The company self-describes a production capacity in the range of around 1 GW per year, though independent confirmation of that figure is limited, and no BloombergNEF Tier 1 designation was found in public sources. AIKO Solar, also Chinese-headquartered, achieved BloombergNEF Tier 1 bankability status as of Q3 2024 and has reported a nameplate production capacity of roughly 20 GW as of early 2025, placing it firmly among the global mid-tier leaders by volume. On institutional footprint - bankability ratings, financed projects, and international distribution networks - AIKO holds a considerably stronger position. In terms of product focus, Kingdom Solar targets a broad range of applications across residential rooftops and commercial ground mounts, offering standard mono- and polycrystalline modules without a distinctive technology differentiator evident from publicly available information. AIKO has staked its commercial identity on proprietary ABC (All Back Contact) cell architecture, which moves all electrical contacts to the rear of the cell to maximize light-capture area. That approach has allowed AIKO to claim consistent top rankings on the TaiyangNews efficiency charts for more than 34 consecutive months as of late 2025, with mass-produced commercial modules reaching up to 24.8% efficiency. The Neostar product line is oriented toward space-constrained premium residential rooftops and high-yield commercial installations, and it carries a 25-year product warranty. For most buyers in 2025 - particularly those prioritizing bankability, warranty depth, third-party performance validation, and access to cutting-edge cell technology - AIKO represents the more defensible default choice. Kingdom Solar may suit buyers seeking a cost-competitive, vertically integrated Chinese supplier for less demanding commercial applications, but the absence of Tier 1 recognition and limited independent review data make it harder to assess with confidence. \---LINKS--- \- https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/ \| Aiko steps up ABC transition with 11GW capacity upgrade \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review - SolarQuotes \| review \- https://www.solarreviews.com/manufacturers/zhejiang-kingdom-solar-energy-technic \| Zhejiang Kingdom Solar Energy Technic - SolarReviews \| review \- https://www.vicoexport.com/en/64212/tier-1-solar-panel-manufacturers-list-q4-2025/ \| Tier 1 Solar Panel Manufacturers List Q4 2025 \| article \- https://www.pv-magazine.com/2025/12/23/aiko-achieves-34-76-efficiency-for-2-terminal-perovskite-silicon-tandem-solar-cell/ \| Aiko achieves 34.76% efficiency for perovskite-silicon tandem cell \| article Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
