SunStrong Management & SunPower Bankruptcy: Your Legal Rights [2026 Update]

Disclaimer: This article provides factual consumer education, public bankruptcy docket reporting, and regulatory updates. It does not constitute formal legal advice. If you are disputing charges or property liens with a solar loan or lease servicer, consult a licensed consumer-protection attorney in your state.

Overview

When residential solar giant SunPower Corporation filed for Chapter 11 bankruptcy in August 2024, hundreds of thousands of American homeowners were left in limbo. Promoters had sold SunPower systems on the promise of a "premier 25-year complete-confidence warranty" covering panels, inverters, monitoring, and roof penetrations.

Almost overnight, that corporate warranty vanished into bankruptcy liquidation.

Instead of relief, homeowners received letters informing them that their long-term Power Purchase Agreements (PPAs) and leases had been transferred to an unfamiliar entity: SunStrong Management. Across online forums, consumer complaint boards, and state regulatory dockets, borrowers report the same infuriating nightmare:

• Inverters and monitoring systems have stopped functioning, producing zero solar power.
• Repair tickets and warranty requests go unanswered or are outright rejected.
• SunStrong continues aggressively debiting bank accounts, enforcing annual price escalators, and reporting delinquent marks to credit bureaus for systems that do not work.

If your SunPower lease was transferred to SunStrong Management, you are not legally obligated to quietly pay for broken equipment. Federal consumer banking regulations, state deceptive trade practice statutes, and the FTC Holder Rule give you actionable leverage to fight back.

Key Takeaways

• Who SunStrong Is SunStrong Management is a third-party asset servicing entity that took over billing, portfolio collections, and lease administration for legacy SunPower accounts following SunPower's bankruptcy restructuring.
• The Dead System Trap Thousands of customers are paying monthly lease fees for non-producing solar arrays while simultaneously paying full utility electric bills—the exact "dual-bill disaster" they went solar to avoid.
• State AG Investigations Regulators, including the Connecticut Attorney General, have launched formal inquiries and issued Civil Investigative Demands (CIDs) regarding deceptive billing and maintenance abandonments by post-bankruptcy solar servicers like SunStrong and Spruce Power.
• Your Right to Revoke ACH Under federal Regulation E, you have the legal right to revoke automated bank debit permissions and force the servicer to substantiate billing through formal dispute procedures.
• FTC Holder Rule Protection An assignee cannot demand contract performance while failing to provide the promised consideration. Warranties and performance guarantees written into the original lease survive as affirmative defenses under the FTC Holder Rule against collections.

What Happened to SunPower?

For decades, SunPower was marketed as the gold standard of residential solar. The company manufactured high-efficiency Maxeon panels and packaged residential systems into 20- to 25-year leases and PPAs.

By mid-2024, burdened by hundreds of millions in debt, rising interest rates, accounting irregularities, and operational distress, SunPower collapsed. In August 2024, SunPower and several subsidiaries filed for Chapter 11 bankruptcy protection in the U.S. Bankruptcy Court for the District of Delaware.

During bankruptcy proceedings, SunPower sold off its assets in pieces. While third-party buyers acquired portions of the commercial and dealer networks, the massive portfolio of existing consumer leases and financing contracts was separated into servicing pools. SunStrong Management assumed administrative oversight and payment processing for tens of thousands of these residential accounts.

The Core SunStrong Complaints: What Homeowners Are Experiencing

Homeowners across the country have reported consistent, widespread failures since SunStrong took over their billing.

1. Inverters Fail and Monitoring Goes Dark

A solar system is useless without an operational inverter. When SunPower inverters destabilize or fail, systems shut off entirely. Furthermore, the proprietary mySunPower monitoring app has suffered widespread outages, leaving homeowners with no way to verify if their panels are generating power or feeding the grid.

2. The Warranty "Ghost Town"

When customers call SunStrong to report roof leaks, broken microinverters, or faulty wiring, they are routinely told that SunStrong is "merely the billing servicer, not the installer" and that warranty claims must be filed through the bankrupt SunPower estate or original equipment manufacturers (OEMs) like Enphase or SolarEdge. Homeowners find themselves caught in an endless bureaucratic loop where nobody takes responsibility for repairs.

3. Aggressive Collections on Non-Producing Systems

Despite producing zero electricity, SunStrong continues generating monthly invoices—often with built-in 2.9% annual escalator increases. Homeowners who cancel auto-pay face automated collections calls, late penalty fees, and threats of negative credit reporting.

4. Clouds on Real Estate Title (UCC-1 Liens)

SunPower routinely filed UCC-1 Financing Statements in county property records to secure equipment. When homeowners attempt to sell or refinance their homes, title companies flag these fixture filings. Homeowners report extreme difficulty getting SunStrong to coordinate timely lease assignments, payoffs, or UCC-3 termination filings, causing pending real estate transactions to collapse.

State Regulatory Scrutiny: The Connecticut AG Investigation

The widespread abandonment of post-bankruptcy solar customers has triggered government enforcement actions.

In Connecticut, Attorney General William Tong launched a formal inquiry into post-bankruptcy solar loan and lease servicers, including SunStrong and Spruce Power, issuing Civil Investigative Demands (CIDs) under the Connecticut Unfair Trade Practices Act (CUTPA). Regulators are examining whether servicers violated state law by:

• Demanding payment for solar energy that was never generated.
• Failing to provide maintenance and monitoring services mandated by lease contracts.
• Misrepresenting consumer obligations and harassing distressed borrowers.

Other state Attorneys General and consumer advocacy groups have warned that continuing to collect lease fees while disclaiming all warranty obligations constitutes an unfair and deceptive trade practice.

Pending Litigation & Debt Collection Scrutiny

In addition to state AG investigations, consumers have begun challenging servicer conduct in federal court. In Dalton v. SunStrong Management LLC (S.D. Cal. Case No. 3:25-cv-01960), consumers challenged aggressive collection practices under the Fair Debt Collection Practices Act (15 U.S.C. § 1692e). When solar servicers threaten credit destruction or dispatch collection agencies over accounts where equipment has completely failed, they face strict liability under federal debt collection and consumer credit reporting standards.

The $10 Monthly Data Fee & Unilateral Contract Modifications

A major point of contention highlighted in the Connecticut Attorney General's March 2026 inquiry is a newly introduced $10 monthly charge to access solar production monitoring data through customer portals.

• The Reality Original SunPower and Sunnova lease agreements provided basic production monitoring and portal access at no extra charge over the 20- or 25-year lease term.
• The Legal Conflict A loan or lease servicer cannot unilaterally invent new monthly fees that were never disclosed or agreed to in the original consumer credit agreement. Charging this fee without written contract authority constitutes an unauthorized debit and a deceptive practice under state consumer protection statutes.

The Sunnova & SunPower Guarantee Dilemma: Are Performance Payouts Canceled?

SunPower and Sunnova lease agreements frequently guaranteed minimum annual kWh generation floors, with a mandatory true-up refund if panels underproduced.

• What Servicers Say Multiple consumers report being told by servicer representatives that bankruptcy court orders released the entity from paying lost-production compensation, even while borrowers are compelled to continue paying in full.
• What Contract Law Requires While bankruptcy restructuring can discharge unsecured debts of the debtor corporation, an assignee or portfolio holder that steps into the shoes of the creditor cannot enforce the payment obligations of an executory consumer contract while repudiating its core performance promises. Homeowners facing massive generation deficits can assert failure of consideration and offset claims against monthly lease demands. For an actionable step-by-step response to servicer claims that court orders dissolved your true-up rights, read our dedicated legal breakdown on SunStrong dropping production guarantees and your payment rights.

Deceptive Servicing vs. Legal Reality

How to Fight Back Against SunStrong Management

If you are trapped in an unfair billing cycle with SunStrong, follow this systematic escalation strategy.

Step 1: Document the Failure of Consideration

You cannot build a dispute on verbal complaints. Create an indisputable evidentiary paper trail:

1. Utility Bill Comparison Pull 6 to 12 months of electric utility bills showing you are drawing 100% of your power from the grid with zero solar offset.
2. Monitoring Logs Screenshot error codes from your inverter, electrical panel, or monitoring app showing the system is offline or locked out.
3. Written Service Requests Log every phone call, email, and ticket submitted to SunStrong requesting repairs, noting dates, representative names, and lack of resolution.

Step 2: Revoke Automated Bank Debits (Regulation E)

Do not let a servicer automatically drain your checking account for non-functional equipment:

• Under the Electronic Fund Transfer Act (EFTA) and Regulation E (12 C.F.R. § 1005.10(c)), you have the right to stop payment on preauthorized transfers by notifying your bank at least three business days before the scheduled transfer.
• Send written notice to both SunStrong and your bank revoking ACH debit authorization. Notify your bank that any future debits from SunStrong are unauthorized.

Step 3: Send a Formal Notice of Contract Dispute

Mail a formal, written Notice of Dispute and Breach of Contract to SunStrong Management via Certified Mail with Return Receipt Requested:

• State clearly that the solar system has ceased operating and that SunStrong has failed to provide necessary maintenance and monitoring as required by the underlying lease agreement.
• Cite Failure of Consideration: explain that because the lessor has ceased providing solar energy, monthly lease charges are disputed in full.
• Demand that collections cease and that negative credit reporting be suspended pending resolution of the warranty breach.

Step 4: File Complaints with State and Federal Regulators

Regulatory pressure forces servicers to escalate consumer files to executive compliance departments:

• Consumer Financial Protection Bureau (CFPB) Submit an official complaint through the CFPB Complaint Portal under the loan/lease servicing category documenting unfair billing practices and billing on non-operational systems.
• State Attorney General File a complaint with your state's Consumer Protection Division, specifically referencing active state investigations into post-bankruptcy solar servicers like SunStrong and Spruce Power.
• State Contractor Licensing Board If unpermitted or shoddy repair technicians are dispatched, file a report with your state's licensing authority.

FAQ

Is SunStrong Management the same company as SunPower?

No. SunPower Corporation was the original manufacturer and installer that filed Chapter 11 bankruptcy in August 2024. SunStrong Management is a separate servicing entity that assumed management, billing, and collections for SunPower's residential lease and PPA portfolio following bankruptcy asset sales.

Why is SunStrong charging me a $10/month fee for solar production data?

The $10 monthly monitoring fee was introduced by SunStrong to access production data that was previously free on the mySunPower platform. Because original 20- or 25-year lease contracts rarely authorize new servicing or data fees, imposing this charge unilaterally is a primary focus of the Connecticut Attorney General's active investigation under unfair trade practice laws.

Does SunStrong have to honor Sunnova's or SunPower's original production guarantees?

While servicer representatives have claimed that bankruptcy courts eliminated lost-production compensation, an assignee cannot enforce long-term payment obligations while refusing the core consideration promised under the agreement. Homeowners whose systems generated significantly less electricity than contractually promised have legal grounds under the FTC Holder Rule and state contract law to demand fee reductions and offsets.

Can I cancel my SunStrong solar lease if my panels don't work?

Canceling a 20- to 25-year solar lease requires legal grounds, but total system failure combined with a servicer's refusal to repair constitutes failure of consideration and breach of contract. Homeowners with non-working systems can use written dispute notices and formal legal representation to negotiate lease terminations or buyouts.

Can SunStrong ruin my credit if I stop paying?

Servicers frequently threaten credit reporting when borrowers withhold payment. However, if you file a formal written dispute under the Fair Credit Billing Act (FCBA) or Fair Credit Reporting Act (FCRA), furnishers are legally required to mark the tradeline as "Account in Dispute" and are restricted from reporting false payment statuses while a documented dispute is actively pending.

What legal actions are pending against SunStrong Management?

As of 2026, the Connecticut Attorney General has an active civil investigation into SunStrong regarding warranty repudiation, unresponsive customer service, and unauthorized monitoring fees. Additionally, federal litigation such as Dalton v. SunStrong Management LLC (S.D. Cal.) has challenged post-bankruptcy collection and servicing practices under the Fair Debt Collection Practices Act.

What should I do if I am selling my house and SunStrong won't remove the lien?

Request a formal lease transfer packet or payoff statement immediately. If SunStrong fails to respond or delays the process, consult a real estate or consumer protection attorney to issue a formal demand letter threatening statutory damages for tortious interference with your real estate transaction.
