Runergy 590W (Pallet of 31) N-Type Bifacial Dual Glass Grade B Solar Panels  HY-DH144N8 590W 

B35/+400/-200mm/MC4

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.

The Runergy HY-DH144N8 Plus 590W Grade B is a premium high-efficiency N-Type bifacial dual-glass solar module engineered for commercial, industrial, and utility-scale photovoltaic installations.

Utilizing advanced 182mm N-Type cell technology with a 144 half-cell architecture, the module delivers exceptional energy production, outstanding durability, and module efficiency of up to 22.8%.

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