## Summary

Goldi Solar is an Indian manufacturer headquartered in Surat, Gujarat, founded in 2011 by Ishver Dholakiya and now India's largest solar PV module producer, with reported annual manufacturing capacity of approximately 15.2 GW across multiple plants in Gujarat. A 1.2 GW TOPCon cell line is targeted for commissioning by early 2026. The company earned BloombergNEF Tier 1 bankability status in 2020 and was named a Kiwa PVEL Top Performer in 2024, a designation shared by roughly 50 manufacturers globally. LONGi Solar was founded in 2000 in Xi'an, Shaanxi, China, and operates on a fundamentally different scale - it shipped over 125 GW of monocrystalline wafers and more than 67 GW of modules in 2024, and holds a rare double Tier 1 from BloombergNEF covering both modules and energy storage. Approximately one in every four solar panels deployed globally originates from LONGi's factories. By any institutional measure, LONGi is the dominant player.

Goldi Solar's product lineup addresses residential, commercial, and utility-scale markets. Its HELOC Pro series is built on mono PERC technology, the HELOC Plus series incorporates TOPCon cells, and its newest IBC back-contact modules reach efficiencies up to 24.6%. The company exports to more than 20 countries including the USA, Germany, and UAE, with India as its core market. LONGi's current flagships are the Hi-MO 9 - optimized for utility-scale ground-mount at up to 670 W and 24.8% efficiency using proprietary HPBC 2.0 back-contact technology - and the Hi-MO X10 for C&I and residential rooftop applications. A lightweight Hi-MO X10 variant targets structurally constrained commercial roofs, while the EcoLife series covers residential distributed generation. LONGi also holds world records in HIBC cell efficiency and silicon-perovskite tandem technology.

For most international buyers, LONGi is the more defensible default: its scale, sustained Tier 1 recognition, and consistent PVEL Top Performer scores make project financing and lender approval more straightforward. Goldi Solar is a compelling alternative for buyers where Indian-origin supply chains carry regulatory or tariff advantages - a genuine differentiator in certain procurement frameworks - or where competitive PERC and TOPCon pricing on mid-scale projects is the primary criterion. Outside those specific contexts, the two brands are not yet interchangeable, though Goldi Solar's rapid capacity growth and improving certification record are narrowing the gap.
