## Summary

Talesun is a Chinese solar module manufacturer headquartered in Suzhou, founded in 2009 as part of the C&D Group, a Fortune Global 500 conglomerate, and has grown into one of the industry's established Top 10 producers. It has repeatedly appeared on BloombergNEF's Tier 1 PV module maker list, most recently for Q1 2025, and reports annual manufacturing capacity in the range of roughly 10 GW or more, with panels deployed across the US, Canada, Europe, South America and China. Solarspace, also based in China and founded in 2011, has scaled rapidly, reporting around 60 GW of cell capacity and 7.2 GW of module capacity by the end of 2023, and ranked second globally in solar cell shipments in 2024 according to PV InfoLink; it too has been consistently included on BloombergNEF's Tier 1 list. In terms of institutional footprint, Talesun benefits from a longer operating history and a large corporate parent, while Solarspace currently has the edge in raw cell manufacturing scale and recent shipment volume.

Talesun's product range spans PERC, TOPCon and heterojunction (HJT) modules, with TOPCon panels using SMBB busbar technology offered from roughly 440W to 715W, and HJT modules pitched at residential and commercial rooftop applications where higher energy yield is valued; the company also supplies utility-scale projects. Solarspace positions itself as a full in-house cell-and-module manufacturer offering both N-Type and P-Type products, with N-Type technology marketed for improved low-light performance and higher efficiency, and its output is distributed across residential, commercial and large-scale installations through six manufacturing bases. Both brands therefore compete across similar market segments rather than occupying clearly distinct niches, with N-Type/TOPCon-class technology now central to each company's premium offerings.

For a typical 2025-2026 buyer, both brands carry credible Tier 1 bankability status, so the choice often comes down to regional availability, warranty terms, and installer support rather than fundamental technology differences. Talesun's longer track record and larger corporate backing may appeal to buyers prioritizing established history and US/European distribution, while Solarspace's larger cell-manufacturing base and rapid recent shipment growth may suit buyers focused on newer N-Type technology and price-competitive large-scale procurement. Neither brand shows a decisive overall advantage, and both warrant standard due diligence on local warranty support before purchase.
