Longi Solar vs ZNShine - solar panel manufacturer comparison

LONGi Solar (LONGi Green Energy Technology Co., Ltd.) was founded in 2000 in Xi'an, Shaanxi Province, China, and has grown into one of the world's largest solar module manufacturers by shipment volume. The company consistently holds BloombergNEF Tier 1 status for PV modules and, as of Q1 2026, was added to BloombergNEF's Tier 1 energy storage manufacturer list for the first time. In the first nine months of 2025, LONGi shipped over 63 GW of cells and modules, targeting approximately 80 GW of module shipments for the full year - a production scale that few rivals can match. ZNShine (ZNSHINE PV-TECH Co., Ltd.) traces its corporate roots to 1988 but entered the photovoltaic sector in 2006, with manufacturing facilities in Suqian, Changzhou, and Dali, China. ZNShine has appeared on the BloombergNEF Tier 1 PV module list consistently since 2015 and earned a B rating in PV Tech's bankability ranking. The company's stated production capacity stands at approximately 10 GW per year and its distribution network spans more than 60 countries. In terms of institutional scale and global market footprint, LONGi holds a substantially stronger position.

LONGi's current flagship product line centers on the Hi-MO X10, built on its proprietary second-generation Hybrid Passivated Back Contact (HPBC 2.0) technology, alongside the newly introduced Hi-MO S10 based on Heterojunction Back Contact (HBC) technology, which achieves module efficiency of up to 24.8%. These products are targeted at residential rooftop installations, commercial and industrial (C&I) projects, and utility-scale ground-mount systems - LONGi completed a 225.9 MW Hi-MO 9 project in Greece as a recent European benchmark. ZNShine positions itself across a similar range of use cases, offering monocrystalline modules in series such as the ZXM7-HiPro and ZXM6-NH, with efficiency ratings in the roughly 19.76-21.07% range according to available sources. A notable differentiator is ZNShine's graphene-coated glass, marketed for its self-cleaning properties - particularly relevant for large ground-mount arrays in dusty environments. ZNShine offers a 12-year product warranty with a 25-year (single-glass) or 30-year (double-glass) performance guarantee.

For international buyers choosing between the two, the decision largely comes down to performance tier and project requirements. LONGi is the stronger choice where maximum module efficiency, leading-edge cell technology, and top-tier bankability documentation are required - as in project-financed utility-scale or premium residential installations. ZNShine represents a credible, bankable mid-tier option with competitive pricing and a proven track record in distributed generation markets; it is a reasonable selection for standard commercial or residential rooftop projects where cost-efficiency is prioritized over peak performance. The two brands are not directly interchangeable in terms of technology ambition, but for a broad range of conventional installations, both are reliable, warranted, and financeable products from established Chinese manufacturers.
