JinkoSolar 305W Cheetah Mono PERC MAXIM Cell Optimised Smart All Black Solar Panel - Grade B

The JinkoSolar Cheetah Mono PERC MAXIM Cell Optimised Smart All Black, rated 305 W, is offered here as Grade B stock — a solar panel built on Mono PERC cells. PERC cells add a rear passivation layer that reflects unabsorbed light back through the silicon for a second pass.

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 the Cheetah range

Cheetah was JinkoSolar's mono PERC range, the generation that preceded Tiger Neo.

About JinkoSolar

JinkoSolar is one of the world's largest module manufacturers. Its Tiger Neo range is built on n-type TOPCon cells with the company's HOT 3.0 process, which it rates for lower LID and LeTID degradation, better low-light output and an anti-PID guarantee, with certified salt-mist and ammonia resistance for coastal and agricultural sites.

Grade B stock is limited to the quantity held and is not restocked. For availability or pallet pricing, contact our sales team at sales@clearraysolar.com.
