Sunlike Solar vs Sunpro - solar panel manufacturer comparison

Sunlike Solar is a Chinese module manufacturer based in Wuxi, Jiangsu, founded around 2010, with a relatively modest annual production scale reported at roughly 2 GW. Independent, large-scale verification of its bankability status is limited, and no clear BloombergNEF Tier 1 listing could be confirmed for the brand. Sunpro Power, formally Zhejiang Sunpro Power Technology Co., Ltd., is headquartered in Yuhuan, Zhejiang, founded in 2018, and has been cited by multiple industry trade listings as a BloombergNEF Tier 1 PV module supplier since the second quarter of 2022, with reported annual capacity in the 2 to 3 GW range spread across sites in Yuhuan and Wuxi plus an added Indonesian line. On institutional footprint, Sunpro currently presents the stronger case, given its documented Tier 1 recognition and broader export reach into over 100 countries, while Sunlike's standing rests mainly on catalog and distributor listings rather than independent bankability confirmation.

Both brands sell comparable product families aimed at similar buyers: monocrystalline PERC and TOPCon bifacial modules in the 400 to 700 watt range, positioned for residential rooftops, commercial installations, and some utility-scale ground-mount use. Sunlike's lineup spans older polycrystalline and M6-format panels alongside newer M10 TOPCon bifacial modules, with warranties typically quoted at 15 to 30 years and peak efficiencies cited around 23.5 percent in third-party comparisons. Sunpro's catalog leans more heavily on current-generation N-type TOPCon bifacial panels in the 440 to 595 watt class, generally paired with 15-year product and 30-year power warranties, though some retailer listings show inconsistent technology labeling that suggests looser quality control in how the catalog is documented.

For a typical buyer in 2025, Sunpro is the somewhat safer default thanks to its referenced Tier 1 bankability status and more consistent TOPCon-focused modern lineup, which matters for financing and long-term project insurance. Sunlike Solar is not necessarily inferior on paper, but its thinner independent verification and smaller, more mixed product generation make it a harder brand to recommend without direct lender or installer confirmation. In practice, for non-critical residential installs where financing bankability is less of a concern, the two brands may be close to interchangeable, but utility-scale or lender-backed projects should favor the better-documented Tier 1 track record.
