Sanyo Solar Panel Delamination Settlement

Sanyo Solar Panel Delamination Settlement

Replacement panels or a prorated refund, per panel — no cap

Proof Required?
The deadline on this page is not one date. It is the earlier of twenty years from the day you bought the panels or 31 December 2029, and the administrator is blunt about what that means: if that period has already expired, you are not eligible to submit a claim. Work yours out before anything else. Panels bought in 2004 ran out in 2024. Panels bought in 2008 have until 2028. Only panels bought from the start of 2010 onward get the full run to December 2029. The case is about delamination. Sanyo-brand panels in three model series are alleged to come apart in layers over time, which can cost you output. Sanyo Energy and Sanyo North America no longer exist, having merged into Panasonic Corporation of North America in 2015, so Panasonic is the company on the other side of this, and every reference to Sanyo in the old limited warranty is now read as Panasonic. Check your model number before you read further. The settlement covers the HIP-xxxBA2, BA3 and BA5 series and nothing else. The HIP-xxxDA3 and HIP-xxxBA19 series are expressly outside it. What you get is either replacement panels or a prorated cash refund, and you do not choose which. An independent administrator decides whether your panels show qualifying damage, and if they do, the defendants pick the remedy. One figure to ignore: this page used to promise up to $700. That number is the purchase price the court assumed for a single panel when it estimated the settlement's value. In the same example the refund worked out at $350 a panel. It is not a cap, and on a large array the total can run well past it.

Who Is Eligible?

You may be eligible to file a claim if you:

  • There are two subclasses. The first is everyone in the United States who purchased and installed Sanyo-brand solar panels from the HIP-xxxBA2, BA3 or BA5 model series for residential use. The second is anyone who later bought a home, building or ground-mounted system with those panels already on it.
  • That second subclass is easy to miss. You did not have to buy the panels yourself. Buying a house with them on the roof puts you in.
  • Residential use is the boundary. A commercial installation of the same panels is not what this covers.
  • Model series decides everything, and two are named as outside it. HIP-xxxDA3 and HIP-xxxBA19 panels are expressly not in the settlement. Their owners are pointed to the ordinary limited warranty process instead, which FAQ 27 on the administrator's site explains.
  • The damage has to be delamination that meets visual criteria. The administrator publishes two reference documents, one showing panels with qualifying damage and one showing panels without, and reading both before you photograph anything will tell you quickly whether you have a claim.
  • This route is now the only route for delamination. The settlement replaced whatever warranty procedure previously applied to these models for delamination claims, so going to Panasonic directly about it will send you back here.
  • Excluded are anyone who opted out, the defendants and entities they control, their legal representatives, heirs and successors, settlement class counsel and their immediate families, and any judge assigned to the case along with their immediate families.
  • Nothing here touches fire. The release expressly leaves out claims for personal injury and property damage related to fires, and claims against anyone other than the released parties.

How Much Can You Get?

Two remedies exist and the claimant does not pick between them. An independent claim administrator decides whether your panels show qualifying damage, and if they do, the defendants choose whether you get replacement panels or a prorated cash refund. The refund is prorated by how much useful life the panel had left, which is the whole calculation, and it means a panel bought in 2006 is worth far less than the same panel bought in 2012.

The $700 on this page was never a payout. It was the purchase price the court assumed for one panel when estimating what the settlement was worth, and in that same illustration a panel with half its useful life left produced a refund of $350.

Per panel is the unit, which cuts both ways. The court's estimate assumed roughly 136,066 Sanyo settlement panels in total and a 15% damage rate. A household with twenty qualifying panels is in a very different position from one with two, and on a large array the total can run well past $700.

No fund, no cap.

The court described this as a claims-made settlement with no common fund, so your payment does not shrink because other people filed. That is the opposite of how most settlements on this site work, and it is the single most favorable thing about this one. Class counsel were separately awarded $1,672,265.03 in fees and $72,734.97 in costs, measured against a lodestar of $2,174,969.

Timing runs against you twice. Every month reduces the remaining useful life the refund is based on, and it moves you closer to the twenty-year cutoff.

How to File Your Claim

File with the administrator:

  • Work out your own deadline first. Twenty years from your original purchase date, or 31 December 2029, whichever comes sooner. The administrator states plainly that if the period has expired you are not eligible, so this is the step that decides whether the rest is worth doing.
  • Find the model number on the panel label. You need HIP-xxxBA2, BA3 or BA5. DA3 and BA19 are different series and are not in this settlement.
  • Look at the two example documents before you photograph anything. The administrator publishes one file showing panels with qualifying damage and another showing panels without it, and comparing your own panels against both will save you a rejected claim.
  • Then assemble three things: the completed claim form, photographs, and proof that you own the panels. The claim form is downloadable from sanyosolarclaims.com and its instructions set out exactly which photographs and which ownership documents are wanted.
  • Send it by email or by post. Email goes to sanyosolarclaims@4class.com. Post goes to Ziccarello v Sanyo Energy (U.S.A.) Corp. Claims, Class Litigation Administration Support Services, PO Box 1272, Lancaster, California 93584.
  • If your panels are DA3 or BA19, or your problem is power output rather than delamination, you are in the ordinary warranty system instead. That now runs through Panasonic, at its solar warranty page or by email to PanasonicHIT@us.panasonic.com, because the Sanyo companies were absorbed into Panasonic in 2015 and no longer process warranty claims.
  • The settlement hotline is 1-844-702-2787 and it is free to call.

Frequently Asked Questions

What is the deadline to file a claim for the Sanyo Solar Panel Delamination Settlement?

The current deadline to file a claim is Dec 31, 2029. Claims sent by mail must be postmarked by this date, so allow about a week for delivery if you are not filing online.

Do I need documentation for the Sanyo Solar Panel Delamination Settlement?

Yes — this settlement requires supporting documentation, and what counts is set out on the official claim form rather than being the same in every case: a consumer case may ask for receipts or order confirmations, while a financial or data-breach case usually turns on account records or the notice the administrator sent you. You also do not need a Claimant ID or PIN to file.

How do I file a claim for the Sanyo Solar Panel Delamination Settlement?

File directly with the settlement administrator, using the official claim form linked on this page. Class Action Buddy does not support this settlement in the app, so the administrator’s own claim process is the route. You do not need a Claimant ID or PIN to file.

Do I have until December 2029 to file?

Not necessarily. The deadline is the earlier of twenty years from your original purchase date or 31 December 2029. Panels bought in 2004 ran out in 2024; panels bought in 2008 run out in 2028. Only panels bought from 2010 onward get the full window, and the administrator says that if your period has expired you are not eligible.

Which panel models are covered?

HIP-xxxBA2, HIP-xxxBA3 and HIP-xxxBA5, installed for residential use. The model number is on the panel label.

I have HIP-xxxDA3 panels. Am I in?

No. The HIP-xxxDA3 and HIP-xxxBA19 series are expressly outside this settlement. Owners of those panels use the ordinary limited warranty process through Panasonic instead.

I bought a house that already had the panels on it.

Yes. Buying a house, building or ground-mounted system with qualifying panels already installed puts you in the second subclass. You did not have to buy the panels yourself.

What counts as the defect?

Delamination, meaning the panel coming apart in layers over time, which can reduce output. It has to meet visual criteria, and the administrator publishes example photographs of panels that do and do not qualify.

Can I choose cash instead of replacement panels?

You do not choose. An independent administrator decides whether the damage qualifies, and then the defendants decide whether you receive replacement panels or a prorated cash refund.

Is the payout really up to $700?

It was never a payout figure. $700 is the purchase price the court assumed for one panel when valuing the settlement, and in that same example the refund came to $350 per panel. There is no cap, and the unit is the panel, so a large array can be worth considerably more.

What do I have to send in?

A completed claim form, photographs, and proof that you own the panels, sent to sanyosolarclaims@4class.com or posted to the administrator in Lancaster, California.

Why does Panasonic keep coming up?

Sanyo Energy and Sanyo North America merged into Panasonic Corporation of North America in 2015 and no longer exist to process warranty claims. The court ordered that every reference to Sanyo in the limited warranty is now read as a reference to Panasonic.

What case is this?

Ziccarello v. Sanyo Energy (U.S.A.) Corporation, No. 2:19-cv-16623, in the United States District Court for the District of New Jersey, before Magistrate Judge Cathy L. Waldor. Final approval was granted on 8 July 2021 and the settlement took effect on 10 August 2021.
