## Summary

Deye is a Chinese manufacturer headquartered in Ningbo, Zhejiang, founded in 1990. It is primarily known as a solar inverter and energy storage system producer rather than a solar panel manufacturer - a distinction that is important for any buyer researching these brands side by side. Deye was named to S&P Global's inaugural Tier 1 Cleantech Companies List as a top PV inverter supplier. AIKO Solar, also Chinese, was founded in 2009 as a solar cell specialist and has since grown into a full module producer, achieving BloombergNEF Tier 1 Solar Module Maker status from Q3 2024 onward, with a production capacity of approximately 20 GW as of early 2025. AIKO carries a notably stronger institutional footprint specifically in the solar module segment.

AIKO's product identity is defined by its proprietary ABC (All Back Contact) n-type cell technology, in which all electrical contacts are relocated to the rear of the cell. The flagship Neostar series reached a confirmed 25 percent module efficiency in mass production, a world record for commercially available modules at the time it was announced. AIKO panels are positioned toward premium residential rooftops and space-constrained commercial installations where maximizing watts per square meter is a priority. The company backs its modules with a 25-year product warranty and a 30-year performance warranty with a low annual degradation rate. Deye, by contrast, does not produce solar modules; its catalog covers hybrid, grid-tie, and off-grid inverters alongside battery energy storage systems suited for residential, commercial, and utility-scale applications.

For a buyer seeking solar panels in 2025, AIKO is the directly relevant choice - it is a bankable, Tier 1 module maker with a technically differentiated, high-efficiency product line. Deye belongs in a different part of the system selection process: choosing an inverter or a battery. The two brands are complements rather than competitors, and a well-specified system could plausibly include AIKO panels and a Deye inverter operating together.
