## Summary

AIKO is a Chinese solar manufacturer headquartered in Shanghai, founded in 2009, and has held BloombergNEF Tier 1 bankability status since 2024; the company is now publicly listed on the Shanghai Stock Exchange. Its production scale runs into the tens of gigawatts annually, with shipments reported above 20 GW and planned capacity for its ABC cell technology extending much further, placing it among the larger global module suppliers. Heckert Solar, founded in 2001 in Chemnitz, Germany, manufactures exclusively in Germany across plants in Chemnitz and Langenwetzendorf, but its nominal output sits around 800 MW per year, a modest figure next to Chinese-scale competitors, and no confirmed BloombergNEF Tier 1 listing was found for the brand in public sources. On institutional footprint and production volume alone, AIKO holds a clear lead.

AIKO's product strategy centers on its patented ABC (All Back Contact) cell technology, which relocates electrical contacts to the rear of the cell to boost efficiency, powering model lines like Neostar and Infinite Ultra used across residential rooftops, commercial and industrial sites, and utility-scale ground-mount projects. Heckert Solar runs a more conventional, mixed technology lineup, spanning older PERC modules in its NeMo series to newer TOPCon cells in its Zeus series, and is typically positioned for buyers prioritizing European-made panels and straightforward, proven solutions for homes and smaller commercial installations rather than cutting-edge efficiency.

For a typical buyer prioritizing watts per square meter, proven bankability, and global brand recognition, AIKO is generally the stronger default choice. Heckert Solar remains a reasonable option where German manufacturing origin and shorter European supply chains matter more than headline efficiency, but on raw technical specifications and industrial scale the two brands are not closely matched.
