  • At 23.7% efficiency, this panel is on par with typical Back Contact 600-650W modules
  • Power density of 236.9 W/m² matches the Back Contact 600-650W median
  • At -0.26%/°C, hot weather performance is typical for Back Contact 600-650W panels
  • 33.5 kg weight exceeds %!s(float64=1.1000000000000014) median by %!f(string=B) kg (32.4 kg) - heavier for installation crews
  • 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces

Show series description

AIKO Stellar 1N+ (AIKO-G-MCH72Dw) are dual-glass modules designed for maximum yield from the same surface area – with no compromises on longevity. Their key feature is the N-type ABC (All Back Contact) technology, which eliminates front busbars and utilizes light more effectively, translating to higher performance in real-world conditions, especially under weaker sunlight and in installations with limited mounting space. The glass-glass construction supports long-term operational stability, reduces the risk of degradation, and enhances resistance to environmental factors – crucial for solar farms, industrial rooftops, and projects near coastlines or agricultural areas. From an investor’s perspective, low degradation and long warranties are also important, as they facilitate energy production forecasting over time. The Stellar 1N+ modules also feature better performance at elevated temperatures, helping maintain yields during summer periods. This is a series for commercial and utility applications, where LCOE, reliability, and high power density matter.

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