## Summary

Astronergy is a Chinese solar panel manufacturer founded in 2006 and operating as part of the CHINT Group, one of China's largest electrical equipment conglomerates. The company holds Bloomberg BNEF Tier 1 bankability status and, as of 2024, had shipped over 130 GW of modules worldwide, placing it among the top six module suppliers globally by volume. Module production capacity is reported at around 76 GW, with manufacturing facilities spread across China and Thailand. Sunova Solar Technology, founded in 2016, is a considerably younger entrant: cumulative shipments have exceeded 10 GW, with operational production capacity of roughly 5.5 GW reported in early 2024. Sunova also carries Bloomberg BNEF Tier 1 status and a CC+ bankability rating from PV Tech. On institutional footprint and manufacturing scale, Astronergy holds a clear lead.

Astronergy's current product focus is centered on TOPCon cell technology under its ASTRO N series, with PERC modules phased out of the primary lineup by late 2024. Its panels are deployed across residential rooftops, commercial and industrial buildings, and large utility-scale ground-mount projects. In the PVEL 2024 Scorecard, Astronergy was recognized as a Top Performer, ranking highly in six out of seven reliability test categories - a meaningful differentiator when assessing long-term project risk. Sunova offers both TOPCon and HJT modules, giving buyers access to two distinct high-efficiency cell technologies to match different project constraints. Its HJT line in particular suits space-limited installations where maximum output per square meter is the deciding factor.

For most buyers - residential, commercial, or utility-scale - Astronergy is the more straightforward default choice, given its longer track record, verified field reliability, and deeper global distribution network. Sunova is a credible Tier 1 alternative, especially where HJT technology is specifically required or where pricing makes it compelling. In pure panel-quality terms, both brands deliver competitive Tier 1 performance, and a buyer who receives a strong offer on Sunova should not automatically dismiss it in favor of the larger name.
