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 (Australian Solar Manufacturing), founded in 2009 and headquartered in Australia with a reported headcount of fewer than ten staff, and Zun Power, a Canadian manufacturer established in 2014 and based in Montreal, Quebec, are both small regional producers operating well outside the tier of large-volume global suppliers. Zun Power also markets its panels under the GMA Solar brand and describes itself as the only solar PV module manufacturer in Quebec, targeting commercial, industrial, agricultural, and institutional buyers across North America. ASM focuses on domestic Australian demand, appealing to buyers who value local sourcing. Neither manufacturer appears on Tier 1 bankability lists, and neither carries a stock exchange listing, which means project lenders for larger installations will typically require additional credit support regardless of which brand is specified.

Publicly available portfolio data for both companies is limited. ASM's catalogued products lean toward older monocrystalline modules in a relatively modest power range, reflecting a niche, low-volume operation with minimal public disclosure of current efficiency or warranty terms. Zun Power's documented range is broader - spanning from small specialty modules up to higher-wattage panels and incorporating PERC and TOPCon cell technologies alongside bifacial variants - which gives it marginally more versatility for varied commercial applications. Neither company publishes the kind of independently benchmarked degradation curves or third-party field-test data that are routinely available for major global brands, so prospective buyers should request certified test documentation and full warranty terms directly before specifying either.

For a typical buyer in 2025 without a firm regional sourcing requirement, neither ASM nor Zun Power would be the default recommendation over an established Tier 1 manufacturer. ASM is the more logical choice for an Australian buyer committed to domestically made product, while Zun Power better suits Canadian or North American commercial projects where local certification (CSA) and a regional supply relationship carry weight. Where those factors are absent, a Tier 1 manufacturer with a documented long-term performance track record will carry meaningfully less financing and warranty risk for most project types.
