Tongwei vs ZNShine - solar panel manufacturer comparison

Tongwei is a Chinese manufacturer headquartered in Chengdu and part of the diversified Tongwei Group, which also has a long-established aquaculture business. The company has grown into one of the world's largest solar cell producers, with confirmed cell capacity exceeding 130 GW per year and module capacity estimated at 75-95 GW annually. Tongwei holds BloombergNEF Tier 1 status and was recognized as a Top Performer in the Kiwa PVEL 2025 PV Module Reliability Scorecard. ZNShine, formally ZNSHINE PV-TECH Co., Ltd., is based in Jintan, Jiangsu Province, founded in 1988 and active in the PV sector since 2006. The company operates approximately 10-12 GW of annual module production capacity across four facilities - three in China and one in Indonesia - and has entered a manufacturing joint venture in India. ZNShine has maintained BloombergNEF Tier 1 status continuously since 2015 and ranked among the top 15 global PV module manufacturers in 2024. In terms of overall institutional scale and market reach, Tongwei carries the substantially stronger footprint.

Tongwei's product lineup is anchored in n-type TOPCon technology, with a complementary range of HJT modules built on its proprietary THC cell platform, reaching output above 715 W at efficiencies around 23%. The company serves utility-scale ground-mount projects, commercial and industrial rooftops, and residential installations alike. ZNShine similarly targets all three segments, with its flagship offerings in 2025 including high-wattage n-type bifacial modules, HJT bifacial modules rated up to 750 W, and steel-frame modules designed for large ground-mount plants. ZNShine has also incorporated graphene into some cell designs as a durability-enhancement measure. Both manufacturers are competitive across the full range of project sizes typical in international markets.

For most international buyers - whether procuring for a utility tender or a commercial rooftop portfolio - Tongwei is generally the more defensible default, backed by its production scale, independent reliability test results, and the financial depth of its parent group. ZNShine represents a credible Tier 1 alternative, particularly for buyers seeking bankable modules at a competitive price point on mid-size commercial or ground-mount projects. The two brands are broadly interchangeable from a technical standpoint, so the final decision will often hinge on local distributor relationships, stock availability, and the specific warranty terms on offer.
