## Summary

Huasun is a Chinese manufacturer specializing in heterojunction (HJT) solar cells and modules, founded in the early 2020s and now recognized as one of the world's largest dedicated HJT producers. It was named a BloombergNEF Tier 1 PV module manufacturer in record time for an HJT specialist, and by the end of 2024 it operated roughly 20 GW of cell and module capacity, with plans to reach around 40 GW by the end of 2025. Tongwei, by contrast, is a much larger and longer-established Chinese conglomerate with roots in aquaculture and feed production before expanding heavily into polysilicon, solar cells, and modules. It is also BloombergNEF Tier 1 rated, holds an AA bankability score, and sits among the top five global module makers with about 85 GW of annual production capacity, placing it alongside giants like Jinko, LONGi, Trina, and JA Solar. On institutional footprint and scale, Tongwei clearly has the stronger position, backed by deep vertical integration from polysilicon through to finished modules.

Product-wise, Huasun's catalog is built almost entirely around HJT cell technology, with a smaller TOPCon share, spanning its Himalaya and Everest G12R series. These range from compact residential rooftop modules up to large-format utility and commercial panels reaching into the 700W-plus class, with HJT's low temperature coefficient and strong bifacial performance (around 90% of its portfolio) often marketed as advantages for yield in hot climates. Tongwei's lineup centers on its TNC (TOPCon) platform, iterating from TNC 1.0 for cost-sensitive high-volume projects to newer TNC 2.0 and TNC 3.0 modules pushing toward 770W and 24.8% efficiency; it offers distinct residential bifacial modules around 450-455W alongside higher-power commercial, industrial, and utility-scale modules up to roughly 620-625W.

For a typical buyer in 2025, Tongwei's scale, long Tier 1 track record, and broader TOPCon-based product spread make it a safer default for large commercial or utility projects where bankability and supply reliability matter most. Huasun is a compelling alternative for buyers specifically seeking HJT's efficiency and bifacial gains, particularly on residential or space-constrained commercial rooftops, though its smaller scale means slightly less institutional history than Tongwei. The two are not simply interchangeable - the choice largely comes down to whether HJT's technical edge or Tongwei's scale and track record matters more for the project.
