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 industry databases consulted for this comparison, including BloombergNEF Tier 1 lists, pv-tech.org, pv-magazine.com, or ENF Solar's manufacturer directory. The name overlaps with ASM International, a Dutch semiconductor equipment company, and ASM Pacific Technology, a Hong Kong assembly-equipment firm - neither of which manufactures solar panels. Without verifiable data on ASM's headquarters, founding date, production capacity, product families, or bankability status, no reliable factual comparison can be made for this brand. Buyers and project developers are strongly advised to request manufacturer documentation and independent certification directly from any distributor claiming to supply ASM solar modules before committing to a purchase.
JA Solar, by contrast, is one of the most thoroughly documented solar manufacturers in the world. Founded in 2005 and headquartered in Beijing, it is listed on the Shenzhen Stock Exchange and has been a consistent presence on BloombergNEF's Tier 1 bankability list - a designation confirming that multiple independent banks have financed projects using its modules on a non-recourse basis. Its nameplate manufacturing capacity exceeds 100 GW per year, and in the first half of 2025 the company shipped approximately 34 GW of modules, with n-type products representing roughly 96% of output. Manufacturing facilities outside China further reduce supply-chain and tariff exposure for international buyers.
JA Solar's product range spans residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount applications. Its Deep Blue 4.0 Pro series uses n-type TOPCon cell technology and achieves module efficiencies in the 21.8-23% range, while the newer Deep Blue 5.0 pushes beyond 24% efficiency at outputs up to 650 W, making it competitive for large MW-scale tenders. For a typical buyer, JA Solar represents a well-evidenced, bankable default choice. A fair comparison with ASM is not possible until that brand's credentials are independently verified.
