## Summary

GCL is a Chinese, Shenzhen-headquartered manufacturer and one of the largest vertically integrated players in global photovoltaics, holding BloombergNEF Tier 1 bankability status with annual module production capacity of roughly 35.5 GW. Heliene, by contrast, was founded in 2009 in Ontario, Canada, and operates on a smaller but fast-growing scale in North America, with factories in Canada, Minnesota and Florida and total US capacity now exceeding 1.3 GW, soon rising to more than 1.5 GW per year. GCL clearly has the stronger institutional footprint and global manufacturing scale, while Heliene has built its reputation as a trusted regional supplier for the US and Canadian markets.

GCL's catalog centers on N-type TOPCon modules rated up to around 605 W with efficiencies above 23 percent, alongside heavy investment in perovskite and tandem cell technology aimed at utility-scale, distributed generation and residential applications on a common platform. Heliene focuses on TOPCon modules made in North America, offering all-black panels tailored for residential rooftops as well as monofacial and bifacial modules for commercial, industrial and utility-scale projects, with a strong emphasis on domestic content and North American supply chain requirements.

For a typical international buyer, GCL's scale and pricing make it a practical default for most utility-scale and distributed projects outside North America, while Heliene is the more relevant choice specifically when domestic content rules or North American sourcing matter, such as for US utility-scale projects seeking tax credit eligibility. Both brands carry Tier 1 status, so bankability is broadly comparable, and the final decision should hinge on project location, pricing and the specific warranty terms offered by the local distributor rather than brand alone.
