Canadian Solar 615W (Pallet of 27) TOPBiHiKu6 N-Type Bifacial TOPCon Solar Panel | B Grade
Silver Frame | +300mm / −200mm Cables | T6 Connectors
Model: CS6.2-66TB-615 | 27 Panels per Pallet | 16.605 kW Total Rated Power
The Canadian Solar TOPBiHiKu6 615W is a large-format N-Type TOPCon bifacial solar module designed for commercial, agricultural, and ground-mounted photovoltaic systems. Each panel delivers 615W of rated front-side output with 22.8% module efficiency, while its bifacial dual-glass construction allows additional generation from sunlight reaching the rear surface.
This pallet includes 27 B Grade modules, providing 16,605W of combined rated front-side capacity. These electrically tested, operational panels offer a practical option for projects where energy production and value take priority over cosmetic appearance.
Shipping Notice: Unloading Equipment Required
These 615W panels exceed our carrier’s liftgate size restrictions and cannot be unloaded using a liftgate. Customers must provide a forklift, skid steer, or equivalent equipment capable of safely unloading the shipment at the delivery location. Failure to arrange unloading equipment may result in redelivery fees or other carrier charges.
B Grade Product with Limited Warranty Coverage
These modules have minor cosmetic imperfections and carry a 2-year limited product warranty and a 10-year limited performance warranty. Review the applicable B Grade warranty document for complete terms.

What Does B Grade Mean?
B Grade panels are fully functional solar modules with minor cosmetic imperfections that do not materially affect electrical performance. Examples may include slight frame scratches, glass blemishes, or discoloration from manufacturing or handling. Appearance may vary between modules.
- Electrically tested and operational.
- Meets core performance specifications.
- Cosmetic imperfections rather than structural damage.
- Covered by the applicable B Grade limited warranty.
These panels are especially useful for ground mounts, farm installations, and other projects where a uniform cosmetic finish is less important.
Bifacial Energy Production
The module’s rear surface can generate electricity from reflected sunlight, increasing production beyond its 615W front-side rating when installation conditions allow. Elevated mounting, adequate row spacing, and reflective surfaces such as light-colored gravel can improve rear-side light exposure.
The 80% ±5% bifaciality rating compares rear-side performance with front-side performance under comparable test conditions. Actual additional energy production depends on ground reflectivity, mounting height, rear-side shading, and system layout.
Best Uses
- Ground-Mounted Solar Arrays: Installations with space for large-format modules and rear-side light exposure.
- Commercial and Industrial Projects: High-output arrays on compatible rooftops or available land.
- Agricultural Solar Installations: Farm and rural projects where output and value take priority over cosmetic uniformity.
- Large Residential Arrays: Properly designed systems with compatible mounting and electrical equipment.
- Reflective-Surface Installations: Sites that allow reflected sunlight to reach the back of the modules.
What’s Included
- 27 Canadian Solar TOPBiHiKu6 615W B Grade solar panels.
- Silver aluminum frames.
- Factory-installed +300mm positive and −200mm negative cables with T6 connectors.
Mounting hardware, inverters, batteries, and other system components are sold separately.

Frequently Asked Questions
How much rated capacity is included in one pallet?
Each pallet contains 27 panels rated at 615W each, totaling 16,605W or 16.605 kW of front-side capacity under standard test conditions. Actual production depends on weather, orientation, temperature, and system design.
Are B Grade panels functional?
Yes. These modules are electrically tested and operational, with minor cosmetic imperfections that do not materially affect performance. Their appearance may vary.
Does 80% bifaciality mean 80% more energy?
No. Bifaciality compares rear-side and front-side performance under comparable test conditions. Additional energy production depends on how much light reaches the rear surface.
Can this pallet be unloaded using a liftgate?
No. These modules exceed our carrier’s liftgate size restrictions. A forklift, skid steer, or equivalent unloading equipment must be available at the delivery location.
Which connectors are supplied?
This inventory is supplied with T6 connectors and +300mm positive / −200mm negative cables. Use approved mating connectors and follow the manufacturer’s connection requirements.
Will these panels work with my inverter?
Compatibility depends on the inverter’s voltage and current limits, string configuration, and cold-weather voltage calculations. Contact our team with your inverter model for help reviewing the module’s electrical specifications.
What warranty applies to these panels?
This B Grade inventory carries a 2-year limited product warranty and a 10-year limited performance warranty, with at least 90% of labeled output at year 10 under the applicable warranty terms.
