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

Checking cache...

ASM, operating as Australian Solar Manufacturing Pty Ltd, is a small Australian company that positions itself as locally producing crystalline and monocrystalline solar panels. It is one of the very few manufacturers operating on Australian soil, and while that origin carries marketing appeal domestically, independent reviews of the company have found limited publicly available information on production scale, annual gigawatt output, or BloombergNEF Tier 1 bankability status. Its institutional footprint remains modest by global standards, and the brand is not found on major quarterly Tier 1 lists reviewed for this comparison.

JS Solar, established in 2007 and headquartered in Wuxi, Jiangsu province, China, is a more established export-oriented manufacturer. The company reports annual module exports in the vicinity of 2 GW, and its catalog - tracked by platforms such as EnergySage and ComparePV - spans roughly 137 panel models ranging from residential-friendly outputs up to approximately 670 W for commercial and ground-mount use. Its portfolio is predominantly PERC-based, with a smaller share of TOPCon modules beginning to appear in the lineup. Average efficiency across the catalog sits around 20 percent, with top-tier models reaching roughly 22.4 percent. Certifications confirmed in available sources include IEC 61215, IEC 61730, CE, and MCS, the last of which opens doors to UK residential markets. JS Solar does not prominently appear on BloombergNEF's Tier 1 list either, placing it in the mid-tier of Chinese exporters rather than alongside giants like JinkoSolar or LONGi.

For a typical buyer in 2025, JS Solar is the more documented and accessible of the two. Its broader product range, larger export volumes, and wider installer network give it a practical edge, particularly for commercial-scale projects outside Australia. ASM may be worth considering for buyers who specifically require domestically manufactured Australian product - for policy, supply-chain, or marketing reasons - but should be evaluated with careful due diligence given the limited independent benchmarking data available.
