AIKO vs Jinko Solar - solar panel manufacturer comparison

AIKO, founded in 2009 and listed on the Shenzhen Stock Exchange (SZSE), and Jinko Solar, founded in 2006 and listed on the NYSE, are both Chinese Tier 1 bankable solar module manufacturers, but they occupy very different positions in the global industry. Jinko Solar is one of the world's largest module producers, with a declared module production capacity of 130 GW per year and a workforce of over 33,800 employees, consistently ranking among the top two global suppliers by shipment volume. Its NYSE listing and global distribution network give it strong visibility with institutional investors and large-scale project developers alike. AIKO operates at a significantly smaller scale but has carved out a clear identity as a technology leader - it has topped global module efficiency rankings for an extended period and has been recognized in industry awards, including the 2025 SolarQuotes Installers' Choice Awards in the Australian market, which is a strong proxy for performance-focused installer sentiment.

AIKO's portfolio of 144 models is built primarily around its proprietary ABC (All Back Contact) cell technology, which accounts for 73.6% of its lineup. By relocating all electrodes to the rear of the cell, ABC eliminates front-side shading losses, yielding an average module efficiency of 23.65% and a maximum of 25.2% - the higher figure in this comparison. Its average temperature coefficient of -0.271%/°C is also more favorable than Jinko's -0.308%/°C, meaning lower output losses during hot weather. With an average module power of 581 Wp and a maximum of 805 Wp, AIKO modules are well suited for space-constrained residential rooftop installations and premium commercial C&I projects where per-panel output and long-term yield matter most. Jinko Solar's much broader portfolio of 545 models - led by TOPCon technology at 39.4% of the range - offers average module power of 511 Wp and a maximum of 735 Wp, with average efficiency of 22.0%. This breadth and volume make Jinko the natural choice for utility-scale ground-mount projects demanding large, consistent supply, as well as for residential and commercial installers who value a proven, cost-competitive product with a globally recognized brand.

For international buyers choosing between the two, the decision hinges on project priorities. AIKO is the stronger pick where roof area is limited, peak efficiency is a differentiator, or a client is willing to pay a premium for technology leadership - its average warranty of 29.5 years also reflects manufacturer confidence in long-term module durability. Jinko Solar, with its 28.5-year average warranty, 130 GW production capacity, and deep logistics infrastructure, offers unmatched supply security and the flexibility to serve projects ranging from small rooftop systems to multi-hundred-megawatt solar farms across multiple continents.
