## Summary

Jolywood, founded in 2008 and headquartered in Changshu, Jiangsu Province, China, is one of the more established manufacturers in the N-type solar segment. The company has been publicly listed on the Shenzhen Stock Exchange since 2014 and in 2022 became a subsidiary of Zheneng Electric Power, affiliated with Zhejiang Provincial Energy Group, giving it meaningful state-backed industrial support. Jolywood holds Tier 1 BloombergNEF bankability status and has built cell production capacity approaching 20 GW, with N-type TOPCon module capacity of roughly 10 GW. Sunova Solar, founded in 2016 and based in Wuxi, Jiangsu, is a considerably younger manufacturer that earned BNEF Tier 1 status in Q3 2023 and holds a B rating in the PV Tech Bankability Report. Its integrated production spans roughly 4 to 6 GW across factories in China and Vietnam. On institutional footprint alone, Jolywood holds the stronger position - its longer track record, stock listing, and state-affiliated ownership translate directly into greater lender confidence on financed projects.

Jolywood's portfolio is built almost entirely around N-type TOPCon technology, with bifacial double-glass modules ranging from all-black residential panels at around 425 W to high-power utility-scale modules exceeding 700 W in the Niwa Max series. The company was an early industrial-scale commercializer of N-type TOPCon, and its cells have reached a laboratory conversion efficiency of 25.4% using J-TOPCon 2.0 POPAID technology. Sunova competes across a comparable set of applications - residential rooftop, commercial and industrial, and utility-scale ground-mount - offering both bifacial TOPCon and HJT double-glass modules. Its TOPCon line has achieved efficiencies up to 22.9%, and its HJT modules offer low annual degradation rates that suit long-tenor financing structures. The presence of Vietnamese manufacturing capacity is a practical advantage for international buyers who need to diversify supply chains beyond Chinese-origin goods.

For most buyers, Jolywood represents the more conservative institutional default, owing to its deeper history, larger production scale, state-affiliated backing, and earlier adoption of N-type technology at commercial volumes. Sunova is a credible alternative - especially where HJT technology is preferred over TOPCon or where supply-chain origin flexibility is a procurement requirement. In markets where both brands are readily available through established distributors, the decision will often turn on price and local after-sales support rather than any fundamental technology gap, as the two manufacturers are broadly comparable in their core product offerings.
