## Summary

Loom Solar is an Indian manufacturer founded in 2018 in Faridabad, Haryana, by brothers Amol and Amod Anand. It has grown into one of India's leading residential solar brands, operating a dealer network across hundreds of districts and reporting strong revenue growth in recent years. In late 2025 the company announced plans for a 1.2 GW gigafactory in Uttar Pradesh, signaling a push toward larger-scale industrial output. Loom Solar does not appear on the BloombergNEF Tier 1 bankability list as of mid-2025. Q-Cells was founded in 1999 in Bitterfeld-Wolfen, Germany, entered bankruptcy in 2011, and was acquired in 2012 by South Korea's Hanwha Group. Now headquartered in Seoul with engineering offices retained in Germany, it has built over 8 GW of U.S.-based module production capacity and holds confirmed BloombergNEF Tier 1 status. According to Wood Mackenzie, Q-Cells ranks first in both U.S. residential and commercial market share, giving it a substantially stronger institutional footprint globally.

Loom Solar's lineup targets residential and small-commercial rooftops primarily in India, where it offers ALMM- and BIS-certified TOPCon and HJT modules alongside inverters and batteries, positioning itself as a full-system provider for domestic buyers. Q-Cells addresses a wider range of use cases through two main product families: the Q.PEAK series uses PERC half-cut cell technology for residential and light commercial rooftops, while the Q.TRON line adopts N-type TOPCon cells for buyers seeking higher efficiency and lower annual degradation, a combination that also suits utility-scale and large commercial projects in North America and Europe.

For buyers in North America or Europe, Q-Cells is the clearer default - its Tier 1 status simplifies project financing, its operating history spans over two decades, and its product range covers every deployment scale. Loom Solar is the more relevant choice within India, where domestic certification, competitive pricing, and an extensive service network offset the absence of global bankability credentials. Because the two brands serve largely non-overlapping geographies and buyer profiles, a direct swap is rarely realistic in practice.
