Canadian Solar 615W (Pallet of 27) TOPBiHiKu6 N-type Bifacial TOPCon Solar Panel 

Silver Frame | +300mm/-200mm Cables, T6

Model: CS6.2-66TB-615 (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.

Key Benefits

The Canadian Solar TOPBiHiKu6 615W module combines N-type TOPCon cell technology with bifacial output, delivering high efficiency, strong real-world performance, and long-term reliability.

With up to 80% bifaciality, these panels can generate additional power from reflected light on the backside—making them ideal for ground mount systems, commercial installs, and high-production residential projects.

Key Features

• 615W High Output Panel
• N-Type TOPCon Technology
  • Lower degradation and improved long-term performance
• Bifacial Design (Up to 80%)
  • Increased energy yield from rear-side production
• Excellent Temperature Performance
  • -0.29%/°C for better output in hot climates
• Durability Tested
  • 5400 Pa snow load / 4000 Pa wind load
• Anti-LeTID & Anti-PID Performance
• Up to 23.3% Efficiency (higher wattage variants)

Ideal Applications

• Ground mount solar systems
• Commercial & industrial projects
• Agricultural solar (agrivoltaics)
• Large residential installs
• Reflective surface installs (gravel, sand, white roofs)

Because these are B Grade panels, warranty coverage is limited - see attached warranty document for more information.

Warranty:

• 2-Year Limited Product Warranty
  Covers defects in materials and workmanship that impact functionality under normal use, installation, and service conditions. Claims must demonstrate the issue is directly due to manufacturing defects (not handling, installation, or external factors).
• 10-Year Limited Performance Warranty
  Guaranteed to produce at least 90% of the labeled power output after 10 years, measured under standard testing conditions (STC), with normal testing tolerances applied.

Note: Performance output is covered separately from product workmanship and must be verified under standardized testing conditions.

Why This Panel?

If you're looking for maximum wattage per panel at a lower cost, this B Grade TOPBiHiKu6 delivers:

• More watts per panel → fewer panels needed
• Bifacial gain → higher real-world production
• N-type reliability → better long-term ROI
• Discounted pricing → stronger project economics
