## Summary

GCL, operating through its subsidiary GCL System Integration, is a Chinese manufacturer headquartered in Suzhou, Jiangsu, with roots going back to 2013 as part of the wider GCL Group. It has scaled to roughly 30 GW of annual module production capacity, having shipped over 16 GW in 2023 alone, which places it among the highest-volume solar suppliers globally. GCL is widely regarded as a bankable, Tier 1 manufacturer with production facilities spread across multiple Chinese provinces as well as Vietnam. Huasun Energy was founded in 2020 in Xuancheng, Anhui Province, and despite its short operating history was recognised as a BloombergNEF Tier 1 PV module manufacturer in Q1 2023, reportedly in record time for a company specialising exclusively in heterojunction technology. By end of 2024, Huasun reported approximately 20 GW of combined cell and module capacity. GCL holds the stronger institutional footprint by virtue of its decade-long track record and substantially larger cumulative shipment volumes.

GCL offers a broad technology mix that includes n-type TOPCon modules under the ASTRO N series, Cast-Mono formats, and legacy PERC products, covering utility-scale ground-mount, commercial and industrial (C&I), agri-PV, and residential segments. Current TOPCon modules in the ASTRO N line reach stated efficiencies of around 23.3%. Huasun builds its entire catalogue around heterojunction (HJT) technology: the Himalaya G12 series targets utility and large C&I projects with module outputs above 730 W and efficiencies around 24.5%, the Kunlun G12 dual-glass bifacial line is designed for vertical agrivoltaic installations, and the Everest G12R series addresses residential and smaller C&I rooftops at around 520 W. Huasun's HJT cells carry a notably low temperature coefficient of -0.24%/°C, providing a real-world yield advantage in warm or high-irradiance climates.

For buyers seeking reliable volume supply across diverse project types, GCL's scale, technology breadth, and long market history make it a sound default. Huasun is the stronger choice when peak module efficiency, superior temperature performance, or HJT-specific design requirements are the primary selection criteria. The two brands are not interchangeable in positioning: GCL competes on portfolio depth and production scale, while Huasun is a premium-efficiency specialist that is still building its long-term shipment track record.
