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, as a solar panel manufacturer, returned limited and ambiguous results in publicly available industry sources. Searches surfaced primarily an Australian solar installation and service company trading under that name, with no identifiable module manufacturer carrying confirmed production figures, a BloombergNEF Tier 1 designation, or a traceable international supply record. Resun Solar Energy Co., Ltd. is a documented Chinese manufacturer founded in 2005, reporting production capacity of around 1 GW per year, ISO 9001 and ISO 14001 factory accreditations, and a distribution network spanning more than 80 countries. Resun has also served as a qualified panel supplier on World Bank-financed projects across Europe, Australia, and Africa. On institutional presence, Resun is the more verifiable of the two brands.
Resun's catalog spans roughly 420 W to 590 W, covering residential rooftops through mid-scale commercial and ground-mount applications. The company has adopted TOPCon cell technology across part of its lineup, which offers an efficiency and temperature-coefficient advantage over legacy PERC architecture. Modules carry TUV, IEC 61215, and IEC 61730 certifications and have been declared PID-free by PI Berlin lab. ASM's product families could not be confirmed from credible third-party sources; no independent test data or installer reviews for a panel manufacturer specifically under this brand name were found.
For a typical 2025 buyer, Resun Solar is the clearer default between these two. Documented certifications, an international project track record, and a reported 1 GW-scale manufacturing base provide a reasonable confidence floor. ASM, as a panel brand, lacks the public-domain evidence needed for a confident recommendation; any buyer receiving an ASM-branded panel offer should verify the precise legal entity and manufacturing origin before contracting.
