Smart Insights (data-driven)
  • At 24.1% efficiency, this panel is on par with typical Back Contact 650-700W modules
  • Power density of 240.6 W/m² is 3.2 W/m² below Back Contact 650-700W median (243.8 W/m²) - needs more roof space
  • Temperature coefficient of -0.26%/°C matches the Back Contact 650-700W median
  • At 27.6 kg, this panel is 5.4 kg lighter than Back Contact 650-700W median (33.0 kg) - easier handling during installation
  • In the top 2% for efficiency among all Back Contact panels

Show series description

The Huayao Hyper B72 series are modules designed for maximum yield in large-scale installations – where high single-panel power output and efficient installation workflows matter. Variants in this family utilize large-cell formats and the half-cut layout, which helps minimize module losses and ensures stable operation under partial shading (e.g., from roof tiles, chimneys, or adjacent rows). In practice, this translates to more predictable energy production in real-world conditions.

Available in the range are also bifacial versions, capable of further harnessing reflected light from the ground – a clear advantage on white membrane roofs, gravel surfaces, or elevated setups. Designed for high reliability and compatibility with standard design infrastructure, they simplify selection for PV farms, warehouses, industrial facilities, and large commercial roofs. The Hyper B72 series stands out with its approach of 'more energy from the same footprint' without complicating the design, setting it apart from many series focused solely on catalog parameters.

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