Leapton vs AIKO - solar panel manufacturer comparison

Leapton Energy is a Tier 1 manufacturer founded in Kobe, Japan in 2012, with all module production carried out at its Changshu, Jiangsu facility established in 2017. The company claimed an annual production capacity of approximately 3 GW as of late 2024, and it holds Bloomberg NEF Tier 1 bankability status. Leapton was also named a Top Performer in Kiwa PVEL's 2025 PV Module Reliability Scorecard across four test categories. AIKO - formally Shanghai Aiko Solar Energy Co., Ltd. - traces its roots to 1996 and is listed on the Shanghai Stock Exchange. It achieved Bloomberg NEF Tier 1 status in 2024 and has been aggressively expanding cell and module capacity, with large-scale N-type ABC production lines coming online in Jinan. In terms of institutional footprint and technology investment, AIKO operates at a markedly larger scale.

Leapton's catalog is built around N-type TOPCon modules aimed at price-sensitive residential and commercial rooftop buyers who still require a bankable, independently tested product. Its value proposition rests on competitive pricing relative to larger Chinese brands while maintaining respectable reliability credentials. AIKO's product range takes a different approach: its flagship Neostar series uses proprietary All-Back-Contact (ABC) cell architecture, which positions all electrical contacts on the rear of the cell to eliminate front-side shading losses. The Neostar line targets premium residential rooftops and mid-scale commercial projects where maximizing output per square meter is a priority, while the higher-wattage Comet series addresses C&I ground-mount and large rooftop applications. AIKO has consistently topped global module efficiency rankings according to Taiyangnews since 2023, and in early 2025 it launched rooftop modules rated at 24.3% efficiency.

For a typical buyer in 2025, the choice largely depends on budget and efficiency goals. Leapton offers a solid, independently validated Tier 1 product at a lower price point, making it suitable where cost per watt matters most. AIKO suits buyers willing to pay a premium for best-in-class efficiency and a stronger long-term performance warranty - its 30-year warranty with a projected 90.6% retention at year 25 is notably more generous than Leapton's equivalent figure. These two brands are not interchangeable: Leapton competes on value, AIKO on peak performance.
