## Summary

ASM, which stands for Australian Solar Manufacturing, is a small domestic manufacturer based in Australia and is generally described as one of the only companies producing solar panels locally on Australian soil. It operates at a niche scale and does not appear on BloombergNEF's Tier 1 bankability list, meaning it lacks the independent project-finance track record that institutional lenders require. LONGi Solar, by contrast, is a Chinese manufacturer headquartered in Xi'an, founded in 2000, and has held continuous BNEF Tier 1 status through at least Q3 2025, with the company also achieving a double Tier 1 ranking - covering both PV modules and energy storage - in Q1 2026. LONGi shipped more than 63 GW of solar cells and modules in the first nine months of 2025, representing close to 24% year-on-year growth, placing it firmly among the world's largest module producers. In terms of institutional footprint, LONGi is in a different category entirely.

ASM's product range is positioned primarily as locally made panels for the Australian residential and small commercial market, appealing to buyers who prioritize domestic supply chains and local warranty support. Cell technology specifics are not publicly confirmed in available sources, though the company's catalog is far narrower than global players. LONGi's Hi-MO series spans a wide range of applications: the Hi-MO 7 targets utility-scale ground mounts using n-type TOPCon cells, the Hi-MO 9 and Hi-MO X10 back-contact modules serve large commercial and C&I rooftop segments with confirmed efficiencies up to 24.8%, and the newly launched Hi-MO S10 brings heterojunction back-contact technology to residential rooftops at 25% module efficiency.

For most buyers in 2025, LONGi is the clear default - it offers bankable technology, a broad product family confirmed by independent lab tests, and the supply depth needed for projects of any scale. ASM is a reasonable consideration only when local manufacturing provenance is a firm procurement requirement, such as for certain government-funded Australian projects, and where lower volumes and a less established bankability record are acceptable trade-offs.
