## Summary

GCL (GCL System Integration Technology) is a Chinese manufacturer and one of the largest solar module producers in the world by shipment volume. The company holds module production capacity of around 30 GW and shipped approximately 25 GW in 2024 - a year-on-year increase of over 50% - placing it among the top global suppliers by output. Despite this scale, GCL does not currently appear on the Bloomberg NEF Tier 1 bankability list, which evaluates financial standing from the perspective of project lenders rather than production quality alone. Hanersun is a younger Chinese manufacturer founded in 2015 and headquartered in Nanjing, with annual module production capacity of approximately 5 GW and cumulative deliveries exceeding 16 GW by end of 2025. The company has achieved BNEF Tier 1 status and earned a CCC+ rating in PV Tech's ModuleTech Bankability ranking as of Q4 2024, giving it a clear institutional edge in financed projects. Overall, GCL leads on raw production scale and supply security, while Hanersun holds stronger verified bankability credentials relative to its size.

GCL's product range centers on large-format TOPCon modules across the GEMINI, LOTUS, and ASTRO N series, with efficiencies confirmed above 23% and power outputs above 600 W. The company is also pushing into next-generation technology, having commissioned the world's first gigawatt-scale perovskite module factory in 2025. GCL modules are deployed across residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount projects, and competitive pricing tied to its manufacturing scale makes it attractive for volume procurement. Hanersun similarly focuses on high-efficiency TOPCon modules and was among the earliest manufacturers to introduce 600 W+ and 700 W+ products to the market. Its panels have received a Top Performer award from Kiwa PVEL and carry Australian CEC certification, signaling consistent real-world performance validated by independent testing. Hanersun also offers energy storage solutions alongside its panel range, making it a viable one-stop partner for installers seeking a broader product portfolio.

For buyers in financed commercial or utility projects where lender approval is required, Hanersun's verified BNEF Tier 1 and PV Tech ratings make project financing more straightforward. For large utility-scale procurement where supply volume, price compression, and chain-of-custody for silicon matter most, GCL's unmatched production footprint is a decisive advantage. For a typical residential or mid-size C&I buyer, both brands offer competitive TOPCon modules and the decision should come down to local distributor availability, installer preference, and current pricing. The two brands are not interchangeable in bankability terms, but for end-user energy performance they sit in broadly the same tier.
