## Summary

Hanersun is a Chinese solar module manufacturer headquartered in Nanjing, founded in 2004. The company holds BloombergNEF Tier 1 bankability status and earned a Top Performer designation in Kiwa PVEL's 2025 PV Module Reliability Scorecard. Its annual production capacity stands at approximately 5 GW, with cumulative module deliveries exceeding 16 GW through the end of 2025, and a presence spanning more than 100 countries. LONGi Solar, operating as LONGi Green Energy and headquartered in Xi'an since 2000, is one of the largest solar manufacturers globally by any measure. LONGi has maintained BNEF Tier 1 module status continuously and in Q1 2026 achieved a double Tier 1 designation covering both modules and energy storage. With plans to ship approximately 80 GW of modules in 2026 and in-house HPBC 2.0 cell capacity reaching 46 GW, LONGi commands a substantially stronger institutional and financial footprint than Hanersun.

Hanersun's product focus centers on HJT (heterojunction) and n-type TOPCon cell technologies, marketed under the HITOUCH series in both 210 mm HJT and TOPCon variants. These modules are well suited to commercial and industrial rooftop systems and mid-scale ground-mount projects where HJT's favorable temperature coefficient is an advantage. LONGi has built its current portfolio around its proprietary HPBC 2.0 back-contact platform: the Hi-MO 9 targets utility-scale ground-mount deployments, the Hi-MO X10 serves commercial and industrial buyers with module outputs up to 670 W and 24.8% efficiency, and the EcoLife series addresses residential rooftops with a compact, aesthetically clean format. LONGi's product breadth and distributor network in most international markets are considerably wider than Hanersun's.

For a typical international buyer - whether a residential installer, a C&I developer, or a utility-scale project financier - LONGi is the default choice given its production scale, long-standing bankability, and deep supply chain. Hanersun is a credible Tier 1 alternative worth considering when HJT technology is a specific requirement or when procurement strategy calls for diversifying away from the largest Chinese suppliers. The two brands are not fully interchangeable at utility scale, where LONGi's financial depth and track record carry real weight in project finance discussions.
