Panasonic Solar Review (Philippines): Great Panels You Can No Longer Buy New
Published specifications for the EverVolt (HJT), discontinued 2025. A brand ships several series, so these figures describe this model and not every product the manufacturer sells.
- Status
- DiscontinuedPanasonic announced the end of its entire solar and battery line in a letter to installation partners dated 28 April 2025, describing it as a strategic decision rather than a product-quality one.
- Rated power
- not publishedHistorical line. No current SKU to quote.
- Cell technology
- Heterojunction (HJT)
- Module efficiency
- Roughly 19-21%Historical figures for the EverVolt line.
- Annual degradation
- As low as roughly 0.25% per yearAgainst a typical 0.5% industry figure. Genuinely strong, and panels already on a roof keep performing the way they always have.
- Product warranty
- not publishedPanasonic has stated it will honour existing warranties, including systems not yet fully installed at the announcement. How that plays out for Philippine owners specifically is unverified.
- Performance warranty
- not publishedSame as above. If you own these panels here, get the current service process in writing from Panasonic Philippines or your original installer.
- Philippine channel
- None for new purchasePanasonic Philippines Electric Works and past listings named a local distributor, but that reflects the pre-2025 lineup. With global manufacturing and sales discontinued there is no verifiable path to buying new.

What it does well
- HJT cells with degradation as low as roughly 0.25% per year, half the typical industry figure, so existing installations hold output unusually well.
- Panasonic has stated it will continue honouring existing warranties, including systems that were not yet fully installed when the exit was announced.
- Panels already on a roof keep performing exactly as before, since the corporate exit does not retroactively change installed hardware.
Where it falls short
- You cannot buy these new. Manufacturing and sales are discontinued globally, so this is not a brand you can spec into a system today.
- How the global warranty commitment is actually serviced for Philippine owners is unverified, so it needs confirming in writing rather than assuming the global policy applies unchanged.
- Marketplace listings for Panasonic panels may still be up, and any of them needs real scepticism about whether the stock is genuine before money changes hands.

Dashes are figures the manufacturer does not publish, not zeros. Where two products differ on a spec, which one matters depends on your roof and your usage — a higher efficiency panel earns its premium on a small roof and rarely on a large one.
Panasonic made excellent, low-degradation panels — but the company has fully exited the solar and battery storage business, so this isn’t a brand you can actually buy new panels from anymore. This review is mainly useful if you already own Panasonic panels and are asking about warranty support.
What happened
Panasonic stopped manufacturing its own solar cells and panels in-house back in 2021-2022, closing factories in Malaysia and Japan and shifting to outsourced manufacturing while continuing to sell Panasonic-branded modules (marketed as EverVolt) through subcontractors. That was already a step back from full in-house production, but the bigger change came later: in a letter to installation partners dated April 28, 2025, Panasonic announced it was discontinuing its entire solar and battery storage line — panels, batteries, and inverters — describing it as a strategic decision rather than a reflection of product quality. Panasonic’s own reported share of new solar installations had fallen from roughly 35% in 2020 to about 6% by 2024 before the exit. It joined LG (solar division closed in 2022) and SunPower/Maxeon (residential exit, and now under judicial management — see our SunPower/Maxeon review) as a third major brand name to step away from residential solar in a short span.
Lineup and specs (historical)
Before the exit, Panasonic’s EverVolt line used HJT (heterojunction) cell technology, generally in the 19-21% efficiency range, known in the industry for holding up well over time — degradation as low as roughly 0.25% per year, better than the typical 0.5% industry figure. That’s genuinely strong hardware, and panels already on a roof keep performing the way they always have; the exit doesn’t retroactively change what’s installed.
Warranty
Panasonic has stated it will continue honoring existing warranties, including for systems that weren’t yet fully installed at the time of the announcement, and has pointed customers to third-party warranty-support channels for guidance. If you already have Panasonic panels, that’s the reassuring part. What’s unverified is exactly how that support plays out for owners specifically in the Philippines rather than in Panasonic’s larger markets like the US — if you own Panasonic panels here, contact Panasonic Philippines or your original installer directly and get the current warranty-service process in writing rather than assuming the global policy applies unchanged locally.
Local availability
Panasonic Philippines’ Electric Works division and past listings named a local distributor for solar panels, but that channel reflects the pre-2025 lineup. With global manufacturing and sales discontinued, there’s no verifiable path to buying new Panasonic solar panels in the Philippines today — old product listings and marketplace pages may still be up, but treat any “Panasonic solar panel for sale” listing you find online with real skepticism about whether it’s genuine remaining stock, and confirm directly with the seller before paying anything.
Price
Not applicable for a new purchase — Panasonic isn’t a panel you can currently spec into a new system. Older market data put installed Panasonic panels at the high end of the price range (previously cited around ₱42,000-56,000 per unit for 400-500W panels), consistent with its premium positioning while it was still being sold, but that figure is now historical rather than a current buying reference.
Where it falls short
The product itself was never the problem — availability is. A brand you can’t currently order new panels from isn’t a realistic option if you’re planning a system today, no matter how good the hardware was.
Who it’s best for
Existing Panasonic solar owners looking for warranty-support guidance, not new buyers. If you’re shopping for a new system, look at brands with an active, verifiable Philippine channel instead — see our best solar panel brands guide and tier-1 vs tier-2 panels guide for how to evaluate what’s actually available to you, and our panel brand roundup for currently active alternatives like Canadian Solar or Trina Solar.
