## Summary

Talesun is a Chinese solar module manufacturer founded in 2009, operating as a core enterprise of the C&D Group - a Fortune Global 500 conglomerate ranked 85th globally - and headquartered in Changshu, Jiangsu Province. It holds confirmed BloombergNEF Tier 1 status as of Q1 2025, meaning its modules are recognized as bankable assets by mainstream international project lenders and insurers. According to the company, annual module production capacity stands at 8 GW, and cumulative installed capacity from its modules has exceeded 36 GW across more than 20 countries. Techwise Solar Technology Co., Ltd. is also a Chinese manufacturer based in Jiangsu, with annual production capacity of approximately 1 GW. It does not appear on the BloombergNEF Tier 1 list and operates primarily as an ODM/OEM supplier, producing modules under contract for larger brands rather than building a standalone market identity. On institutional footprint and production scale, Talesun holds a considerably stronger position.

Talesun's current portfolio is built around N-type TOPCon technology. The TM7G-series spans 440 W to 715 W and includes all-black residential modules, bifacial dual-glass panels suited to commercial rooftops and ground-mount sites, and large-format high-wattage configurations for utility-scale projects. Active participation in Intersolar Europe 2024 and Intersolar North America 2025 underscores the brand's sustained engagement with Western buyers. Techwise Solar's "Sun-Pursuit" family covers both PERC and TOPCon technologies in monofacial and bifacial formats, with outputs running roughly from 420 W to 600 W. The lineup addresses residential and light-commercial needs, but because the company's primary route to market is OEM supply rather than direct branded sales, traceability and after-sales accountability can be harder to establish for end buyers or asset owners.

For most buyers - residential installers, C&I developers, or project teams requiring non-recourse financing - Talesun is the more defensible default choice. Its Tier 1 bankability simplifies project loans, its production scale reduces supply-chain risk, and its consistent trade-show presence reflects a long-term commitment to after-sales support. Techwise Solar may offer competitive pricing given its OEM orientation, but limited independent review data and absence from bankability rankings elevate risk for financed or large-scale installations. For cash-funded, cost-sensitive residential purchases it remains a plausible alternative, provided buyers independently verify certifications and warranty documentation before committing.
