## Summary

AIKO Solar is a Chinese manufacturer that has grown into one of the most recognized names in high-efficiency photovoltaics, achieving BloombergNEF Tier 1 status as of Q3 2024. Its annual production capacity stood at approximately 20 GW in early 2025, with reports suggesting a trajectory toward 35 GW by mid-2026, placing it within the top tier of global module suppliers by volume. YS Solar - formally Guangdong Yaosheng Solar Technology Co., Ltd. - is also a Chinese manufacturer, founded in 2009 and headquartered in Meizhou City, Guangdong Province. It operates at a significantly smaller scale, with roughly 1,200 employees and a stated facility area of 30,000 square meters; no BloombergNEF Tier 1 designation has been confirmed for the brand. AIKO therefore carries the stronger institutional footprint by a wide margin.

AIKO's defining product is its proprietary ABC (All-Back-Contact) cell technology, which relocates all electrical contacts to the rear surface to maximize light absorption. Its Neostar 2P series has been independently rated at module efficiencies up to 25%, the highest available in residential formats as of 2025, with a low temperature coefficient of -0.26%/°C and a 30-year linear warranty retaining above 88% of initial output. These characteristics make AIKO panels particularly well suited to premium residential rooftops and space-constrained commercial installations where every square meter counts. YS Solar, by contrast, offers a conventional portfolio of monocrystalline and polycrystalline modules in the 160-550 Wp range, using standard multi-busbar crystalline silicon technology. Its products are positioned toward cost-sensitive commercial or light industrial projects, and the company also markets ODM/OEM manufacturing services.

For most buyers evaluating these two brands in 2025, the choice is not close. AIKO competes with the global premium tier, backed by bankability credentials and verified field performance data. YS Solar is a smaller regional manufacturer without confirmed Tier 1 status, making it a higher-risk choice for projects requiring long-term finance or performance guarantees. YS Solar may remain relevant for buyers seeking low-cost ODM supply, but AIKO is the clear default for any project where efficiency, warranty security, or lender acceptance matters.
