## Summary

LONGi Solar is a Chinese manufacturer headquartered in Xi'an, Shaanxi province, founded in 2000. It has held BloombergNEF Tier 1 PV module maker status through every quarter of 2025 and into Q1 2026, and additionally earned a BloombergNEF Tier 1 ranking in energy storage as of Q2 2026. PV-Tech has awarded the company an AAA bankability rating. With plans to ship approximately 80 GW of modules in 2026, LONGi ranks among the largest solar manufacturers in the world by volume. Solar N Plus New Energy Tech Co., Ltd. is a smaller Chinese producer operating five manufacturing bases across mainland China, Laos, and Indonesia, with a combined stated capacity of around 20 GW for cells and modules. The company holds a Dun & Bradstreet 5AA1 credit rating and has obtained SGS certification for its 182 mm TOPCon cells, but no BloombergNEF Tier 1 recognition has been confirmed in publicly available sources. In terms of institutional footprint and bankability credentials, LONGi holds a substantially stronger position.

LONGi has moved decisively beyond commodity PERC and TOPCon, centering its current lineup on proprietary back-contact architecture. The residential and prosumer range, sold under the EcoLife brand, features the Hi-MO X10 based on HPBC 2.0 (Hybrid Passivated Back Contact) technology and the premium Hi-MO S10 incorporating HIBC (Heterojunction Interdigitated Back Contact) cells. For utility-scale and C&I ground-mount applications, the Hi-MO 9 - also built on HPBC 2.0 and capable of up to 670 W output - serves as the flagship. Solar N Plus, by contrast, focuses on TOPCon-based modules using 182 mm cells, a format well-suited to residential rooftop and small commercial projects. Its portfolio appears aimed at price-sensitive buyers and smaller project developers who do not require the financing-grade credentials that project lenders typically demand.

For most international buyers - whether a homeowner seeking long-term manufacturer stability or a developer who needs bankable project finance - LONGi is the stronger default. Its technological lead in back-contact cell efficiency, persistent Tier 1 standing, and global service infrastructure are genuine differentiators rather than marketing claims. Solar N Plus may be a viable option where price is the overriding constraint and the buyer is comfortable with a manufacturer that lacks equivalent institutional recognition; the two brands are not interchangeable when project financing is on the table.
