## Summary

Resun Solar is a Chinese manufacturer headquartered in Suzhou, with founding accounts placing its establishment between 2005 and 2007 and roughly 15 years of manufacturing experience. The company operates a small number of factories with a production capacity cited around 1 GW, and its sales network reportedly covers more than 80 countries. Its modules carry standard IEC, CE and PID-free certifications, but available sources do not confirm a BloombergNEF Tier 1 listing for Resun. Sunova Solar, also China-based with factories spanning China and Vietnam, has an integrated production capacity of roughly 4.2 GW and has been repeatedly confirmed as a BloombergNEF Tier 1 module manufacturer in multiple quarterly reports through 2023 and 2024. Given the confirmed Tier 1 bankability status and larger manufacturing scale, Sunova appears to have the stronger institutional footprint of the two.

In terms of product focus, Resun Solar's catalog spans roughly 420W to 590W modules, including a meaningful share of bifacial panels, and the company positions itself for both ground-mount MW-scale projects and smaller residential rooftop systems. Sunova's lineup is broader in power range, from 400W to 720W, and includes dedicated product lines such as its S-size modules for space-constrained residential and small commercial rooftops, alongside higher-wattage Thor-series modules built for industrial rooftops and utility-scale ground-mounted plants. Sunova has been notably active in advancing TOPCon technology, having released high-efficiency n-type TOPCon modules reaching around 22.9% efficiency, and has also shown HJT modules at industry events, while Resun's portfolio leans on conventional mono and poly PERC-type cells with efficiencies up to about 22.9% in its most efficient models as well.

For a typical buyer in 2025, Sunova is generally the safer default choice for larger or financed projects, since its confirmed BloombergNEF Tier 1 status simplifies financing and gives lenders and EPCs more confidence, and its broader TOPCon and HJT technology offering suits both utility-scale and premium residential use cases. Resun Solar remains a viable option for smaller residential or mid-scale ground-mount installations where budget is the primary concern and Tier 1 financing requirements are not in play, but buyers should independently verify current bankability status before committing to large projects.
