Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
AIKO is a Chinese solar manufacturer founded in 2009 and headquartered in Yiwu, Zhejiang Province, with its parent entity Shanghai Aiko Solar Energy Co., Ltd. listed on the Shanghai Stock Exchange. The company achieved BloombergNEF Tier 1 bankability status in 2024 and operates manufacturing capacity estimated at approximately 35 GW of solar cells per year. Gamko New Energy, formally Nantong Gamko New Energy Co., Ltd., was established in Nantong, Jiangsu Province in 2017, though the company traces its production experience to 2008. Gamko does not appear on BloombergNEF Tier 1 lists, and its annual production capacity stood at approximately 1.2 GW as of 2023. In terms of institutional footprint and bankability, AIKO holds a clear and substantial advantage.
AIKO's defining technology is its proprietary ABC (All Back Contact) cell architecture, which relocates all electrical contacts to the rear of the cell to eliminate resistive and shading losses at the front surface. This approach has pushed mass production cell efficiencies above 27.3% and module efficiencies to around 25%, placing AIKO consistently at the top of Taiyangnews global module efficiency rankings since early 2023. Its product range targets residential rooftop, commercial and industrial, and utility-scale ground-mount segments with a premium, efficiency-first proposition. Gamko New Energy covers a much wider wattage spectrum - from small off-grid panels in the low tens of watts through to modules rated up to 800 W - using TOPCon and PERC cell technologies. The company positions itself toward cost-sensitive buyers, smaller installation firms, and off-grid applications where maximum cell efficiency is secondary to cost per watt.
For most international buyers pursuing grid-tied installations - residential or commercial - AIKO is the more defensible default choice, supported by Tier 1 bankability, a genuinely differentiated cell technology, and independently verified efficiency leadership. Gamko New Energy is better suited to projects where price-per-watt and a broad module power range are the primary criteria, particularly in off-grid or budget-constrained deployments. The two brands are not interchangeable: AIKO competes in the global premium tier, while Gamko occupies a more value-oriented market segment.
