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
Huasun (Anhui Huasun Energy Co., Ltd.) is a Chinese manufacturer founded in 2020 and headquartered in Xuancheng, Anhui Province. Despite its short history, it achieved BloombergNEF Tier 1 bankability status in Q1 2023 - described at the time as record speed for an HJT-focused producer - and has maintained that ranking through at least Q4 2024. By end of 2024 the company had built 20 GW of annual HJT cell and module production capacity. Phono Solar Technology Co., Ltd., founded in 2008 and based in Nanjing, Jiangsu, carries considerably deeper institutional weight. It is a subsidiary of SUMEC Group, part of SINOMACH - the Chinese state-owned machinery conglomerate ranked 281st on the Fortune 500 in 2023 - and has held BloombergNEF Tier 1 status continuously since 2014, with annual production capacity of around 3 GW. On combined track record and financial backing, Phono Solar holds the stronger institutional footprint.
Huasun is a pure-play HJT specialist, with its entire production line dedicated to heterojunction cell technology. Its Himalaya G12-132 module delivered 730 W output at 23.5% conversion efficiency, as confirmed by the June 2025 TaiyangNews Top Modules listing, with 760 W modules announced for production by end of 2025. The low temperature coefficient and bifacial gains inherent to HJT make these panels well suited to utility-scale ground-mount projects and high-density commercial rooftop installations. Performance warranty runs 30 years with a stated maximum annual degradation of 0.3% from year two onward. Phono Solar covers a broader market, from residential rooftop through commercial C&I to utility-scale, offering both monocrystalline PERC and its newer Draco N-TOPCon line. The brand holds PVEL Top Performer recognition and DNV-GL certification, with standard 12-year product and 25-year performance warranties, and extended 15- and 30-year terms for bifacial models.
For buyers prioritizing cell technology leadership and maximum module efficiency, Huasun is the stronger pick. For those who value a long Tier 1 track record, state-backed financial stability, and a versatile portfolio covering the full range from residential to utility-scale, Phono Solar is the more conservative and well-rounded default. Neither brand represents a poor choice; the decision comes down to whether cutting-edge HJT efficiency justifies a younger company track record, or whether proven institutional reliability takes precedence.
