Panasonic Solar in 2026: Discontinued, But Warranties Still Honored
Panasonic exited the residential solar panel business in 2025 and is no longer manufacturing or selling new EverVolt panels. For several years before that, Panasonic’s panels were already being manufactured under an OEM arrangement by REC Group rather than by Panasonic itself, meaning the underlying cell technology and factory were effectively the same as REC’s own Alpha line. If you’re being quoted «Panasonic panels» for a new installation in 2026, it’s worth asking your installer to confirm exactly what’s being installed, since new-production EverVolt panels are no longer available from the manufacturer.
Existing Panasonic warranties remain valid and are still being honored by Panasonic, a large, financially stable company with over a century of operating history. If a warranty claim requires a physical panel replacement, homeowners should expect an equivalent third-party panel or a cash-value settlement rather than an identical original EverVolt unit, since the specific model is no longer produced — a standard practice when a manufacturer exits a product line.
Panel Technology and Historical Specs
Panasonic’s EverVolt panels used heterojunction (HIT/HJT) cell technology, combining crystalline and amorphous silicon layers, which delivered efficiency ratings generally in the 21-22% range and a strong temperature coefficient. Depending on the specific series (EverVolt, EverVolt H, EverVolt K/PK/HK Black), degradation guarantees ranged from roughly 86% to 92% of original output retained at year 25, with the higher-tier H Series models performing at the stronger end of that range.
Warranty: What Happens Now
Panasonic’s EverVolt panels historically carried a 25-year TripleGuard or AllGuard warranty covering product, performance, and (when installed by an authorized installer) labor. Panasonic continues to honor these warranties for existing customers as of 2026. Panasonic’s Daybreak monitoring platform for solar systems stopped enrolling new systems after the end of 2025, so owners of an existing Panasonic system without independent monitoring already set up should ask their installer about switching to Enphase Enlighten or another third-party monitoring platform.
What to Buy Instead
Because Panasonic panels were OEM-manufactured by REC Group using the same HJT cell technology, REC’s current Alpha Pure line is the closest like-for-like successor available for new installations, generally at a higher wattage than the last EverVolt models. Homeowners specifically drawn to Panasonic’s brand reputation for reliability and manufacturer longevity may also want to consider Qcells or Maxeon, both of which carry strong warranty backing from financially stable parent companies.
Panasonic EverVolt Home Battery: Still Active
Unlike its panel line, Panasonic’s EverVolt home battery storage system remains an active product as of 2026, sold and installed through Panasonic’s certified installer network, with configuration-based pricing and a 10-year warranty. It’s worth noting this is a separate product line from the discontinued panels — a homeowner can still buy an EverVolt battery in 2026 even though EverVolt panels are no longer manufactured.
