Research confirms ASM functions primarily as a solar installer in New South Wales rather than a panel manufacturer in any meaningful sense - the aggregated dataset lists zero panels in its portfolio and carries no production capacity or efficiency figures. Corab, by contrast, is a Polish company founded in 1993 with over 300 employees and a declared production capacity of 2.5 GW. Though Corab does not appear on major Tier 1 bankability lists such as those published by BloombergNEF, it has a significantly stronger institutional footprint: it is recognised as the largest distributor of Risen Energy modules in Poland and one of the largest in Europe, and has entered a partnership to develop 1 GW of agrivoltaic projects domestically. On portfolio character, the contrast is stark and simple: ASM has no documented panel lineup at all, making any product-level comparison impossible. Corab's four-model range centres on monofacial monocrystalline panels averaging 395 Wp and peaking at 410 Wp, with an average efficiency of 20.52% and a top module efficiency of 21%. The average temperature coefficient of -0.34%/C is competitive for mid-tier monocrystalline products, and the standard 25-year warranty aligns with current market norms. No bifacial models appear in the portfolio. This lineup fits small-to-medium commercial rooftops and residential installations in European markets, where Corab has an established distribution network. For any buyer evaluating these two as solar panel suppliers in 2025, the choice is not a close one. Corab offers a real, documented product range with reasonable efficiency figures and warranty terms, while ASM presents no panel portfolio whatsoever. Unless ASM's role is strictly as a local Australian installer - in which case it is not comparable as a manufacturer - Corab is the only viable option of the two for procurement decisions. \---LINKS--- \- https://www.solarfeeds.com/biz/corab-sp-z-o-o/ \| Corab company overview - production capacity and tier status \| review \- https://renewablesnow.com/news/corab-kelfield-plan-to-develop-1-gw-of-agrivoltaics-in-poland-827098/ \| Corab and Kelfield plan 1 GW agrivoltaics development in Poland \| article \- https://www.enfsolar.com/corab \| Corab S.A. manufacturer profile - ENF Solar directory \| review \- https://www.energysage.com/solar/bankability-what-is-it-how-do-you-assess-it/ \| What is solar panel bankability and how is it assessed - EnergySage \| article Sources: \- \[Corab company overview - SolarFeeds\](https://www.solarfeeds.com/biz/corab-sp-z-o-o/) \- \[Corab and Kelfield plan 1 GW agrivoltaics in Poland - Renewables Now\](https://renewablesnow.com/news/corab-kelfield-plan-to-develop-1-gw-of-agrivoltaics-in-poland-827098/) \- \[Corab S.A. manufacturer profile - ENF Solar\](https://www.enfsolar.com/corab) \- \[What is bankability - EnergySage\](https://www.energysage.com/solar/bankability-what-is-it-how-do-you-assess-it/) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
