## Summary

Trina Solar is a Chinese manufacturer headquartered in Changzhou, Jiangsu province, founded in 1997. The company ranks among the top global solar producers by cumulative shipment volume, having delivered over 205 GW to customers in more than 100 countries. BloombergNEF has continuously listed Trina Solar as a Tier 1 PV module manufacturer, including in Q1 and Q2 2025, reflecting strong bankability and broad access to project finance. Ulica Solar - formally Ningbo Ulica Solar Co., Ltd. - was established in 2005 in Ningbo, Zhejiang, and has grown into a mid-scale Chinese manufacturer with a confirmed Tier 1 standing and the EUPD Top PV Module Brand certification. Both companies operate globally and serve markets across Europe, Asia, and beyond, but Trina Solar carries a substantially larger institutional footprint, particularly within utility-scale and project-finance-driven procurement.

Trina Solar's current lineup is built around the Vertex platform. The Vertex S+ series serves residential and commercial rooftop installations, with the third-generation G3 modules spanning 465-495 W and reaching efficiencies up to 24.3% using the company's proprietary i-TOPCon technology, as reported by pv-magazine.com. Utility-scale and ground-mount buyers can access the Vertex N series, with bifacial dual-glass modules scaling up to 740 W in mass production. Ulica Solar addresses a comparable range of use cases, offering N-type TOPCon bifacial modules in formats reaching over 615 W for commercial and ground-mount applications, alongside PERC and full-black aesthetics options for residential rooftops. The company has expanded its European distribution notably in Poland, Germany, Italy, and the Netherlands, with products certified by TüV SüD and SGS.

For buyers prioritizing maximum bankability, a deep installer network, and straightforward project financing, Trina Solar is the stronger default. Ulica Solar is a credible and well-certified alternative for cost-sensitive residential or light commercial projects - particularly in European markets where its distribution is established. The technology gap between the two has narrowed meaningfully, as both brands now lead with N-type TOPCon bifacial products, making them broadly interchangeable at the specification level for many standard applications.
