AIKO vs Longi Solar - solar panel manufacturer comparison

AIKO is a Chinese solar manufacturer headquartered in Shanghai, founded in 2009, which achieved BloombergNEF Tier 1 bankability status in Q3 2024. Its annual module manufacturing capacity stands at roughly 20 GW, backed by R&D investment exceeding 3.2 billion RMB over three years and a patent portfolio surpassing 1,000 titles by mid-2025. LONGi Solar was founded in 2000 in Xi'an, Shaanxi, and has grown into one of the world's largest solar manufacturers, holding continuous BloombergNEF Tier 1 status for PV modules and earning a rare double Tier 1 recognition - covering both modules and energy storage - as of Q1 2026. LONGi's HPBC 2.0 cell capacity exceeds 57 GW including collaborative partners, and the company targeted approximately 80 GW in module shipments for 2026, having already shipped 67.52 GW in 2024. On institutional footprint, LONGi's two-decade operating history and manufacturing scale place it well ahead of AIKO among project financiers and utility-scale developers.

AIKO's entire lineup is built around its proprietary ABC (All Back Contact) N-type cell technology, which eliminates front-side metal contacts to maximize light absorption across the full module surface. The Neostar, Comet, Stellar, and Infinite series target premium residential rooftop and commercial-and-industrial applications where efficiency per square metre is the deciding factor. The Infinite series has reached verified module efficiency above 25%, and AIKO has consistently topped Taiyangnews global efficiency rankings since March 2023; full-black variants also carry fire safety class A certification. LONGi's Hi-MO series uses its HPBC 2.0 architecture - a hybrid of back-contact structure and passivation-contact technology - achieving up to 25.4% module efficiency in independent testing. LONGi addresses the full application spectrum: high-efficiency residential rooftop, C&I rooftop including a 2025-launched lightweight variant for low-load structures, and large utility-scale ground-mount projects, making it one of the few manufacturers that competes credibly across every segment.

For most international buyers, LONGi is the lower-risk default: a longer operating history, uninterrupted Tier 1 status, and a product range suited to every project size and budget. AIKO is the stronger pick when roof space is constrained and maximum efficiency is the primary criterion, or where full-black aesthetics and class A fire safety matter to the end customer. The two brands are not interchangeable - AIKO occupies a focused premium niche while LONGi serves virtually every buyer profile - but for quality-focused residential and light-commercial customers, AIKO has established itself as a credible and increasingly well-distributed premium alternative.
