## Summary

Jinko Solar and Just Solar are both Chinese photovoltaic module manufacturers, but they differ dramatically in scale, market presence, and financial standing. Jinko Solar, founded in 2006 and headquartered in China, is consistently ranked as the world's largest solar module manufacturer by shipment volume - its annual module production capacity stands at 130 GW, and the company shipped 86.8 GW in 2025 alone, serving customers across more than 190 countries. Listed on the NYSE and holding Tier 1 bankable status, Jinko carries the financial credibility required by lenders and insurers on large-scale projects. Just Solar, based in Shanghai, is a considerably smaller B2B-oriented manufacturer with no Tier 1 certification and a much narrower product portfolio of 42 panel models, compared to Jinko's 545. Both manufacturers lead their respective portfolios with TOPCon cell technology, though Just Solar has a slightly higher TOPCon share at 52.4% versus Jinko's 39.4%. Jinko's peak panel efficiency reaches 24.8% against Just Solar's 23.82%, while average efficiencies across both portfolios are closely matched at around 22.0-22.1%.

Jinko Solar's broad portfolio and proven track record make it well suited to residential rooftop installs, commercial and industrial (C&I) systems, and utility-scale ground-mount projects alike. Its bifacial panel share of 31.9% gives developers flexibility for albedo-optimized ground installations, and eleven consecutive years as a PVEL Top Performer underline manufacturing consistency. The average warranty across its portfolio is 28.5 years, matching Just Solar's equivalent figure. Just Solar, with its higher TOPCon concentration and a competitive average temperature coefficient of -0.306%/°C, shows solid technical fundamentals, but its limited brand recognition, small portfolio, and absence from Tier 1 rankings position it as a niche supplier suited primarily to cost-sensitive private or self-funded projects where bank financing is not a prerequisite.

For international buyers - whether project developers, EPC contractors, or procurement teams - Jinko Solar is the lower-risk choice when financing, insurance, or long-term asset performance guarantees are in scope. Just Solar may appeal to buyers seeking competitive pricing on smaller volumes with a higher proportion of TOPCon modules, provided they are comfortable accepting the additional counterparty and bankability risk that comes with a non-Tier-1 manufacturer.
