Show series description

The AIKO Comet 3N72e (mono-glass) series is designed to maximize energy yield from every square meter of roof space – where high power density and real investment profitability are crucial. The key advantage is the n-type ABC (all back contact) cell technology, which enables a more efficient active surface, an aesthetically pleasing module design, and no performance loss due to traditional front-side elements.

In practice, the Comet 3N72e helps address common challenges in commercial installations: better performance under partial shading (reduced losses during the day), more stable power output in high temperatures, and slower degradation and high parameter repeatability over the long term. The mono-glass construction facilitates installations where optimal balancing between mass, mounting, and performance is a priority.

This solution performs exceptionally well on the rooftops of halls, warehouses, retail spaces, and public utility buildings, where limited space demands uncompromising efficiency and a rapid return on investment.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
