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 manufacturer headquartered in Zhuhai, founded in 2009, and best known for pioneering the mass production of ABC (All Back Contact) cell technology, which moves both electrical contacts to the rear of the cell to eliminate front-side shading losses. The company achieved BloombergNEF Tier 1 bankability status in 2024 and has been aggressively expanding capacity, with facilities currently operating at 10 GW and 14 GW scale and longer-term plans to reach 30 GW of total ABC cell and module capacity by 2029. RedSolar - formally Hunan RedSolar New Energy Technology Co., Ltd. - is also a Chinese manufacturer, founded in 2008 and headquartered in Hunan Province. It operates as a state-owned high-tech enterprise incubated by the 48th Research Institute of CETC (China Electronics Technology Group Corporation), drawing on roughly six decades of institutional semiconductor expertise. RedSolar claims to have delivered over 30 GW of PV products and to operate across more than 50 countries, though no confirmed BloombergNEF Tier 1 listing for the brand surfaced in publicly available sources. On institutional footprint and third-party financial validation, AIKO currently holds the clearer advantage.

The two brands occupy noticeably different product niches. AIKO's Neostar and Comet series are positioned as premium modules targeting quality-conscious residential and commercial rooftop buyers, with ABC cell efficiency figures that PV Magazine reported reaching a module-level world record of 25.2 percent at Intersolar 2024 and a typical average around 23.7 percent across the lineup. That performance profile, combined with a first-place finish in the 2025 SolarQuotes Australian Installers' Choice Awards, signals strong traction in markets where roof space is limited and per-watt yield matters. RedSolar, by contrast, appears oriented toward commercial, industrial, and utility-scale ground-mount applications, leveraging its CETC parentage and state enterprise backing to compete on large project procurement - particularly within China and across emerging markets in Asia, Africa, and the Middle East. The cell technology mix for RedSolar's current lineup was not independently confirmed in available trade-press sources.

For a typical buyer in mid-2025 - especially one financing a residential or small commercial rooftop installation through a Western bank - AIKO is the more straightforward default: it carries confirmed Tier 1 bankability, a documented track record on high-efficiency ABC modules, and growing independent installer validation. RedSolar is a credible option for large-scale procurement where CETC institutional backing and regional project delivery experience carry weight, but buyers requiring third-party bankability certification should seek updated confirmation before committing.
