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 manufacturer founded in 2009 and headquartered in Guangdong Province, China. It achieved BloombergNEF Tier 1 bankability status in 2024 and reported an annual production capacity of roughly 20 GW as of early 2025, rising toward 35 GW by mid-2026, placing it among the top ten Tier 1 suppliers by volume. VDS Renewable - formally Jiangsu VDS Renewable Technology Co., Ltd. - is based in Changzhou, Jiangsu Province and is a considerably smaller operation, with a self-reported module output capacity of 2 GW and around 1,400 employees. No independent sources confirm a BloombergNEF Tier 1 rating for VDS Renewable, placing the two companies at markedly different levels of institutional recognition. AIKO's global manufacturing scale and Tier 1 status give it the stronger standing with project financiers and large commercial buyers.
AIKO's defining product line centers on its proprietary ABC (All Back Contact) N-type cell architecture, which relocates all electrical contacts to the rear of the cell and eliminates front-side shading losses. Mass-production module efficiencies have exceeded 24%, and the company set a confirmed world record of 24.4% for commercially available modules in mid-2025. These panels target premium residential rooftops and space-constrained commercial installations where per-square-meter yield is the priority. VDS Renewable offers a broader technology mix including PERC, TOPCon, HJT, and shingled formats in both mono- and polycrystalline configurations, suggesting a contract- or export-oriented catalog aimed at price-sensitive commercial and small utility buyers rather than a distinctive technology identity.
For a typical buyer in 2025, AIKO is the clearer choice when efficiency, warranty depth, and bankability matter - a 30-year linear performance warranty and confirmed Tier 1 status are meaningful differentiators. VDS Renewable may suit procurement where standard certifications such as CE, TUV, and IEC satisfy project requirements and lowest cost per watt is paramount, but the near-absence of independent third-party coverage makes it difficult to assess long-term reliability risk with confidence.
