## Summary

EGing PV is a Chinese solar manufacturer headquartered in Changzhou, founded in 2003 and publicly listed on the Shanghai Stock Exchange since 2011. The company is among China's earliest crystalline-silicon PV producers and has appeared on the BloombergNEF Tier 1 list, indicating a level of bankability recognised by project finance lenders. Its production capacity for cells and modules is reported at over 25 GW per year. LONGi Solar - formally LONGi Green Energy Technology Co., Ltd. - was founded in 2000 in Xi'an and has grown into one of the world's largest solar manufacturers by shipment volume. LONGi maintained continuous BloombergNEF Tier 1 status throughout 2025 and earned a rare double Tier 1 designation in Q1 2026 for both PV modules and energy storage. With plans to ship approximately 80 GW of modules in 2026, LONGi holds a substantially stronger institutional footprint than EGing PV on the global stage.

EGing PV's current product portfolio centres on n-type TOPCon technology, including the Star Pro series at 560-580 W with efficiencies up to 22.45%, suited for residential rooftops, commercial buildings, and small ground-mount installations. LONGi has moved beyond TOPCon into its proprietary back-contact technology stack covering HPBC 1.0, HPBC 2.0, and the premium HIBC tier. The Hi-MO 9 module - up to 670 W at 24.8% efficiency - targets large utility-scale projects, the Hi-MO X10 at up to 560 W serves residential and C&I rooftops, and the EcoLife series is positioned as a premium residential brand for homeowners. LONGi's HIBC cell achieved a verified conversion efficiency of 27.81% in 2025, the highest reported for any commercially produced silicon solar cell.

For most international buyers procuring modules for rooftop systems, commercial projects, or utility farms, LONGi is the stronger default choice given its technology leadership, scale of operations, and well-documented bankability across multiple market cycles. EGing PV is a credible mid-tier option where n-type TOPCon pricing is the primary driver and absolute peak efficiency is not critical. In price-sensitive tenders where module specifications are broadly comparable, the two brands can reasonably be treated as interchangeable - provided warranty terms and local service coverage are verified independently before commitment.
