## Summary

Longi Solar, operating under the LONGi Green Energy brand, is a Chinese solar module manufacturer headquartered in Xi'an, founded in 2000. The company has maintained continuous BloombergNEF Tier 1 bankability status and achieved a double Tier 1 ranking in Q1 2026, covering both PV modules and energy storage - a distinction held by very few manufacturers globally. LONGi shipped 67.5 GW of modules in 2023, with 31.34 GW shipped in H1 2024 alone, placing it firmly among the top two or three largest module suppliers in the world. Its flagship product line is the Hi-MO series, built around the company's proprietary HPBC 2.0 back-contact cell technology, which has received TUV Rheinland certification and demonstrated measurably higher energy yield compared to standard TOPCon modules in independent field tests. LONGi serves residential rooftop, commercial and industrial, and large-scale utility ground-mount segments.

SunKean, headquartered in Wuxi, Jiangsu province and founded in 2013, is a manufacturer of solar cables, MC4 connectors, and wire harnesses for photovoltaic, energy storage, and EV charging applications. Every available source - including ENF Solar's manufacturer database and SunKean's own official website - consistently describes the company as a connection-component supplier, not a solar module manufacturer. SunKean does not appear on any BloombergNEF Tier 1 list for PV module producers, which is consistent with its position as a balance-of-system components provider rather than a panel manufacturer.

A panel-to-panel comparison between these two companies is not possible because SunKean does not manufacture solar modules. A buyer evaluating both names as potential panel suppliers should treat LONGi as the module manufacturer and SunKean as a potential cable and connector supplier for the same installation. It is strongly recommended to verify whether a brand name confusion has occurred before making any procurement decision premised on SunKean as a panel source.
