## Summary

Hanersun is a Chinese solar module manufacturer founded in 2015 and headquartered in Nanjing, Jiangsu province. Originally operating as Csunpower before rebranding, the company has grown into a recognized mid-to-large-scale producer with annual manufacturing capacity reported at around 5 GW and cumulative shipments surpassing 16 GW by the end of 2025. Hanersun holds BNEF Tier 1 status, made its debut on PV Tech's bankability ratings with a CCC+ score in Q2 2024, and has earned a Top Performer designation from Kiwa PVEL - credentials that carry meaningful weight with project finance teams and independent power producers. Techwise Solar Technology Co., Ltd., also China-based and operating under the brand 绿鼎光伏, is a considerably smaller player reporting annual production capacity of approximately 1 GW. While Techwise holds standard international certifications including TUV, CE, ISO, and CGC and has supplied modules to more than 20 grid-connected projects worldwide, it does not appear on any publicly available BNEF Tier 1 list, which limits its access to project-finance-backed procurement. On institutional footprint, Hanersun holds a clear advantage.

Hanersun's product strategy centers on n-type TOPCon technology, marketed through its HITOUCH N-Series line, with modules exceeding 600 W and efficiency ratings confirmed by PV Magazine at up to 22.37% on certain models. The portfolio spans residential rooftop systems through commercial and industrial (C&I) applications to utility-scale ground-mount arrays, and bifacial configurations are available across the range. Techwise Solar's catalog covers PERC, TOPCon, and bifacial glass-glass panels, and the company positions itself partly as an ODM/OEM manufacturing partner for larger brands - a role that suggests solid production competence but reduces its visibility as a standalone consumer-facing brand. For C&I and utility-scale buyers, Techwise's manufacturing heritage may translate into competitive unit pricing, but the absence of bankability credentials complicates module sourcing in deals requiring independent lender approval.

For most international buyers - whether residential installers, C&I developers, or utility-scale EPCs - Hanersun is the more straightforward default: its BNEF Tier 1 standing and PVEL Top Performer recognition reduce financial risk and simplify the due diligence that lenders and insurers typically require. Techwise Solar is not a disqualifying option for buyers who can perform independent technical vetting and whose projects do not require bank-endorsed module sourcing, but it lacks the third-party validation that makes procurement decisions defensible to external stakeholders. Where project financing is involved, the gap between the two brands is significant; where it is not, the comparison narrows to price, lead time, and the quality of local technical support.
