Huasun vs Sunpro - solar panel manufacturer comparison

Huasun is a Chinese manufacturer, formally Anhui Huasun Energy Co., Ltd, founded in July 2020 and headquartered in Anhui province, specializing exclusively in n-type heterojunction (HJT) cell and module technology. It has been ranked a BloombergNEF Tier 1 PV module manufacturer since 2023 and describes itself as the world's largest HJT producer, with roughly 20 GW of annual HJT production capacity and cumulative shipments exceeding 8 to 13 GW (depending on the source date) to more than 60 to 80 countries. Sunpro Power, formally Zhejiang Sunpro Power Technology Co., Ltd, was founded in May 2018 and is headquartered in Yuhuan City, Zhejiang province. It has held BloombergNEF Tier 1 status since Q2 2022, maintained for three consecutive years, but operates at a much smaller scale, with production capacity reported around 2 to 3 GW as of Q1 2025. On institutional footprint, Huasun is the larger and more specialized player, with several times Sunpro's manufacturing scale and a longer, more consistent Tier 1 track record tied to a single advanced technology.

Huasun's product range centers on HJT modules marketed across residential rooftop, commercial and industrial rooftop, and utility-scale segments, with the company emphasizing higher energy yield and power density per installed area compared to TOPCon alternatives as a core selling point of its heterojunction architecture. Sunpro Power takes a more diversified approach, running PERC, TOPCon, and HJT production lines side by side across M6, M10, and M12 wafer formats, with panels spanning roughly 430 W to over 700 W aimed at residential, commercial, and utility-scale buyers alike, positioning it as a broader, more conventional Tier 1 supplier rather than a technology specialist.

For a typical buyer in 2025, Huasun is the stronger choice when high-efficiency HJT performance and a large, technology-focused manufacturer with deeper Tier 1 history are priorities, such as premium residential or commercial rooftops where space is constrained. Sunpro Power remains a reasonable, broadly bankable option for buyers who want technology flexibility (PERC, TOPCon, or HJT) or price competitiveness across mixed project types, though its smaller production scale gives it less long-term manufacturing depth than Huasun. The two are not strictly interchangeable: Huasun leans toward efficiency-driven projects, while Sunpro offers more versatility at a smaller scale.
