If you have a system from the "old" SunPower, the company you deal with now depends on how you paid for it and when it was installed. Here's how to tell.

The short answer

  • SunPower Corporation filed Chapter 11 on August 5, 2024 in the U.S. Bankruptcy Court for the District of Delaware (Case No. 24-11649) [1][2].
  • Today's "SunPower" is a different company. SunPower Inc., formerly Complete Solaria, bought the SunPower brand and some divisions in a deal that closed on September 30, 2024. It did not take on customer leases, PPAs, or systems installed before that date [2].
  • Lease and PPA customers: contact your financier or SunStrong Management at (833) 514-1858 [2]. SunStrong says it took on management of more than 110,000 former SunPower customers and assets in Q3 2024 [3].
  • Cash and loan customers: SunPower Inc. says to contact your lender [2].
  • Monitoring: the mySunPower app has been replaced by the SunStrong Connect app, which is only for former SunPower customers [4].

What the 2024 bankruptcy means, by contract type

Find your situation below. "Legacy" means a system installed by SunPower Corporation on or before September 30, 2024.

You have… Who handles it now What SunPower Inc. / SunStrong say
Lease or PPA Your financier or SunStrong Management [2] Call SunStrong at (833) 514-1858 [2]. SunStrong lists SunPower among the originators it bills for, with a single "Lease, Loan and PPA" payment portal [5].
Loan Your lender [2] SunPower Inc. didn't take over these accounts. SunStrong's account page also lists a SunPower "Lease, Loan and PPA" portal [5], so check your latest statement for your servicer's name.
Cash purchase No lender or servicer involved Use the manufacturers' warranties (see below) [6]. SunStrong says it doesn't maintain systems owned outright [7].
Installed by Blue Raven Solar or Complete Solar (any date), or by SunPower Inc. after Sept. 30, 2024 SunPower Inc. SunPower Inc. says the warranties in those installation agreements remain valid [6].

If SunPower Corporation owes you money, SunPower Inc. points to the bankruptcy administrator's site, dm.epiq11.com/case/sunpower, and to SunPowerinfo@epiqglobal.com [2].

SunPower Inc. (Complete Solaria) vs. SunStrong

  • SunPower Inc. (formerly Complete Solaria, Inc.) bought "certain assets." These included the Blue Raven Solar, New Homes and Non-Installing Dealer divisions, plus the "SunPower" brand and trademarks [2]. Its support line is (877) 299-4943 [2].
  • SunStrong Management manages contracts and customer accounts that SunPower Inc. didn't buy, including legacy leases and PPAs [2][3]. Connecticut's Attorney General describes SunStrong as managing "loans, leases and power purchase agreements" previously held by Sunnova and SunPower [8].
  • Regulator scrutiny: in a civil investigative demand sent February 27, 2026, Connecticut's AG asked SunStrong for records on "the transfer of systems from the bankrupt Sunnova and SunPower to SunStrong," among other items [8]. An investigation is not a finding of wrongdoing.

Warranties after the bankruptcy

  • Systems installed on or before September 30, 2024: SunPower Inc. says it didn't take on any interest in these systems. It directs warranty questions to its warranty page [2][6]. That page refers cash and loan customers to their lender, and lease and PPA customers to their financier or SunStrong [6].
  • Manufacturer warranties: SunPower Inc.'s warranty page lists manufacturer contacts for components. For example, it lists spwrquery@enphaseenergy.com for Enphase microinverters [6]. Check your Home Improvement Contract or Installation Agreement for the exact manufacturers of your components [6].
  • Enphase support: Enphase runs a support page for legacy SunPower systems that use Enphase equipment. Cash and loan customers can call Enphase at (510) 945-6752. Lease and PPA customers should use the support number on their billing statement [9].
  • Lease and PPA production guarantees and repairs: ask SunStrong in writing which terms of your original contract it will honor.

Monitoring: mySunPower → SunStrong Connect

From SunStrong's Help Center [4]: - The SunStrong Connect app, "formerly mySunPower," monitors solar production and home energy use. It's "currently only accessible by former SunPower customers." - The web portal is no longer supported. Use the mobile app. - Free features: - System health alerts - Live production monitoring - SunVault battery management - WiFi management and firmware updates - Premium features ($9.99/month or $99.99/year): - Historical data - Panel-level monitoring (systems with micro-converters only) - Production and consumption analytics - Monthly reports - Lease customers get premium features at no cost as part of their lease service. - Don't send money in advance. SunStrong says you'll be prompted in the app when subscribing becomes available. - Cellular connections: "free cellular connectivity is no longer available." SunStrong recommends connecting by WiFi or Ethernet. It warns that a system relying only on cellular without an active subscription risks "permanent hardware damage which may impact energy production."

Separately, SunPower Inc. says many legacy systems use Enphase microinverters with a SunPower-branded combiner box. It says Enphase has offered a paid upgrade kit that swaps in Enphase-branded equipment for monitoring and support [2]. Contact Enphase at (510) 945-6752 for current options [9].

Selling a home with a legacy SunPower system

  • Lease or PPA:
  • Tell SunStrong early. Its homeowners page has a "Sell My Home" quick action ("Let us know as soon as possible if you are selling your home with solar") [10].
  • On SunStrong's inquiry form, SunPower customers are sent to a separate request portal for "Refinance, Lease Changes, or Home Sale" requests [7]. That portal lists a "Want to Payoff your System?" option [11].
  • The form asks for the buyer's contact details, the title company contact and the estimated closing date [7].
  • Loan: contact the lender or servicer named on your statement for a payoff letter or its transfer rules. SunPower Inc. didn't take on these accounts [2][5].
  • Cash: gather your warranty documents and the manufacturers' contacts for the buyer [6].
  • Title and the buyer's lender:
  • For leased or PPA panels, Fannie Mae treats a "precautionary" UCC filing covering only the equipment as "a minor impediment to title."
  • The buyer's lender must count the lease payment in the debt-to-income ratio unless the agreement meets specific fixed-energy and production-guarantee conditions [12].
  • For loans paid off at closing, the model UCC § 9-513 requires a termination of the secured party's filing within one month of payoff, or within 20 days of your authenticated demand, whichever comes first. State versions vary [13].
  • Virtual power plant (VPP): if you're enrolled in SunStrong's VPP program, SunStrong says selling or refinancing may affect your enrollment and future rewards [4].
