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 is a micro-scale Australian company founded in 2009 with a reported headcount of just 1-10 employees and no Tier 1 bankability designation. Its public panel portfolio contains no documented products, meaning no power ratings, efficiency figures, or warranty terms are available for independent scrutiny. IBC Solar, by contrast, is a long-established German firm founded in 1982 with roughly 500 employees and more than 11 GW of photovoltaic systems realized worldwide. It carries a listing on the NewConnect exchange and has a transparent, catalogued product range. On institutional footprint alone, IBC Solar is in an entirely different league.
IBC Solar's 33-panel portfolio averages 458.8 Wp per module, with a ceiling of 720 Wp, and average panel efficiency of 22.1% rising to a peak of 23.18%. The dominant cell architecture is TOPCon, accounting for about 39% of the lineup, with the remainder spanning complementary n-type variants. Roughly 45% of the portfolio is bifacial, a strong share that reflects a deliberate push toward both commercial rooftop and ground-mount applications. The average temperature coefficient sits at -0.31%/degree C, which is competitive for the technology tier, and the mean warranty term is 30 years - a generous figure that signals confidence in long-term yield stability. That combination of high wattage, respectable efficiency, and a bifacial-heavy catalog positions IBC Solar squarely for premium residential, commercial rooftop, and mid-scale ground-mount buyers who want bankable performance data behind their purchase.
For any typical buyer evaluating these two manufacturers in 2025, the comparison is effectively one-sided. IBC Solar offers a documented, technically competitive product range backed by four decades of operational history, a traceable capacity record of 11+ GW, and a warranty posture suited to project finance. ASM, with no public panel specifications and a workforce of under ten people, cannot be meaningfully evaluated on technical or financial-risk grounds. Unless a buyer has a specific regional or supply-chain reason to work with ASM directly, IBC Solar is the clear default choice on every measurable criterion.
