## Summary

AIKO is a Chinese manufacturer headquartered in Shanghai, founded in 2009, that has grown from a cell technology specialist into a vertically integrated module producer with a reported nameplate capacity of around 20 GW as of early 2025. The company holds BloombergNEF Tier 1 status, a benchmark for bankability in project-financed installations, and has topped the TaiyangNews global module efficiency rankings every month since March 2023. Top Solar, by contrast, returns no meaningful presence in credible industry sources - no Tier 1 listing, no coverage in PV Tech, PV Magazine, EnergySage, or SolarReviews, and no verifiable production scale. On institutional footprint, AIKO is substantially better documented and more traceable.

AIKO's flagship technology is its ABC (All Back Contact) cell architecture, which relocates all electrical contacts to the rear of the cell, eliminating front-side shading losses and enabling mass-produced module efficiencies that the company reported breaking 24.4-24.8% in 2025 - the highest figure publicly documented for commercially available modules at scale. AIKO panels are positioned primarily as premium residential and commercial rooftop products for buyers who prioritize energy yield per square metre. The ABC platform is N-type, which inherently reduces light-induced degradation relative to older PERC architectures. For Top Solar, no confirmed cell technology, product family, or target application segment could be found in any authoritative source.

For a typical buyer in 2025, AIKO is the verifiable choice: its Tier 1 bankability, independently documented efficiency leadership, and growing installer network make it a defensible specification for premium rooftop projects where space is limited. Top Solar cannot be recommended in good faith at this time - not because the brand is necessarily poor, but because no credible public record exists to assess it against. Buyers should request third-party test data and warranty documentation from any supplier before proceeding.
