Panasonic panels — beware post-2022 rebrands
By Fotovol Team·Updated 26 April 2026
Short answer
Japanese manufacturer that invented HIT (heterojunction) technology in 1997. Panasonic shut down its own panel production in 2021 and now resells OEM-built panels under the brand. Remaining stock on the Romanian market is limited — be careful with warranty claims on "Panasonic" panels sold post-2022, many are rebrands. The actual quality now traces to a Japanese partner, not the badge on the panel.
When to pick it
Honestly? Rarely. In 2026 Panasonic is an option only for:
- Buyers fixated on a Japanese brand who explicitly accept that panels are rebadged OEM and don't ask for cell traceability.
- Pre-2022 leftover stock with the original Panasonic warranty still valid — real lots, not rebrands. Ask for the manufacturing date on the sticker.
Otherwise, the money is better spent on REC, Q-Cells or Maxeon if you want non-Chinese premium.
Watch-outs
- "Panasonic" panels manufactured 2023+ — 99% are rebadged OEM. The warranty runs through the Japanese importer, not Panasonic Energy.
- Distributors who can't show the supply chain — ask who they buy from, who the actual OEM is (often Solar Frontier or smaller Japanese makers).
- Prices equal to Maxeon or REC at the same wattage — no technical justification. You're paying for the logo, not the tech.
