ASM vs Panasonic - solar panel manufacturer comparison
Panasonic has the broader catalog (25 vs 1 models). Panasonic leads on peak efficiency at 22.20%. Panasonic leans bifacial (16% of lineup).
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
ASM does not appear in any major solar industry database, BloombergNEF Tier 1 list, or trade-press coverage as a recognized panel manufacturer. Web searches consistently return either ASM Solar - an Australian residential installation and service company - or ASM, a Dutch semiconductor equipment firm unrelated to photovoltaics. Without verifiable manufacturer-level data on ASM, only a qualitative note is possible on that side: if ASM is intended as a regional installer or small-scale brand, it is not yet operating at a scale that attracts independent analyst coverage, and no bankability or production-capacity figures can be cited in good conscience.
Panasonic, by contrast, has a well-documented solar history. Founded in Japan in 1918 as Matsushita Electric, it pioneered heterojunction technology - branded HIT, for heterojunction with intrinsic thin-layer - with the world's first commercially available HJT panels in 1997. Over the following decades those modules earned a premium reputation for high efficiency, excellent temperature coefficients, and long-term power retention. Its EverVolt residential line, however, was not self-manufactured: after Panasonic ceased in-house module production in 2021, EverVolt panels were made under contract by REC Group. On April 28, 2025, Panasonic North America announced a full exit from solar and battery storage, ending the EverVolt line entirely. Existing 25-year AllGuard warranties remain honored by the parent company.
For a buyer in 2025, Panasonic solar is effectively a legacy product - no new panels are being produced or sold, though existing installed systems with active warranties remain supported. Without a credible manufacturer profile for ASM, a head-to-head verdict is not possible. Buyers seeking high-efficiency HJT modules in the Panasonic tradition should look instead at REC Group (which made EverVolt panels) or other active HJT specialists.
