Hi-MO9: Powering More with Every Detail

Superior Lifecycle Energy Output

Hi-MO9 delivers higher comprehensive power generation than TOPCon throughout the entire module lifecycle. While its bifaciality is slightly lower, it outperforms in temperature coefficient, degradation resistance, and tolerance to uneven light. With front-side power already 30W higher, the combined front and back power advantage grows beyond 30W across all stages of use. On the same land area, Hi-MO9 generates 6.5–8% more energy over its lifespan compared to TOPCon.

Lower BOS Cost, Higher System Efficiency

Thanks to its higher module output, Hi-MO9 enables up to 5% more system capacity than TOPCon using the same module size. This power gain translates to meaningful BOS cost savings—around $0.02/W less—by reducing the number of supports, mounts, and other installation requirements. For developers optimizing DC/AC capacity on limited land, Hi-MO9 is the clear economic choice.

Built to Last with Proven Reliability

Hi-MO9 combines advanced technologies—TaiRay wafers, back contact (BC) design, dual POE encapsulation, and thicker wafers—to deliver enhanced durability and low degradation. With smart design and industry-leading materials, it ensures 30 years of stable, high-performance energy output, even under challenging conditions like partial shading or high irradiance variation.
