ASM vs G-STAR - solar panel manufacturer comparison
G-STAR has the broader catalog (36 vs 1 models). G-STAR leads on peak efficiency at 23.51%. G-STAR leans bifacial (86% of lineup).
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

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, trading as Australian Solar Manufacturing Pty Ltd, is a small-scale Australian panel maker and is generally described as the only domestic solar module manufacturer in Australia. Its founding history and annual production volume are not well documented in public sources, and the brand does not appear on BloombergNEF Tier 1 bankability lists, placing it firmly in a niche, locally-oriented segment rather than the international utility market. G-STAR Pte. Ltd., by contrast, is a Singapore-headquartered company founded in 2019 with a rapidly expanding manufacturing footprint: as of mid-2025 it operates a 1.5 GW solar cell and 1 GW module factory in Subic Bay in the Philippines, a 3 GW wafer facility in Indonesia, and additional capacity announced in Thailand and the UAE. G-STAR has not been confirmed on BNEF Tier 1 lists in available public sources, but its multi-GW scale and project financing across multiple markets give it a considerably stronger institutional profile than ASM.
ASM's product line, based on its ENF Solar directory listing, is centered on monocrystalline modules in lower wattage ranges associated with residential and small commercial rooftops, particularly in the Australian market where locally manufactured content carries regulatory and reputational appeal. G-STAR offers a broader technology portfolio spanning PERC, TOPCon, and HJT cells in both monofacial and bifacial configurations, with module outputs from roughly 360 W to above 700 W. That range makes it suitable for residential, commercial, and utility-scale ground-mount projects. G-STAR backs its modules with a 25-year product warranty and a 30-year linear power warranty with a stated annual degradation of 0.40%, and holds ETL, TÜV, and California CEC certifications.
For buyers outside Australia who need globally bankable panels at meaningful project scale, G-STAR is the more practical default in 2025 - it has verifiable multi-GW capacity, certified products, and an international distribution network. ASM retains a specific appeal for Australian buyers who prioritize domestic origin or local supply chains, but prospective customers should independently verify its current product range and warranty terms before committing.
