## Summary

Jinko Solar and SOMI represent vastly different tiers of the global solar PV manufacturing landscape. Jinko Solar, founded in 2006 and headquartered in China, is listed on the NYSE and stands as the world's largest solar module manufacturer by shipment volume, with a production capacity of 130 GW and a workforce exceeding 33,000 employees. The company holds Tier 1 (bankable) status, making it eligible for project financing from major financial institutions. In 2025, Jinko shipped approximately 86 GW of modules, surpassing a cumulative total of 390 GW delivered globally. SOMI, by contrast, is a significantly smaller and far less recognized brand, with no Tier 1 bankability status and a product portfolio of just 6 panel models. No substantial independent market reviews or global shipment data are available for SOMI, which suggests it operates as a niche or regional supplier with limited international footprint.

Jinko Solar's technology portfolio is led by its N-type TOPCon Tiger Neo series, which accounts for nearly 40% of its 545-panel lineup and achieves peak efficiencies of up to 24.8%, with a portfolio average of 22.0%. Over 31% of its modules are bifacial, making it well suited for utility-scale ground-mount projects, commercial C&I rooftops, and residential installations alike. The company's average temperature coefficient of -0.31%/°C is competitive and supports strong performance in variable climates. SOMI's entire portfolio relies on PERC (P-type) cell technology, with a maximum efficiency of 21.3% and a portfolio average of 20.8%. None of its panels are bifacial, and its temperature coefficient of -0.35%/°C is less favorable than Jinko's. One notable advantage of SOMI is a slightly longer average product warranty of 30 years compared to Jinko's 28.5 years, though this is difficult to evaluate without independent verification of the company's long-term financial stability.

For international buyers - including European installers and project developers - Jinko Solar is the substantially lower-risk choice, offering proven bankability, a deep and technically advanced product range, and a long track record of global deployments. SOMI may be considered only in cost-sensitive residential scenarios where Tier 1 status and bifacial capability are not requirements, and where the buyer can independently verify the manufacturer's warranty obligations.
