AIKO vs Jolywood - solar panel manufacturer comparison

Jolywood is a Chinese manufacturer founded in 2008 and headquartered in Changshu, Jiangsu Province, with manufacturing operations across Suzhou and Taizhou. The company was publicly listed in 2014 and is widely credited as one of the earliest industrialisers of n-type TOPCon cell technology, having pushed into GW-scale TOPCon production around 2016. Jolywood also holds a roughly 30% global market share in solar backsheets, giving it a vertically integrated position few peers can match. It has maintained a recurring presence on BloombergNEF's Tier 1 module maker list and reports a module production capacity in the range of 10 GW per year. AIKO is a Guangdong-based company founded in 2009 that has staked its identity almost entirely on N-type All Back Contact (ABC) cell technology, where all electrodes are moved to the rear of the cell to eliminate front-side shading losses. AIKO earned its first BNEF Tier 1 listing in Q3 2024 and is rapidly scaling output, with a new Jinan facility targeting 30 GW of combined cell and module capacity. On institutional footprint and production scale, Jolywood currently holds the longer track record.

In terms of product focus, Jolywood leans toward utility and commercial ground-mount applications, offering bifacial dual-glass TOPCon modules - including its ruggedised Windproof line rated from 570 W to 595 W for extreme climates - as well as standard residential formats. AIKO targets the premium end of the market, particularly residential and commercial rooftops where roof space is constrained. Its ABC modules have consistently ranked at or near the top of the Taiyangnews global module efficiency charts since March 2023, with mass-produced module efficiencies reaching up to 24.4%, and the brand offers a 30-year performance warranty with a notably low annual degradation rate of 0.35% per year after year one.

For a buyer prioritising maximum efficiency in limited roof space, AIKO is the stronger choice in 2025, particularly for residential installs. For utility-scale or harsh-environment projects where long-term bankability, broad product range, and deeper supply chain integration matter more than peak efficiency, Jolywood is the more established option.
