## Summary

Both Sunpro and AIKO are Chinese-headquartered module manufacturers carrying BloombergNEF Tier 1 bankable status. Sunpro, founded in 2006 and NYSE-listed, has the larger institutional footprint: approximately 33,830 employees and a stated production capacity of 85-100 GW. AIKO, founded in 2009 and listed on the Shenzhen Stock Exchange, is a more focused operation built around a single proprietary cell architecture, with BC module shipments targeting more than 20 GW in the near term. For buyers whose financiers scrutinize manufacturer balance sheets, Sunpro's longer history and exchange listing give it a modest credibility advantage.

The two lineups diverge sharply on technology. Sunpro's 86-panel catalog is roughly 70% TOPCon and 100% bifacial, making it a natural fit for utility-scale ground mounts where rear-side albedo gain improves yield. Panels average 547 Wp, peak at 725 Wp, and carry a mean module efficiency of 22.8% (24.62% at the top end); the temperature coefficient averages -0.284%/°C. AIKO's 144-panel catalog is approximately 74% ABC (All Back Contact) technology - concentrating all metal contacts on the rear to maximize light capture - and only 24% bifacial, since ABC modules are primarily monofacial by design. The performance numbers step up noticeably: 581 Wp average, 805 Wp peak, 23.7% average efficiency (25.2% at best), and a slightly more forgiving temperature coefficient of -0.271%/°C. Both brands offer warranties in the 30-year range.

For space-constrained premium rooftops where every square meter matters, AIKO's efficiency edge and superior peak wattage make it the stronger technical choice in 2025. Sunpro is better positioned for large ground-mount or open commercial projects where bifacial gain and broad product availability carry more weight than peak cell efficiency. On utility-scale sites where either brand qualifies with project lenders, final selection will typically come down to spot pricing at the time of procurement.
