Over two decades it has built a reported production capacity of around 10 GW spread across facilities in Nantong, Jiaxing, Shaoxing, and Yangzhou. It does not appear on widely cited BloombergNEF Tier 1 bankability lists, placing it in a mid-tier category for institutional recognition. AIKO Solar is a younger Chinese company that achieved BloombergNEF Tier 1 status in 2024, a distinction held by roughly 2 percent of global solar brands. AIKO has been aggressively scaling capacity, with operational ABC cell lines in Zhuhai and Yiwu and announced plans for BC module shipments exceeding 20 GW. In terms of institutional footprint and recent investor recognition, AIKO currently holds the stronger position. JS Solar offers a broad catalog spanning roughly 200 W to 670 W, covering residential rooftops, commercial installations, and storage-integrated systems. Its lineup draws primarily on PERC cell technology with a growing but still modest share of TOPCon modules, making it a reliable generalist option for budget-conscious commercial buyers. AIKO has staked its identity on ABC (All Back Contact) technology, a premium n-type architecture that relocates both electrodes to the rear of the cell to reduce shading losses and raise conversion efficiency. AIKO's approach earned the company a world-record module efficiency claim of 25.2 percent demonstrated at Intersolar 2024, and it took first place at the 2025 SolarQuotes Installers' Choice Awards in Australia. AIKO panels carry a 25-year product warranty and a 30-year performance guarantee, and are priced around the middle of the market despite their technology-forward positioning. For buyers prioritizing technology leadership and bankability assurance, AIKO is the more compelling choice in 2025, particularly for residential applications where ABC-driven efficiency gains translate directly into higher yield per square meter. JS Solar remains a reasonable option for cost-sensitive commercial or industrial projects where proven PERC or TOPCon modules and broad wattage availability matter more than cutting-edge cell architecture. \---LINKS--- \- https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/ \| Aiko steps up ABC transition with 11GW capacity upgrade \| article \- https://www.pv-magazine.com/2024/06/19/aiko-presents-abc-solar-module-with-world-record-efficiency-of-25-2-at-intersolar/ \| Aiko presents ABC module with world record 25.2% efficiency at Intersolar \| article \- https://www.solarchoice.net.au/products/panels/aiko-solar-panels-review/ \| AIKO Solar Panels - Independent Review by Solar Choice \| review \- https://www.energysage.com/supplier/20136/js-solar/ \| JS Solar - Profile and Reviews 2026 - EnergySage \| review \- https://comparepv.com/reviews/js-solar \| JS Solar Panels Review 2026 - Pros, Cons and Specs - ComparePV \| review Sources: \- \[Aiko steps up ABC transition with 11GW capacity upgrade\](https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/) \- \[Aiko presents ABC module with world record 25.2% efficiency at Intersolar\](https://www.pv-magazine.com/2024/06/19/aiko-presents-abc-solar-module-with-world-record-efficiency-of-25-2-at-intersolar/) \- \[AIKO Solar Panels - Independent Review by Solar Choice\](https://www.solarchoice.net.au/products/panels/aiko-solar-panels-review/) \- \[JS Solar - Profile and Reviews - EnergySage\](https://www.energysage.com/supplier/20136/js-solar/) \- \[JS Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/js-solar) Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
