Filing sunstrong solar lease complaints? You are not alone — and the Connecticut AG just opened an investigation.

SunStrong absorbed the residential solar lease portfolio originated under the SunPower brand and now services those contracts after SunPower's August 2024 Chapter 11 bankruptcy. On March 17, 2026, Connecticut AG William Tong issued a civil investigative demand and announced an open investigation into SunStrong Management following dozens of consumer complaints about unhonored warranties, ignored service requests, and a new $10/month fee for solar production data. Your lease did not vanish in the SunPower bankruptcy — and neither did your right to push back on the entity now collecting on it.

Check your SunStrong paperwork for these issues

A match does not prove wrongdoing, but it identifies the documents and representations that deserve closer review.

  • I have a residential solar lease or PPA originally signed with SunPower (pre-2020) that is now serviced by SunStrong.
  • SunStrong has failed to respond to a warranty claim, repair request, or production-shortfall complaint.
  • I have been billed a new monthly fee — including a $10/month charge for solar production monitoring or data access — that was not in my original lease.
  • My system has underperformed against the production guarantee in my original SunPower lease and SunStrong has not made me whole.
  • I am trying to sell or refinance my home and SunStrong has been unresponsive on the lease transfer or buyout.

How to identify SunStrong in your records

  • Original lease or PPA paperwork lists SunPower Capital, SunPower Corporation, or a SunPower-branded financing entity as the lessor.
  • Servicer correspondence now arrives from SunStrong Management or its sub-servicer (Launch Servicing took over billing on the SunStrong 2018-1 portfolio on August 1, 2024).
  • Lease term is typically 20 or 25 years with an annual escalator (commonly 0.99% to 2.9%).
  • Production guarantee language references a kWh-per-year baseline with a true-up obligation.
  • Account access historically went through the mySunPower portal, which SunStrong Management now operates.

Recurring SunStrong complaint patterns

Warranty Stranding

Production guarantees written by SunPower, ignored by SunStrong

The original SunPower lease promised a kWh production floor, with a true-up payment owed when the system underdelivered. Homeowners reporting underperformance to SunStrong since the SunPower bankruptcy describe months of silence, denied claims, or referrals to entities that no longer operate. The Connecticut AG specifically called out warranty non-performance as the lead allegation in its March 2026 investigation.

Where to check: Pull your annual production-guarantee statement and compare against your inverter's kWh log. A shortfall under your guarantee that has not been credited is the actionable fact.

Potential impact: Hundreds to low thousands per year of unpaid true-ups

New Fees

A $10/month charge for production data was not in your lease

Per the Connecticut AG announcement, SunStrong has been charging customers $10/month to access solar production data through what was previously a free SunPower customer portal. Your original lease almost certainly does not authorize a monitoring or data-access fee. Charging it anyway is a unilateral modification of a long-term contract — a textbook UDAP violation in most states.

Where to check: Search your original lease for any monitoring, data-access, or portal fee. If it is not there, the $10/month line item is unauthorized.

Potential impact: $120/year per customer, recoverable as restitution

Servicing Black Hole

The mySunPower portal works, but no one is on the other end

Customers describe submitting service tickets that vanish, calling support lines that loop back to voicemail, and waiting weeks for a return call on outages that are costing them real utility-bill dollars. The CT AG's CID specifically targets non-responsiveness to consumer complaints. If your system is down, every day SunStrong delays is recoverable damages — your utility bill is the running tally.

Where to check: Document every ticket number, every call attempt, every email. The paper trail of unanswered contact attempts is what a regulator or arbitrator needs.

Potential impact: Variable — equal to your utility offset times days down

Lease Transfer Friction

Selling your home? SunStrong is the bottleneck

Residential solar leases require lessor approval to assign to a buyer or to be bought out for a closing. Customers attempting to refinance or sell since the SunPower bankruptcy report SunStrong taking weeks or months to issue payoff quotes or transfer paperwork — long enough that closings die. A deal-killing delay caused by an unresponsive lessor is itself a documentable harm.

Where to check: Save every dated request for a buyout quote, transfer packet, or estoppel letter. Compare against your closing date.

Potential impact: Potential deal collapse + carrying costs of a delayed sale

Escalator Sticker Shock

Annual escalators that no one explained at signing

Many SunPower-originated leases include an annual payment escalator — frequently around 2.9% — that compounds across the 20- or 25-year term. After a decade, the lease payment can exceed what the original sales pitch projected for utility savings. Where the escalator was not adequately disclosed at signing, this is a misrepresentation claim that survives the change in servicer.

Where to check: Pull your original lease and locate the escalator clause. Multiply your year-one payment by (1 + escalator)^current year. If you are paying that much, the math is what it is — but the disclosure question is separate.

Potential impact: Compounding overcharge over the remaining lease term

Hardware Without Backstop

Inverter or panel failures with no operational warrantor

SunPower-issued workmanship warranties were issued by an entity that wound down in 2024. Manufacturer warranties on the panels or inverters may survive — particularly for legacy SunPower-branded hardware that was assumed by an acquirer — but the installer-side workmanship coverage is functionally orphaned. SunStrong's role is to service the lease, not to replace failed equipment under a vanished warranty.

Where to check: Identify the warrantor on each line of your warranty paperwork. Anything issued by SunPower Corporation specifically is unenforceable against an operating party.

Potential impact: Out-of-pocket replacement cost on a system you do not own

Public records and regulatory actions

Connecticut Attorney General (2026)

On March 17, 2026, AG William Tong announced new developments in the state's ongoing solar enforcement, including an open investigation into SunStrong Management LLC. His office issued a civil investigative demand on February 27, 2026, after receiving roughly 65 consumer complaints about SunStrong's failure to uphold warranties, non-responsiveness to consumer complaints, and the imposition of a $10/month fee to access solar production data.

Electric bills are through the roof right now and it makes sense that homeowners are looking to solar to save money — but they are running into companies that promise the world and then disappear when problems arise.

Connecticut AG press release, March 17, 2026

U.S. Bankruptcy Court, District of Delaware (2024)

SunPower Corporation filed for Chapter 11 bankruptcy in August 2024 and wound down its operations. The bankruptcy disrupted servicing for the residential solar lease and PPA portfolio that had been originated under the SunPower brand, accelerating the transfer of day-to-day customer-facing servicing to SunStrong Management and its appointed sub-servicer, Launch Servicing.

Frequently asked questions about SunStrong

Can I stop paying my solar loan if the system never worked?

Unilaterally stopping payment is risky — it triggers default, hits your credit, and gives the holder a head start on collection. The better move is a three-step sequence: (1) document the non-performance in writing (PTO date vs first-bill date, monitoring data, inspection failures), (2) preserve your right to assert the FTC Holder Rule (16 CFR § 433.2) defense against whoever currently holds the loan, and (3) get a written eligibility review BEFORE you change your payment behavior. TILA § 130 fee-shifting means the lender pays your attorney's fees when you prevail, so qualified disputes do not cost you out of pocket. The eligibility review is the right way to find out if your facts qualify.

Can I sue the solar lender if the installer is bankrupt?

Yes, in many fact patterns. The installer's bankruptcy stops claims against that specific entity, but the lender that financed your loan is a separate, usually solvent, target. Under the FTC Holder Rule (16 CFR § 433.2), the lender inherits liability for the same misrepresentations the installer made — false savings projections, fabricated tax-credit math, undisclosed dealer fees, signatures captured without time to read. Recovery under the Holder Rule is typically capped at amounts already paid into the loan, but in solar that frequently runs into the tens of thousands. Many homeowners assume their case dies with the installer and walk away — that is exactly what the lender's collections team hopes for. The eligibility review identifies whether your loan documents trigger Holder Rule liability.

What is the FTC Holder Rule and why does it matter for solar loans?

The FTC Holder Rule (16 CFR § 433.2) requires every consumer credit contract that finances goods or services to carry a clause subjecting the lender to all the same claims and defenses the borrower could raise against the seller. Translated to solar: if the installer lied to you, abandoned the install, or never energized the system, those claims travel to whoever currently holds your loan. The rule caps the recovery at amounts already paid into the loan, but in solar that frequently runs into the tens of thousands. The Holder Rule is the single most important lever a homeowner has when the original installer is bankrupt or unreachable — it lets you press the case against a solvent target instead of a corporate shell.

How long do I have to file a claim against a solar lender?

Deadlines vary by claim type and state, and missing them is irreversible. As a rough primer: federal Truth in Lending Act (TILA) damages claims usually run 1 year from the violation; TILA rescission is up to 3 years; the FTC Holder Rule cap is amounts paid; state Unfair and Deceptive Acts and Practices (UDAP) statutes typically run 2 to 4 years (Texas DTPA = 2 from discovery, Florida FDUTPA = 4, California CLRA = 3, North Carolina UDTPA = 4, with treble damages mandatory). FTC Holder Rule defenses to a lender's collection action have no statute of limitations on the defense itself — meaning if the holder sues you, you can raise installer-fraud defenses regardless of age. Do not guess at your deadline. The eligibility review computes the live limitations window for your specific loan and state in two minutes.

SunPower went bankrupt in 2024 — is my lease still enforceable?

Yes, on both sides. Your obligation to make lease payments survived the SunPower Chapter 11, and so did the lessor's obligations to you under that contract — including the production guarantee, warranty terms, and the limits on what fees can be charged. Servicing was handed to SunStrong Management with Launch Servicing as sub-servicer. The contract did not change, only the entity collecting on it. That distinction matters: if SunStrong is charging fees the original SunPower lease never authorized, or ignoring warranty terms the original SunPower lease promised, those are separate violations attributable to SunStrong specifically.

Can SunStrong start charging me a $10/month fee mid-lease?

Almost certainly not. The Connecticut AG's March 2026 investigation specifically calls out the $10/month production-data fee as one of the consumer-protection issues driving the case. Your original SunPower lease is the controlling document. If it does not authorize a monitoring or data-access fee — and the vast majority do not — the unilateral imposition of one is a contract breach and, in most states, an Unfair or Deceptive Acts or Practices (UDAP) violation. Document every month the fee has been charged; that running total is your restitution number.

What is the FTC Holder Rule and why should solar borrowers care?

The FTC Holder Rule (16 CFR § 433) requires every consumer credit contract that finances goods or services to carry a clause subjecting the lender to all the same claims and defenses the borrower could raise against the seller. Translated to solar: if the installer lied to you, abandoned the install, or never energized the system, those claims travel to whoever currently holds your loan. The rule caps the recovery at amounts already paid into the loan, but in solar that frequently runs into the tens of thousands. The Holder Rule is the single most important lever a homeowner has when the original installer is bankrupt or unreachable.

The installer that sold me the system went out of business. Is there anything left to do?

Yes. The installer's bankruptcy stops claims against that specific entity, but the lender that financed your loan is a separate, usually solvent, target. Under the FTC Holder Rule, the lender inherits liability for the same misrepresentations the installer made. Many homeowners assume their case dies with the installer and walk away — that is the result the lender's collections team is hoping for. The right move is to identify who currently holds your note and pursue the lender, not the dead installer.

My contract has an arbitration clause. Does that close the door?

Usually it opens a faster one. Most solar finance agreements force the homeowner into individual arbitration through JAMS or AAA. Lenders wrote those clauses to block class actions, but for an individual claimant the clause has a side effect they did not advertise: the lender pays the arbitration filing fee, your case is heard on its specific facts, and consumer-protection arbitrators tend to credit the kind of digital-signature, recording, and language-mismatch evidence that gets diluted in mass class settlements. Arbitration is often the higher-recovery path for the individual homeowner.

How do I know if my solar loan includes hidden dealer fees?

Check your Truth in Lending disclosure (TILA box) — specifically the 'Amount Financed' line. If that number is 20-30% higher than the system price the salesperson quoted, you almost certainly have an undisclosed dealer fee. For example, a $25,000 system becomes a $32,500 loan. The fee is paid by the lender to the installer at closing and buried in your loan principal, meaning you pay interest on it for 20-25 years. Request an itemized breakdown from the lender in writing; TILA requires accurate disclosure of finance charges.

Can I stop paying my solar loan if the system doesn't work?

Do not stop paying without legal guidance. The loan is with the lender (GoodLeap, Dividend, Mosaic, etc.), not the installer — and missed payments will damage your credit and may trigger acceleration (the full balance becomes due immediately). The correct approach is to assert your claims against the lender through the FTC Holder Rule or state UDAP statutes while continuing to pay, or under explicit advice from an attorney who has reviewed your case. Some homeowners negotiate payment suspensions during active disputes, but this requires formal legal action.

What happens to my solar warranty if the installer goes bankrupt?

If the installer files Chapter 7 (liquidation), the warranty is effectively worthless — there is no entity left to honor it. If the installer files Chapter 11 (reorganization), warranties may continue but service quality often degrades. In either case, the value of the lost warranty can be asserted as damages against the lender under the FTC Holder Rule. Document the original warranty terms, get repair quotes from third-party solar companies, and include the cost of a replacement warranty in your claim.

How long do I have to sue a solar company or lender?

Statutes of limitations vary by state and legal theory, typically ranging from 2-6 years from the date you discovered (or should have discovered) the fraud. State UDAP statutes often have 2-4 year limits; TILA claims have a 1-year limit for damages but can be raised as a defense at any time. The clock usually starts when the fraud was or should have been discovered — not when you signed the contract. Because these deadlines vary dramatically and can be complex to calculate, consulting an attorney promptly is essential.

Can I refinance or sell my house with a solar loan or PPA?

It depends on the type of obligation. Solar loans (unsecured or UCC-1 secured) typically can be paid off at closing like any other debt — but if the payoff exceeds the system's value, you may need to bring cash to closing. Solar PPAs and leases transfer to the buyer, who must qualify; many buyers refuse homes with long-term PPA obligations. PACE assessments are the worst case — they attach as a property tax lien and many lenders (FHA, VA, Fannie Mae, Freddie Mac) will not approve loans on homes with outstanding PACE assessments. If a UCC-1 fixture filing appears on your title unexpectedly, challenge it through the process at [our UCC guide](/blog/remove-unauthorized-ucc-1-step-by-step).

Is solar panel fraud a crime? Can I press charges?

Some solar fraud rises to the level of criminal conduct — forgery (fake signatures), theft by deception, or criminal fraud. However, most solar disputes are civil matters handled through state consumer protection laws, not criminal prosecution. File complaints with your state AG and local law enforcement; the AG's consumer protection division can investigate pattern misconduct. Civil claims (suing for damages, loan cancellation, or rescission) are typically faster and more likely to produce recovery than waiting for criminal charges.

What does this cost me?

Solar Panel Scam Center charges nothing to review your situation. If your case has merit, we connect you with an independent consumer-protection attorney whose practice covers solar finance. Those attorneys typically work on contingency or under fee-shifting statutes — meaning you pay nothing out of pocket, and the defendant covers attorney's fees if you prevail under TILA, the FTC Holder Rule, or your state's UDAP. We are not a law firm; submitting an intake does not by itself create an attorney-client relationship.
