Jolywood vs Longi Solar - solar panel manufacturer comparison

Jolywood is a Chinese manufacturer founded in 2008 and headquartered in Changshu, Jiangsu Province. The company listed publicly in 2014 and built its identity around n-type TOPCon cell technology, being among the earliest producers globally to industrialize that process at gigawatt scale. Module production capacity stands at approximately 10 GW per year, with cell capacity reaching close to 20 GW. Jolywood holds BloombergNEF Tier 1 status, confirming adequate bankability for project finance. LONGi Green Energy Technology, headquartered in Xi'an, Shaanxi Province and founded in 2000 by Li Zhenguo, has grown into one of the largest solar manufacturers on the planet. In 2024 the company shipped approximately 67.5 GW of modules worldwide and is targeting 100 GW of annual production capacity by the end of 2025. LONGi holds double Tier 1 recognition from BloombergNEF - covering both PV modules and energy storage - confirmed across Q2 and Q3 2025 and Q1 2026. On institutional scale and financing acceptance, LONGi carries a substantially stronger footprint than Jolywood.

Jolywood's product range centers on bifacial n-type TOPCon modules, a technology the company helped pioneer commercially. Residential-format panels exceed 22% efficiency, and the company is also active in HJT development. A notable structural advantage is Jolywood's position as the world's largest manufacturer of solar module backsheets, with roughly 30% global market share - giving it an integrated supply chain that few pure-play module makers can match. LONGi's portfolio spans a broader range of applications, from residential rooftop to large utility-scale ground-mount projects. Its flagship lines are built around proprietary back-contact cell architectures, including HPBC and HIBC variants. LONGi's HIBC cell has achieved a conversion efficiency of 27.81% under laboratory conditions, and the company introduced the world's first 700 W BC module with a panel efficiency of 25.9%. LONGi is particularly well positioned for utility-scale developers requiring high-volume, standardized, and easily financeable supply chains across multiple geographies.

For most international buyers - residential, commercial, or utility-scale - LONGi is the lower-risk default. Its production depth, persistent BloombergNEF recognition, and global distribution make it easier to finance and insure in virtually any market. Jolywood is a compelling and fully bankable alternative for buyers who specifically value early TOPCon bifacial expertise or an integrated backsheet supply chain. In practice, both brands offer high-efficiency n-type modules and competitive warranty terms, so for a project developer already working within Jolywood's distribution network, the two are broadly interchangeable at the technology level.
