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
Solarspace is a Chinese manufacturer founded in 2011 and headquartered in China, with production bases spanning Xuzhou, Suqian, Chuzhou, Cambodia, and Laos - a footprint that partly allows the company to position products outside strict Chinese-origin trade restrictions. It has held BloombergNEF Tier 1 status since Q2 2023, signaling bankability for project-financed installations. Its cell capacity runs above 30 GW, though module output remains considerably smaller at around 5-6 GW per year, reflecting a business model weighted toward cell supply. AIKO - also Chinese, founded roughly in 2009 and sometimes referred to as Aiko Energy - secured BNEF Tier 1 standing in Q3 2024, a more recent milestone but one that still confirms lender acceptance. AIKO's module production capacity stands at approximately 20 GW. On institutional depth and longevity of bankable track record, Solarspace currently holds a modest edge, though both brands are recognized as credible tier-1 suppliers.
The two companies diverge sharply in technology focus. Solarspace operates across a mixed portfolio of TOPCon and HJT cell technologies - and retains some PERC lines - making it a broad-spectrum supplier suited to utility-scale ground mounts, commercial rooftops, and budget-sensitive residential builds. Its Lumina II series covers all three segments. AIKO has staked its entire roadmap on proprietary ABC (All Back Contact) cell technology, which places all electrical contacts on the rear of the cell, eliminating front-side shading losses entirely. The result is module efficiencies exceeding 24%, among the highest available in mass production as of mid-2025. AIKO's Neostar lineup targets premium residential rooftops, commercial installations where roof space is constrained, and increasingly ground-mount projects where peak watt density justifies the higher per-watt cost.
For a typical buyer in 2025, AIKO is the stronger choice where efficiency, long-term degradation rates, and aesthetic quality on residential rooftops are priorities, while Solarspace is more competitive in cost-driven utility or commercial projects where a broader cell technology mix and lower module pricing matter more than peak efficiency.
