## Summary

LONGi Solar (LONGi Green Energy Technology Co., Ltd.) is a Chinese solar module manufacturer headquartered in Xi'an, Shaanxi province, founded in 2000. It ranks among the world's largest PV producers, shipping approximately 78 GW of modules in 2024, placing it second globally by volume. LONGi holds confirmed BloombergNEF Tier 1 status for both PV modules (Q2 2025, Q1 2026) and energy storage - making it one of very few manufacturers to hold dual Tier 1 recognition from BNEF. The company has a wafer production capacity reported at around 200 GW and back-contact (BC) module capacity reaching 50 GW by end of 2025. SunEvo Solar Co., Ltd. is a considerably smaller Chinese manufacturer headquartered in Hefei, Anhui province, founded in 2011. The company reports cumulative deployments exceeding 10 GW across more than 80 countries and claims Tier 1 status on its own marketing materials, but independent confirmation via BloombergNEF's publicly available tier lists could not be verified through available sources. In terms of institutional footprint and bankability, LONGi holds a substantially stronger position.

LONGi's European product portfolio is organized around clearly segmented use cases. The EcoLife series - anchored by the Hi-MO X10 and Hi-MO S10 modules using HPBC 2.0 back-contact cell technology - targets residential rooftop installations, including full-black aesthetic variants for urban settings. The Hi-MO X10 line also covers commercial and industrial (C&I) applications, with a fire-resistant variant for distributed generation on sensitive structures. The Hi-MO 9 serves utility-scale ground-mount projects. Module efficiency reaches up to 24.8 percent at up to 670 W output per panel. SunEvo Solar offers modules spanning a wide power range and covering PERC, TOPCon, HJT, and BC cell technologies, complemented by energy storage products under the SunArk brand and mounting solutions under SunRack - positioning itself as a one-stop provider. However, its European distribution network and project reference base appear significantly less developed than LONGi's.

For international buyers - particularly those in Europe sourcing modules for bankable residential or commercial projects - LONGi is the lower-risk choice, supported by verified Tier 1 status, a well-established European distribution and service network, and a strong record of utility and distributed generation deployments. SunEvo Solar may appeal as a cost-competitive alternative for buyers with less stringent bankability requirements, but the absence of independently verified Tier 1 standing and limited public project references mean it carries meaningfully higher procurement and financing risk compared to LONGi.
