For many years Panasonic held BloombergNEF Tier 1 status and commanded a significant share of the North American residential market - roughly 35% in 2020. However, the company stopped manufacturing solar panels in-house in 2021, outsourcing production of its EverVolt line to REC Group, and ultimately exited the solar and battery storage business entirely on April 28, 2025, citing uncompetitive pricing from Chinese rivals. No new Panasonic or EverVolt panels are being produced; the brand's institutional footprint in solar is now largely historical. AIKO, by contrast, is a Chinese manufacturer that earned BloombergNEF Tier 1 bankability recognition in Q3 2024 and has been scaling aggressively, with reported annual production capacity around 20 GW in early 2025 and projections above 35 GW by mid-2026, placing it among the top ten Tier 1 suppliers by volume. Panasonic's EverVolt panels were built on N-type HJT cells and were marketed squarely at the premium residential rooftop segment, offering efficiencies up to around 22.2% and a strong 25-year product and performance warranty. AIKO differentiates itself with All Back Contact (ABC) N-type cell architecture, which moves all electrical contacts to the rear of the cell to maximize light-capturing surface area. AIKO announced a world record 24.4% module efficiency for mass-produced commercial panels in June 2025, and its Gen 3 ABC range carries a 30-year performance warranty with a low annual degradation rate of 0.35% after the first year. For any buyer evaluating the two brands in 2025 or beyond, the choice is effectively settled: Panasonic no longer manufactures solar panels and cannot be specified for new installations. AIKO is an active, Tier 1-rated, high-performance alternative that now occupies much of the premium residential and commercial space that Panasonic once served. \---LINKS--- \- https://www.pv-magazine.com/2025/05/01/panasonic-exits-solar-and-battery-storage-ending-decades-long-journe/ \| Panasonic exits solar and battery storage - pv magazine \| 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://aikosolar.com/en/aiko-achieves-prestigious-tier1-status/ \| AIKO Achieves BloombergNEF Tier 1 Status \| article \- https://www.solarreviews.com/blog/are-panasonic-solar-panels-the-best-modules-to-install-on-your-home \| 2025 Panasonic Solar Panels Expert Review - SolarReviews \| review \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar Panels Review - SolarQuotes \| review Sources: \- \[Panasonic exits solar and battery storage - pv magazine\](https://www.pv-magazine.com/2025/05/01/panasonic-exits-solar-and-battery-storage-ending-decades-long-journe/) \- \[Panasonic Steps Away From Solar and Storage - CleanTechnica\](https://cleantechnica.com/2025/04/30/panasonic-steps-away-from-solar-storage-ends-evervolt-line/) \- \[AIKO Achieves BloombergNEF Tier 1 Status\](https://aikosolar.com/en/aiko-achieves-prestigious-tier1-status/) \- \[2025 Panasonic Solar Panels Expert Review - SolarReviews\](https://www.solarreviews.com/blog/are-panasonic-solar-panels-the-best-modules-to-install-on-your-home) \- \[Aiko Solar Panels Review - SolarQuotes\](https://www.solarquotes.com.au/panels/aiko-solar-review.html) Written by claude-sonnet from the figures above. ## Other comparisons - [Panasonic vs A.B.
