## Summary

Adani Solar is headquartered in Ahmedabad, Gujarat, India, and was established in the mid-2010s as part of the Adani Group's push into vertically integrated renewable energy manufacturing under Adani Green Energy. It has been recognized on Bloomberg New Energy Finance's Tier 1 module manufacturer list and currently runs roughly 4 GW of integrated cell-and-module capacity at its Mundra facility, with publicly stated plans to scale toward 10 GW by FY27. ET Solar, by contrast, is a Chinese manufacturer headquartered in Nanjing, founded in 2005, with a smaller production footprint in the 1.7 to 5 GW range depending on the reporting period, and it too appears on BloombergNEF's Tier 1 list. Between the two, Adani carries the stronger institutional footprint, backed by a large diversified conglomerate, an expanding domestic supply chain, and growing export ambitions, whereas ET Solar operates as a more modest, long-established but comparatively low-profile Chinese exporter.

On product mix, Adani Solar's catalogue spans monofacial and bifacial modules across PERC and TOPCon cell technology, with residential-oriented lines such as the Eternal Shine and Shine MonoPERC series (520 to 550W) and higher-wattage Eternal Pride and Elan Shine bifacial TOPCon modules aimed at commercial and utility-scale ground mounts; N-type TOPCon panels carry extended 30-year performance warranties. ET Solar's range is narrower and positioned more as a value or mid-market option, with standard monofacial panels in the 530 to 555W class, typically a 10 to 12-year product warranty and 25-year performance warranty, serving both residential and commercial rooftops without a strong emphasis on premium N-type cell technology.

For a typical buyer in 2025, Adani Solar is the more defensible default where backward-integrated manufacturing scale, a growing domestic and export track record, and newer TOPCon technology matter, particularly for utility-scale or large commercial projects. ET Solar remains a reasonable budget-conscious choice for smaller residential or commercial installations where long operating history and Tier 1 bankability are sufficient, but buyers should note its more limited local support in some markets and comparatively smaller production scale.
