Sunplus vs AIKO - solar panel manufacturer comparison

AIKO Solar (formally Shanghai Aiko Solar Energy Co., Ltd.) is a Chinese manufacturer founded in 2009 and headquartered in Shanghai, with large-scale production facilities spread across several Chinese cities including Yiwu, Foshan, Zhuhai, and Jinan. The company achieved BloombergNEF Tier 1 status in 2024, a designation that signals bankability for project finance, and has reported production capacity in the range of roughly 20 GW annually as of early 2025. Sunplus, operating as SUNPLUS OPTIMUM INC, is a considerably smaller manufacturer targeting the Americas, Caribbean, and Latin American markets, with a production base of approximately 1 GW per year; its BloombergNEF Tier 1 status has not been confirmed by available sources. In terms of institutional footprint and lender recognition, AIKO holds the stronger position by a wide margin.

AIKO's flagship Neostar series is built on N-Type ABC (All Back Contact) cell architecture, a technology that relocates all electrical contacts to the rear of the cell to eliminate front-surface shading losses and push efficiency toward theoretical limits. Independent reviews and the 2025 SolarQuotes Installers' Choice Awards rank AIKO panels among the highest-efficiency mass-produced modules commercially available, making the Neostar line best suited to premium residential rooftops and space-constrained commercial installations where maximizing output per square metre is the priority. AIKO also backs the Neostar with a 30-year performance warranty - an above-market commitment for the industry. Sunplus, by contrast, positions itself as a cost-competitive option for North American and Caribbean projects, offering bifacial PERC modules across a range of wattages, with UL certification and California Energy Commission approval making them eligible for US-market installations.

For a typical buyer in 2025, AIKO is the clearer choice where efficiency, bankability, and long-term warranty coverage are priorities. Sunplus may appeal to budget-sensitive buyers in the Americas who are working outside financed project structures, but the lack of confirmed Tier 1 status introduces residual financing risk that should be weighed against any upfront cost advantage.
