It has been recognized as a Tier 1 PV module supplier, including in S&P Global Commodity Insights' Tier 1 Cleantech Companies list. Sunpro Power, formally Zhejiang Sunpro Power Technology Co., Ltd., is a newer entrant founded in 2018 and headquartered in Yuhuan, Zhejiang province, with a much smaller production footprint, reportedly in the single-digit GW range in 2025, and sales exceeding 200 million USD across more than 100 countries; it has also achieved Tier 1 bankable status and is cited by some sources as ranking highly on BloombergNEF's Tier 1 list in recent years. Given its scale, longer track record, and backing from the large Chint industrial group, Astronergy has the stronger institutional footprint of the two. Both manufacturers center their current lineups on n-type TOPCon cell technology, though Sunpro also markets a meaningful HJT and back-contact portfolio alongside legacy PERC products. Astronergy's ASTRO N5s series targets premium residential rooftops with compact, high-power modules, while its ASTRO N5 range is aimed at commercial, industrial, and utility-scale ground-mount installations, emphasizing low degradation rates and high bifaciality. Sunpro Power's range spans roughly 430W to 725W panels covering both residential and commercial use, positioning itself as a mid-tier alternative with competitive efficiency figures and standard 25 to 30 year product and performance warranties, backed by common certifications such as TUV, CE, VDE, and UL. For a typical buyer in 2025, Astronergy is the more conservative, bankable default given its production scale, Chint backing, and longer market history, making it easier to finance and source through established distribution channels. Sunpro Power can be a reasonable alternative where its specific TOPCon, HJT, or back-contact products fit a project's technical requirements, but buyers should weigh its shorter operating history and smaller manufacturing base, and verify current bankability ratings and warranty terms directly, since these can shift quickly for less established manufacturers. \---LINKS--- \- https://www.astronergy.com/astronergy-named-tier-1-pv-module-supplier-in-sp-globals-first-cleantech-companies-list/ \| Astronergy named Tier 1 PV module supplier by S&P Global \| article \- https://taiyangnews.info/technology/topcon-and-bipv-modules-from-astronergy \| TOPCon and BIPV modules from Astronergy \| article \- https://www.energysage.com/supplier/22863/sunpro-solar/ \| Sunpro Solar - Profile & Reviews \| review \- https://www.enfsolar.com/sunpro-power \| Zhejiang Sunpro Power Technology Co., Ltd. company profile \| article \- https://www.solarquotes.com.au/panels/sunpro-power-review.html \| Sunpro Power Solar Panels Review \| review Written by claude-sonnet-5 from the figures above. ## Other comparisons - [Astronergy vs A.B.
