## Summary

JS Solar, formally Yixing JS Solar Co., Ltd, is a privately held Chinese manufacturer headquartered in Wuxi, Jiangsu Province, with roots going back to 2004 and a dedicated production base established in 2007. Its annual manufacturing capacity is comparatively modest, reported around 600 MW, and available research does not place the brand on any recognized Tier 1 or BloombergNEF bankability list. Astronergy, the solar arm of the much larger Chint Group, was founded in 2006 in Haining, China, and has grown into one of the industry's major players, with module production capacity reported at roughly 76 GW in 2024 and a stated target near 103 GW for 2025. Astronergy is confirmed Tier 1 by Bloomberg, was named a Tier 1 PV Module Supplier in S&P Global's Cleantech Companies list, and holds an "A" bankability rating from PV Tech's ModuleTech report, giving it a substantially stronger institutional footprint than JS Solar.

JS Solar's catalog spans roughly 200W to 670W panels aimed at both residential and commercial rooftops, with a cell mix still weighted toward PERC alongside a smaller and growing TOPCon share, plus a limited bifacial lineup suited to smaller ground-mount projects. Astronergy has moved decisively into n-type TOPCon technology, which now makes up the large majority of its portfolio, and its ASTRO N series has been recognized in independent "best panel" lists for Australia in 2025; the company also scores well in PV Evolution Labs reliability testing, reflecting a product lineup built for both premium residential installations and utility-scale deployments.

For a typical buyer in 2025, Astronergy is the safer default: it combines confirmed Tier 1 and bankability credentials, larger-scale independent testing validation, and a more advanced TOPCon-based product line, which matters for financing, insurance, and long-term performance assurance. JS Solar may still suit smaller regional projects or buyers prioritizing a lower-volume, specialized supplier, but its lack of verified Tier 1 status and smaller production scale make it a less institutionally proven choice by comparison.
