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

 B35/+400/-200mm/RY01

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.
