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. \---LINKS--- \- https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/ \| Aiko steps up ABC transition with 11GW capacity upgrade \| article \- https://www.pv-tech.org/industry-updates/aiko-achieves-25-module-efficiency-in-mass-production/ \| AIKO achieves 25% module efficiency in mass production \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review - SolarQuotes \| review \- https://www.solarquotes.com.au/inverters/deye-review.html \| Deye solar inverters review - SolarQuotes \| review \- https://taiyangnews.info/technology/aiko-solar-abc-module-power-efficiency \| AIKO ABC module - making the most of each electron \| article Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
