Runergy 620W (Pallet of 31) Bifacial Dual Glass Solar Panels HY-DH132N11 Pro 620 B GRADE

What Does B Grade Mean?

B Grade solar panels are fully functional modules with minor cosmetic imperfections that do not materially impact performance. These may include slight frame scratches, glass blemishes, or discoloration from manufacturing or handling.

• Electrically tested and operational
• Meets core performance specifications
• Cosmetic imperfections only (not structural)
  

This makes B Grade panels an excellent value for ground mounts, large arrays, agricultural projects, or cost-sensitive installs where appearance is not critical.

See documents for more information on warranty.

 5-year product workmanship warranty and a 12-year performance warranty.

Shipping Notice for 600W+ Solar Panels

All solar panels rated 600W and above exceed liftgate size restrictions and cannot be unloaded via liftgate. Residential deliveries require the customer to provide appropriate unloading equipment (forklift, skid steer, or equivalent) at the delivery location. Failure to provide equipment may result in unloading by hand or re-delivery fees assessed by the carrier.

The Runergy HY-DH132N11 Pro 620W is a premium high-efficiency N-Type bifacial dual-glass solar module designed for demanding commercial, industrial, and large-scale photovoltaic installations.

Utilizing advanced 210R N-Type cell technology with a 132 half-cell configuration, the module delivers exceptional energy output, improved reliability, and industry-leading efficiency of up to 23.0%. 

Its bifacial dual-glass construction captures additional energy from reflected sunlight on the rear side of the module, increasing overall system yield while lowering the levelized cost of energy (LCOE).
