## Summary

Longi Solar, officially LONGi Green Energy Technology Co., Ltd., is headquartered in Xi'an, Shaanxi province, China, and was founded in 2000. Starting as a monocrystalline wafer specialist, it has grown into the world's largest solar module manufacturer by shipment volume, with reported module deliveries of approximately 67 GW in 2024 and a nameplate production capacity of around 120 GW per year. LONGi has held BloombergNEF Tier 1 status for many consecutive quarters and in Q1 2026 achieved a rare double Tier 1 ranking covering both PV modules and energy storage. Runergy - Jiangsu Runergy New Energy Technology Co., Ltd. - is based in Suzhou, Jiangsu province, and was established in 2013. The company reports a global cell manufacturing capacity of roughly 63 GW and a planned module capacity of 23 GW; it ranked among the global top three in cell shipments for three consecutive years between 2020 and 2022. Runergy first earned BloombergNEF Tier 1 status in 2023 and has retained it for at least six consecutive quarters, and it holds a BB bankability rating from PV ModuleTech. On institutional footprint, financing relationships, and overall scale, LONGi holds a clear advantage.

LONGi's product portfolio spans residential rooftop, commercial and industrial, and utility-scale ground-mount segments. The Hi-MO X10 line, built on its proprietary HPBC 2.0 back-contact cell architecture, targets residential buyers who prioritize efficiency and low-profile aesthetics, including a full-black EcoLife variant. Larger-format Hi-MO 9 modules are engineered for utility and C&I projects where levelized cost of energy is the primary metric. Runergy has positioned its catalog squarely around N-Type TOPCon bifacial dual-glass modules: the smaller HY-DH108N8B range (approximately 440-450 W) addresses residential and commercial rooftop needs, while the larger HY-DH144N8 series (570-580 W) is built for ground-mount farms and agrivoltaic projects. Runergy also operates a 2 GW module assembly plant in Huntsville, Alabama, which helps it serve buyers in markets with domestic-content requirements.

For most international procurement teams evaluating both brands for a utility or commercial project, LONGi is the lower-risk default - its scale, multi-year Tier 1 track record, and broad installer familiarity translate into easier project financing and more straightforward O&M sourcing. Runergy is a credible second choice, particularly for cost-sensitive buyers or those specifically sourcing N-Type TOPCon cells, and its Tier 1 status provides adequate bankability for lender due diligence. The two brands are not fully interchangeable: LONGi commands stronger recognition among EPCs and financiers, while Runergy can compete on cell pricing and serves niche segments such as US domestic-content projects.
