## Summary

Goldi Solar is an Indian solar PV module manufacturer founded in 2011 and headquartered in Surat, Gujarat, with a workforce of 250-499 employees and a nameplate manufacturing capacity of 15.2 GW. The company holds Tier 1 (bankable) status from Bloomberg New Energy Finance, has received the Kiwa PVEL Top Performer designation for 2024, and exports to more than 20 countries worldwide. JA Solar, founded in 2005 and listed on the Shenzhen Stock Exchange (SZSE), is one of the largest solar manufacturers in the world, with production capacity exceeding 100 GW and module shipments of 79.4 GW in 2024 - roughly 40% growth year on year. JA Solar also holds Tier 1 status and earned the PVEL Top Performer designation for the tenth consecutive time in the 2025 scorecard. Both companies are financially credible choices for project financing, but the difference in scale is substantial: JA Solar's employee count of over 37,000 and its global distribution network dwarf Goldi Solar's current footprint.

JA Solar's portfolio of 524 panel models spans both mature PERC technology (Deep Blue 3.0 series, up to around 20.7% efficiency) and advanced TOPCon technology (Deep Blue 4.0 series, up to 23% efficiency), with a peak module power of 740 Wp and a maximum recorded efficiency of 24.4%. This breadth makes JA Solar a natural fit for utility-scale ground-mount projects, large commercial and industrial (C&I) installations, and residential rooftop markets where product availability and price competitiveness are paramount. Goldi Solar's portfolio of 110 models is narrower but notably higher in average output - at 513.6 Wp average versus 441.7 Wp for JA Solar - and carries an exceptional bifacial share of 83.6% compared to 44.3% for JA Solar. This positions Goldi Solar particularly well for bifacial ground-mount systems, agri-PV projects, and rooftop installations on highly reflective surfaces where rear-side gain materially improves annual yield. Goldi Solar's average efficiency of 21.17% also edges out JA Solar's portfolio average of 20.87%, reflecting a deliberate focus on premium, high-wattage modules.

For international buyers choosing between the two, JA Solar is the lower-risk default across most project types, given its unmatched scale, technology breadth from PERC through TOPCon, proven field reliability, and globally competitive pricing. Goldi Solar presents a compelling case for buyers who prioritize supply chain diversification outside China, or for projects where a high share of bifacial modules at above-average wattages is a key specification - areas where its portfolio holds a clear structural advantage over JA Solar's current offering.
