For much of the 2010s it was among the most bankable residential panel brands, and it held Tier 1 recognition during peak production years. However, in April 2025 Panasonic announced the discontinuation of its solar and battery storage business lines, following a sharp decline in market share - from roughly 35% of U.S. residential installations in 2020 to around 6% by 2024, per EnergySage. The company had already stopped manufacturing its own cells in 2022, moving to third-party production. AEET Energy Group GmbH is a much smaller, regionally focused company headquartered in Bad Gandersheim, Germany, operating primarily as a photovoltaic wholesale distributor and full-service installer rather than a mass-market manufacturer. No independent Tier 1 or BloombergNEF bankability status was found for AEET in available sources. In terms of institutional footprint, Panasonic historically held the stronger position, though that standing is now moot given its market exit. Panasonic's EverVolt panels used heterojunction (HJT) cell technology, which delivered efficiency ratings above 22% and industry-leading temperature coefficients - making them a well-regarded choice for premium residential rooftop installations with limited roof area. AEET Energy Group offers monocrystalline, polycrystalline, and thin-film modules through its wholesale channel, targeting residential and small commercial projects mainly in the European market. No specific cell technology generation (TOPCon, HJT, PERC) was confirmed in available third-party sources for AEET's current catalog. For any buyer evaluating these two brands in 2025, the choice is effectively settled by circumstance: Panasonic panels are no longer actively sold as new products, and while existing warranties are honored by the company, no new inventory pipeline exists. AEET Energy Group serves a niche European wholesale role and is not a comparable global alternative. Buyers seeking an HJT-tier residential panel would be better served looking at currently active manufacturers such as REC or Maxeon, and those seeking a European wholesale partner should vet AEET directly against regional competitors with documented Tier 1 standing. \---LINKS--- \- https://pv-magazine-usa.com/2025/04/30/panasonic-exits-solar-and-battery-storage-ending-decades-long-journey/ \| Panasonic exits solar and battery storage, ending decades-long journey \| article \- https://www.energysage.com/news/panasonic-exits-solar-and-energy-storage-market/ \| Panasonic is closing its solar and battery storage business \| article \- https://cleantechnica.com/2025/04/30/panasonic-steps-away-from-solar-storage-ends-evervolt-line/ \| Panasonic Steps Away From Solar and Storage, Ends EverVolt Line \| article \- https://www.solarreviews.com/blog/are-panasonic-solar-panels-the-best-modules-to-install-on-your-home \| 2025 Panasonic Solar Panels - Expert Review \| review \- https://www.enfsolar.com/aeet \| AEET Energy Group GmbH - Solar Panels - Germany \| article Sources: \- \[Panasonic exits solar and battery storage - pv magazine USA\](https://pv-magazine-usa.com/2025/04/30/panasonic-exits-solar-and-battery-storage-ending-decades-long-journey/) \- \[Panasonic is closing its solar and battery storage business - EnergySage\](https://www.energysage.com/news/panasonic-exits-solar-and-energy-storage-market/) \- \[Panasonic Steps Away From Solar and Storage - CleanTechnica\](https://cleantechnica.com/2025/04/30/panasonic-steps-away-from-solar-storage-ends-evervolt-line/) \- \[2025 Panasonic Solar Panels Expert Review - SolarReviews\](https://www.solarreviews.com/blog/are-panasonic-solar-panels-the-best-modules-to-install-on-your-home) \- \[AEET Energy Group GmbH - ENF Solar\](https://www.enfsolar.com/aeet) Written by claude-sonnet from the figures above. ## Other comparisons - [Panasonic vs A.B.
