Show series description

The AIKO Neostar 3N+78 Dual-glass (AIKO-A-MAE78Dw) is designed for investments where the maximum yield per square meter is key – without compromising on longevity. Using n-type cells with back-contact architecture eliminates front-side busbars and improves performance under real-world conditions, including when the module heats up or light is scattered. The dual-glass version is a practical solution for long-term durability – the rear glass supports laminate stability, reduces degradation risks related to moisture, and enhances material fatigue resistance.

For rooftops and complex installations, a major advantage is optimized performance under partial shading, preventing a single shadow from disproportionately blocking the entire module, thus reducing hotspot risks. Additionally, the series focuses on micro-cracking resistance, which is highly valued by installers for transportation and large-scale mounting.

This is an excellent choice for utility-scale solar farms, industry, and commercial applications – where lower BOS costs, stable performance, and high reliability over years are priorities.
