## Summary

Panasonic is a Japanese electronics conglomerate headquartered in Osaka, with a solar manufacturing history dating back to 1975. For decades the company was regarded as a technology leader, particularly in heterojunction HJT cell development, and its EverVolt product line once ranked among the most widely specified residential panels in North America. That trajectory reversed in stages: the manufacturing partnership with Tesla ended in 2020, in-house panel production ceased in 2022, and the EverVolt line was subsequently produced under contract by REC Group. In April 2025, Panasonic announced the full discontinuation of its solar and battery storage business lines, ending its presence in the industry entirely. The brand no longer functions as an active manufacturer for new installations. Trina Solar, by contrast, is a Chinese manufacturer founded in 1997 and headquartered in Changzhou, Jiangsu Province. The company achieved a 100% bankability rating from BloombergNEF for the eighth time in 2025, and has been named a Kiwa PVEL Top Performer for eleven consecutive years. In 2024, Trina Solar shipped approximately 77 GW of modules, placing it among the top three producers globally, with cumulative worldwide deliveries exceeding 205 GW. In institutional standing and active market presence, Trina Solar has no peer in this comparison.

Trina Solar's product portfolio covers all major deployment contexts. The Vertex S+ series, built on N-type TOPCon technology, is targeted at residential rooftops and reaches efficiencies of around 22.3%, with an all-black variant available for design-conscious installations. Commercial and industrial projects are served by larger-format Vertex modules approaching approximately 23% efficiency, while utility-scale developers can access bifacial dual-glass panels in the high-power Vertex range, with the manufacturer reporting efficiencies above 24% on its largest formats. Flagship products carry a 30-year power output warranty, and residential modules are backed by a 25-year product warranty - both above typical industry baselines.

For any buyer evaluating these two manufacturers today, the conclusion is unambiguous. Panasonic has exited the solar market and cannot be selected for new projects. Trina Solar is a bankable, high-volume active producer with a well-documented reliability record and a portfolio suited to residential, commercial, and utility-scale applications alike. Between the two, Trina Solar is the only viable option.
