SunPower Corporation, once one of the largest residential solar installers in the United States, filed for Chapter 11 bankruptcy protection on August 5, 2024. The company, which had installed solar systems on over half a million homes across America, cited mounting debt and operational challenges as the primary reasons for the filing.

• August 5, 2024: SunPower Corporation filed for Chapter 11 bankruptcy protection • August-September 2024: Company ceased new installations and began winding down operations • September 20, 2024: Shut down customer service (1-800-SUNPOWER), mySunPower app, and web portal • September 30, 2024: Complete Solar acquired SunPower assets for $45 million • April 2025: Complete Solar rebranded operations as "SunPower" (creating customer confusion) • Current Status: Original SunPower Corporation no longer operates; new entity operates under SunPower name

• Over 500,000 residential customers affected • $2.01 billion in outstanding debt • Approximately 1,800 employees laid off • Dealer network of 250+ installers disrupted • Customer support and monitoring systems shut down • Thousands of lease and PPA agreements in limbo

What Shut Down:

• 1-800-SUNPOWER customer service line (disconnected September 20, 2024) • mySunPower mobile app (discontinued) • mySunPower web portal (offline) • Email support system • Live chat support • Dealer support network

What This Means:

Customers can no longer contact SunPower Corporation for system monitoring, performance issues, maintenance questions, or warranty claims through the original company. The new entity (Complete Solar operating as "SunPower") has limited support for pre-bankruptcy customers.

The mySunPower app and web portal provided real-time monitoring of system performance, energy production, and alerts for issues. With these systems offline, customers have lost visibility into their solar system performance.

Monitoring Alternatives:

• Enphase Monitoring Upgrade: For systems with Enphase microinverters, Enphase offers a monitoring upgrade service. Contact: (510) 945-6752 or visit enphase.com/r/sunpower-upgrade. Cost: approximately $500-800. • Inverter Manufacturer Apps: Check if your inverter manufacturer (SolarEdge, Enphase, etc.) offers direct monitoring • Third-Party Monitoring: Independent monitoring solutions like Solar-Log, Locus Energy, or Deck • Utility Net Metering Portal: Basic production data may be available through your utility company

Understanding which warranties are still valid is critical for SunPower customers.

Still Valid:

• Maxeon Panel Warranties: If you have Maxeon-manufactured panels (most SunPower panels before 2024), the manufacturer warranty is still honored by Maxeon Solar Technologies (an independent company) • Inverter Warranties: Equipment warranties from manufacturers like Enphase, SolarEdge, or other inverter brands remain valid • Battery Warranties: Battery manufacturer warranties (Tesla, LG, etc.) are independent of SunPower • Component Warranties: Other equipment manufacturer warranties remain in effect

No Longer Valid:

• SunPower Corporation Installation/Workmanship Warranty • SunPower Corporation Labor Coverage • SunPower Corporation Performance Guarantees (production guarantees) • SunPower Corporation Complete Confidence Warranty • SunPower Equinox System Warranty (the combined system warranty)

How to File Warranty Claims:

For panel issues, contact Maxeon Solar Technologies directly through their website (maxeon.com) or authorized service providers. For inverter or other equipment issues, contact the equipment manufacturer directly. Keep all documentation including purchase receipts, installation records, and system specifications.

Finding Service Providers:

• Local Solar Installers: Most local solar installation companies can service SunPower systems • Equipment Manufacturers: Contact your inverter manufacturer for authorized service providers • Solar Service Specialists: Companies specializing in solar maintenance and repair • Former SunPower Dealers: Many former SunPower dealer partners continue to service existing systems • Complete Solar: The new entity may provide limited service (contact: 877-299-4943)

What to Expect:

You will likely need to pay out-of-pocket for labor and service calls, even if equipment is under manufacturer warranty. Get quotes from multiple service providers. Expect to pay standard service rates ($100-200 for diagnostics, $150-300 per hour for repairs).

If you have a solar lease or Power Purchase Agreement (PPA) with SunPower:

Current Status:

• Most lease/PPA agreements were transferred to third-party financing companies or Complete Solar • You must continue making payments as per your contract • Maintenance obligations may have transferred to the new entity • Check your contract documents for assignment clauses

Your Rights:

• System must be maintained according to your agreement • If system is not producing as guaranteed, you may have grounds to renegotiate • Document all system issues and maintenance requests • Consult a consumer protection attorney if the new entity is not fulfilling obligations • Contact your state attorney general office if you believe your rights are being violated

In September 2024, Complete Solar acquired SunPower Corporation assets for $45 million. In April 2025, Complete Solar rebranded their operations as "SunPower," creating significant confusion for customers.

Key Differences:

Original SunPower Corporation (Bankrupt):

• Filed for bankruptcy August 2024 • No longer operates • Shut down all customer support • Warranties and guarantees void • Over 500,000 customers affected

New "SunPower" (Complete Solar):

• Acquired assets September 2024 • Operates under SunPower brand name • Limited support for pre-bankruptcy customers • New installations and service offerings • Different company, different obligations • Contact: (877) 299-4943
