Product Description

The UE650H-66HBD bifacial HJT module combines rectangle half-cut cells, N-type technology, and dual-glass symmetry for world-class performance in large-scale solar deployments. Designed for modern energy projects, it excels in both front- and rear-side energy capture—enhancing output on reflective surfaces like sand, snow, or white rooftops.

With its oversized footprint (2382×1134mm) and 132-cell configuration, it maximizes string voltage and reduces BOS (balance of system) costs. The module is built with a PIB-sealed frame, IP68 junction box, and MC4 connectors, ensuring robust outdoor endurance.

Whether for utility-scale PV farms or high-end solar buildings, this module offers a high-yield, high-longevity solution with strong ROI.

FAQS

Q :

Is this 650W panel compatible with standard PV racking systems?

A :

Yes. Despite its large size, the 1134mm width and 30mm frame profile ensure compatibility with most commercial racking and tracking systems.

Q :

How much extra output can bifacial gain provide?

A :

With highly reflective ground or rear exposure, the bifacial design can add up to 25–30% more output depending on the site.

Q :

What projects is this panel best suited for?

A :

It’s ideal for utility-scale solar farms, C&I installations, solar carports, and large ground-mount systems aiming for high power density.
