## Summary

Corab is a Polish manufacturer founded in 1993 in Bartoszyce, having built its reputation over more than three decades primarily as a producer of photovoltaic mounting structures and racking systems. The company employs over 300 people and declares a production capacity of 2.5 GW, though its solar panel portfolio is limited to just four models with a maximum output of 410 Wp and peak efficiency of 21%. Cell technology is not publicly disclosed. Jinko Solar, by contrast, is one of the world's largest vertically integrated PV manufacturers - founded in China in 2006, listed on the NYSE, and holding Tier 1 bankable status. With more than 33,800 employees and a stated production capacity of 130 GW, Jinko offers a portfolio of 545 panel models, including N-type TOPCon modules reaching 24.8% efficiency and 735 Wp peak power. The company has been a PVEL Top Performer for 11 consecutive years and has set a laboratory world record for TOPCon cell efficiency at 27.79%, verified by the Institute for Solar Energy Research Hamelin.

Corab's core strengths lie in its deep-rooted local presence across Poland and broader European markets, its established distribution and logistics network - spanning over 30 countries for its mounting systems - and the appeal of a domestically backed product warranty averaging 25 years. These qualities make Corab a practical choice for residential rooftop installers working within national subsidy programs, particularly for standard pitched-roof prosumer systems where local service and supply chain simplicity are priorities. Jinko Solar addresses the full spectrum of solar applications. Its TOPCon-based Tiger Neo modules, representing roughly 39% of the portfolio, deliver an average module efficiency of around 22% and a lower average temperature coefficient of -0.308 percent per degree Celsius compared to Corab's -0.339 percent per degree Celsius. With approximately 32% of its lineup comprising bifacial panels and an average warranty of around 28.5 years, Jinko is well positioned for commercial and industrial rooftop systems, utility-scale ground-mount projects, and any context where maximizing energy yield and long-term financial bankability are decisive factors.

For buyers choosing between the two, the decision follows project scale and market context. Corab offers a credible, locally supported option for installers focused on the Polish residential segment, but its narrow panel portfolio and undisclosed cell technology limit its competitiveness beyond that niche. Jinko Solar's combination of Tier 1 status, sustained investment in TOPCon technology, NYSE-listed financial transparency, and a vast product range makes it the more versatile and scalable choice for commercial, industrial, or utility-scale projects across Europe and global markets.
