Written summary
Haitai Solar is a Chinese manufacturer founded in 2006 and headquartered in Tangshan, Hebei. It earned BloombergNEF Tier 1 status for Q2 2025, confirming bankability for project-finance purposes, and has been recognized among China's Top 500 New Energy Enterprises. AIKO Solar, formally Shanghai Aiko Solar Energy Co., Ltd. (stock code: 600732.SH), was founded in 2009 and has scaled into a sizable international operation with six manufacturing plants in China, three R&D centers, more than 20 global branches, and over 15,000 employees. AIKO has held BNEF Tier 1 standing across multiple consecutive quarters. By headcount, manufacturing footprint, and international branch network, AIKO carries the stronger institutional presence of the two.
Haitai Solar addresses the full project spectrum - residential rooftops, commercial and industrial rooftops, and utility-scale ground-mount plants - offering standard high-power modules that have earned third-party recognition including Kiwa PVEL "Top Performer" status and TÜV Rheinland desert-module certification. AIKO differentiates itself through its proprietary ABC (All Back Contact) N-type cell technology, which the company reports achieving average mass-production cell efficiencies past 27% and module-level efficiencies approaching 25%, placing its panels among the most space-efficient crystalline silicon modules commercially available. According to PV Tech, AIKO is actively converting prior TOPCon and PERC lines to ABC via an 11 GW capacity upgrade, and backs its products with a 30-year performance warranty. Its lineup targets premium residential and commercial rooftop applications where high per-panel output justifies a higher upfront cost.
For a typical buyer in 2025, AIKO is the stronger choice where roof space is constrained and peak efficiency matters - its ABC technology lead, a 2025 SolarQuotes Installers' Choice Award win, and extended warranty terms are tangible advantages. Haitai is a credible Tier 1 alternative for buyers prioritizing module cost per watt over headline efficiency, but it does not yet match AIKO's technology differentiation or installer-level recognition in international markets.
