## Summary

DualSun is a French manufacturer founded in 2010 and headquartered in France, employing between 50 and 100 people. It operates as a niche, innovation-driven company with a compact portfolio of 6 panel models, built around hybrid photovoltaic-thermal (PVT) technology developed at its R&D center in Marseille. Jinko Solar, by contrast, was founded in 2006 in China and is listed on the NYSE, employing over 33,000 people with a module production capacity of 130 GW per year. Holding Tier 1 bankability status and having crossed the milestone of 350 GW in cumulative module shipments by mid-2025, Jinko Solar ranks among the most dominant solar manufacturers globally - a position that gives it substantial leverage in pricing, logistics, and project financing contexts worldwide.

DualSun's core technical differentiator is its hybrid PVT panel, which simultaneously generates electricity and heat from the same roof surface, making it exceptionally well suited for residential rooftop installations where integration with heat pumps or domestic hot water systems is part of the energy solution. The company applies TOPCon cell technology across more than 83% of its portfolio, delivers a maximum panel efficiency of 22%, and backs its products with an average warranty of 30 years - among the longest in the industry. Jinko Solar's portfolio of 545 panels spans a far wider range of applications, with maximum power output reaching 735 Wp and maximum module efficiency of 24.8%, underpinned by proprietary N-type TOPCon cell development that has set multiple laboratory efficiency records. Its high-power modules are a natural fit for utility-scale ground-mount projects and large commercial or industrial (C&I) installations where power density, supply reliability, and bankability drive procurement decisions.

Buyers choosing between the two face a clear trade-off between specialization and scale. DualSun is the stronger fit for premium residential or small commercial projects where hybrid PVT functionality, European manufacturing, and a long 30-year warranty deliver concrete added value - particularly in markets with incentives favoring EU-made products. Jinko Solar is the more versatile choice for installers and project developers who need a broad product range, a proven global track record, and the financial security of a Tier 1, publicly listed manufacturer capable of supporting projects of any size.
