconnection, rate structures, and distributed generation policies:

• Interconnection standards: governs how residential solar systems connect to the grid
• Rate design: PURA proceedings affect how solar customers are billed and credited
• Consumer complaints: PURA accepts complaints about utility practices related to solar interconnection and billing

Connecticut Solar Access and HOA Rules

Connecticut law generally supports solar access rights. Under the Common Interest Ownership Act, Conn. Gen. Stat. Section 47-261b(g) generally provides that an association may not adopt or enforce rules that would have the effect of prohibiting a unit owner from installing a solar power generating system on the roof of that owner's unit, provided the roof is not shared with another unit owner. That provision applies to a common interest community that is not a condominium or a cooperative. An association may still generally adopt rules governing the size and manner of affixing, installing or removing the system, the owner's upkeep and maintenance responsibilities, and a prohibition on installing on common elements.

Connecticut expanded these rights in 2025. Under Public Act 25-73, on and after January 1, 2026, a provision of a declaration or bylaws that prohibits or unreasonably restricts installing or using a solar power generating system on the roof of a qualifying single-family detached unit is generally unenforceable, with an association approval timeline and a limited board opt-out. Cooperatives are generally excluded, and a unit with a shared wall generally does not qualify. Because this area changed recently, we suggest confirming the current rule with a qualified Connecticut attorney.

Connecticut Property Tax Exemption

Connecticut provides a property tax exemption for qualifying residential solar energy systems under Conn. Gen. Stat. Section 12-81(57). That subdivision generally exempts a Class I renewable energy source installed to generate electricity for private residential use at a one-to-four family dwelling, for installations on or after October 1, 2007, where estimated annual production does not exceed the estimated annual load at the location. A separate local-option exemption for active solar heating and cooling systems appears at Conn. Gen. Stat. Section 12-81(56) and generally applies only where a municipality has adopted it. In practice, qualifying residential solar panels generally should not increase your property tax assessment. If a salesperson misrepresented the property tax implications, this could support a consumer protection claim.

Common Solar Contract Issues in Connecticut

Based on complaints to the Connecticut Department of Consumer Protection and the BBB, these are among the most common solar contract issues:

How to Exit a Solar Contract in Connecticut. Step by Step

If you're a Connecticut homeowner looking to exit your solar contract, below is a general framework. We always recommend consulting a qualified Connecticut attorney before taking action.

Step 1: Gather Your Documents

• Your original solar contract (lease, PPA, or loan agreement)
• Any marketing materials, brochures, or written estimates
• Records of verbal promises made during the sales presentation
• Electricity bills from before and after solar installation
• Any correspondence with the solar company
• Your solar system's actual energy production data

Step 2: Determine Your Cancellation Window

• Until midnight of the third business day after signing (home solicitation): Mail your written cancellation notice to the address the seller specified for cancellation, and keep proof. Reference the FTC Cooling-Off Rule and Conn. Gen. Stat. Sections 42-137 and 42-135a. Remember that Connecticut generally counts Saturdays as business days and excludes Sundays and nine named holidays
• Before installation: Check your contract for a pre-installation cancellation clause. Pre-installation cancellation guide →
• After installation: Proceed to Steps 3-5 below

Step 3: Review Your Contract for Exit Provisions

• Termination clause: early termination with buyout fee
• Performance guarantees: grounds for relief if system underperforms
• Transfer provisions: transfer to new owner if selling
• Home Improvement Act compliance: verify the contractor was registered and the contract includes all required terms

Step 4: Evaluate CUTPA Claims

Consult a Connecticut attorney about potential CUTPA claims. Common bases include:

• Overstated energy production or savings projections
• Failure to comply with the Home Improvement Act (per se CUTPA violation)
• Failure to disclose escalator clauses or their long-term impact
• Misrepresentation of net metering rates or compensation
• Failure to disclose UCC-1 lien filings
• Failure to provide proper home solicitation cancellation notices

Step 5: Send a Formal Demand

Your attorney will typically send a formal demand letter. The potential for punitive damages and attorney's fees under CUTPA creates strong leverage for negotiation.

Step 6: Consider Professional Exit Services
