## Summary

JA Solar is a Chinese manufacturer headquartered in Beijing, founded in 2005, and one of the largest photovoltaic companies in the world by shipment volume. It holds Tier 1 recognition from both BloombergNEF and S&P Global Commodity Insights, and by mid-2025 its cumulative global module shipments had approached 300 GW, with annual module production capacity reported at over 100 GW. Runergy New Energy (Jiangsu Runergy New Energy Technology Co., Ltd.) is also a Chinese company, founded in 2013 and headquartered in Jiangsu Province. It achieved BloombergNEF Tier 1 PV Module Maker status for six consecutive quarters through Q1 2025, and by end-2024 held roughly 63 GW of cell manufacturing capacity and 23 GW of planned module capacity. Runergy has historically ranked among the global top three in solar cell shipments and supplies cells to a number of major module brands including, notably, JA Solar itself. In terms of institutional footprint and brand recognition among project developers and lenders, JA Solar holds a clear advantage.

On the product side, JA Solar's flagship module lines center on its DeepBlue series. The DeepBlue 4.0 Pro is an n-type TOPCon bifacial double-glass module suited to residential, commercial and industrial, and utility-scale ground-mount projects, offering a 30-year power warranty and a low annual degradation rate. The newer DeepBlue 5.0 pushes fifth-generation TOPCon technology further, with rated outputs reaching 650-670 W and module efficiency confirmed above 24%, targeting utility-scale and large commercial buyers. Runergy markets finished modules under its Hyperion brand, which covers bifacial panels for residential rooftops, commercial buildings, and off-grid applications. The company's cell R&D program has achieved a certified 26.55% full-area n-type TOPCon cell efficiency - a world-record figure as of its announcement - and mass-production cell efficiency sits in the 25-25.5% range. PV Magazine's module test ranked Runergy's n-type bifacial modules first for energy yield, suggesting competitive real-world performance.

For a typical buyer in 2025, JA Solar is the lower-risk default: its supply chain is larger, its module brand is more widely recognized by financiers and EPCs globally, and its DeepBlue TOPCon lineup is well-documented and field-proven at scale. Runergy is a credible and technically impressive choice - particularly for buyers who prioritize cell efficiency milestones or want a BNEF Tier 1 supplier at a potentially more accessible price point - but it carries slightly higher brand-recognition risk in markets where lender familiarity with the module label matters for project financing.
