## Summary

This confirms a key finding: SunKean is not actually a solar panel manufacturer but a solar cable/connector company, which changes the framing of this comparison significantly.

Astronergy is a large Chinese solar panel manufacturer, founded in 2006 and headquartered in Hangzhou, Zhejiang, as part of the Chint Group. It has been recognized as a Tier 1 PV module supplier by BloombergNEF and, more recently, by S&P Global Commodity Insights, and it operates at a substantial industrial scale, with module production capacity reported around 76 GW in 2024 and a target near 103 GW for 2025, alongside cumulative global shipments exceeding 150 GW. SunKean, by contrast, is a smaller Chinese company founded in 2013 and based in Wuxi, Jiangsu, that specializes in solar cables, wire harnesses, and PV connectors rather than in manufacturing solar panels themselves; it holds certifications such as TUV, ETL, CPR, and ISO for its connection products and has built distribution in Australia, Europe, Japan, and the US since 2015. On institutional footprint, Astronergy is by far the more established and bankable name in module supply, while SunKean operates in an adjacent but distinct segment of the PV supply chain.

Astronergy's product range centers on n-type TOPCon technology across its ASTRO series, spanning bifacial and monofacial modules for utility-scale power plants, commercial and industrial rooftops, and residential distributed generation, with recent flagship releases reaching 670-750 W and efficiencies above 24 percent. SunKean's product line, meanwhile, consists of solar cables, MC4-style and H4 Pro connectors, and interconnection hardware used to wire together panels, inverters, and storage systems, rather than panels intended to generate power directly; it briefly listed a small number of crystalline panel models (SMF310M, SMF375M series) that appear to be discontinued.

Given that these two companies serve fundamentally different roles in a solar installation, a "better panel" verdict does not apply. For a buyer selecting PV modules for a rooftop or ground-mount project, Astronergy is the relevant and far more established Tier 1 option; SunKean would instead be evaluated as a supplier of the cabling and connectors that link an Astronergy or other manufacturer's panels together, not as an alternative to them.
