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
AIKO is a Chinese solar panel manufacturer founded in 2009 and headquartered in Guangdong, with manufacturing facilities also in Zhejiang. The company achieved BloombergNEF Tier 1 module supplier status in Q3 2024 and has scaled its cell and module production capacity to approximately 20 GW per year as of early 2025. FoxESS, by contrast, is a Chinese energy-technology company founded in 2019 and headquartered in Wenzhou, but it is not a solar panel manufacturer. FoxESS focuses exclusively on inverters, hybrid storage systems, and lithium battery packs, and holds BNEF Tier 1 recognition as an energy storage supplier rather than as a module maker. In terms of institutional footprint within the solar module market specifically, AIKO is the only one of the two with a direct presence.
AIKO's defining product is its ABC (All Back Contact) cell line, which relocates all electrical contacts to the rear of the cell to eliminate front-side shading losses. Commercially available ABC modules achieved a certified 24.4% module efficiency in 2025, placing them among the highest-efficiency mass-produced panels on the market, and their temperature coefficient sits around -0.26 percent per degree Celsius - meaningfully better than typical TOPCon or PERC competitors. The product range targets premium residential rooftops and space-constrained commercial installations where maximizing yield per square metre justifies the higher cost per watt. FoxESS, on the other hand, sells string inverters, hybrid inverters, and battery storage units that are designed to work alongside panels from any manufacturer. Buyers who see "FoxESS" in a solar quote are being offered a balance-of-system component, not a module.
For a buyer selecting solar panels in 2025, AIKO is a credible premium choice - particularly where roof space is limited and long-term yield matters - though its relatively recent entry onto the BNEF Tier 1 list means its bankability track record is shorter than incumbents like Jinko or LONGi. FoxESS cannot sensibly be placed in a panel comparison because it does not make panels; the two brands serve different parts of a solar system and are not substitutes for each other.
