Show series description

The AIKO Comet 3N+72e (AIKO-A-MAE72Dw) is a bifacial double-junction module designed for maximum energy yield on limited surfaces and stable performance in both rooftop and ground-mounted installations. Central to its design is the N-type All Back Contact (ABC) technology—the absence of front busbars improves light utilization, while its aesthetics and uniform surface go hand-in-hand with higher operational efficiency during daylight hours.

In practice, the Comet 3N+72e handles typical installation challenges better: optimized performance under partial shading minimizes losses from dirt, leaves, or shadowing from roof elements, and excellent performance at high temperatures helps maintain yield during summer months. The application of dual-glass construction enhances durability in demanding environments and improves operational safety, which is crucial for commercial projects.

This is an excellent choice for C&I installations, solar farms, and projects prioritizing fast ROI, high power density, and predictable energy production—especially in locations where competitive modules suffer more from shading and intense heat.
