AIKO 620W Comet 1N N-Type ABC 72 Cell Silver Frame Gen 2 Solar Panel - Grade B

The AIKO Comet 1N N-Type ABC, 72 Cell, Silver Frame, Gen 2, rated 620 W, is offered here as Grade B stock — a solar panel built on N-Type ABC (All Back Contact) cells. AIKO's All-Back-Contact cell design moves every busbar to the rear of the cell, leaving the entire front face free to collect light.

What Grade B means

Grade B panels are electrically sound modules that carry minor cosmetic marks — scratches, blemishes or small dents to the frame or glass — picked up in transit or handling. They are sold at a discount to the same module in A-grade condition, which makes them worth considering for outbuildings, workshops, barns, ground mounts, off-grid systems and any array where cost per watt matters more than appearance.

Please read before ordering. All Grade B Item sales are final and sold as seen. Grade B items may have minor cosmetic imperfections (e.g., scratches, blemishes, dents, etc.) that do not affect functionality. ClearRay Solar makes no warranties of any kind, whether express or implied, respecting the performance, condition, suitability, merchantability, or any other quality of such items. Grade B Items are not eligible for returns, refunds, or exchange, and are exempt from the ClearRay Solar RMA policy. Product images are for illustrative purposes only and actual products may vary. Purchaser understands and agrees that assertion or enforcement of any manufacturer provided warranty is Purchaser’s sole responsibility.

About AIKO

AIKO Solar builds every module in its range on ABC (All Back Contact) cells, a structure it developed to move the cell's contacts out of the light path entirely. The design has taken an Intersolar Award and a Red Dot design award, and it is what puts AIKO modules at the top of the mainstream efficiency tables.
