JA Solar JAM66D45-620/LB 620W N-Type TOPCon Bifacial Dual Glass Solar Panel

Product Overview

The JA Solar JAM66D45-620/LB is a next-generation 620W N-Type TOPCon bifacial solar panel engineered for superior energy generation and long-term reliability. As part of the DeepBlue 4.0 Pro series, it features advanced N-Type cell technology, dual-glass construction, and a bifacial design that captures reflected sunlight from the rear side to increase total energy yield. With an impressive 23.0% module efficiency, 132 half-cut monocrystalline cells, and a robust dual-glass structure, this panel delivers exceptional performance even under challenging weather conditions. Its low temperature coefficient ensures better output in hot climates, while reduced annual degradation helps maximize lifetime energy production. Designed for 1500V DC systems, the JAM66D45-620/LB is ideal for residential, commercial, industrial, agricultural, and utility-scale solar projects. The IP68-rated junction box, reinforced aluminum frame, and high mechanical load capacity provide excellent durability and dependable operation for decades. **Key Features** * 620W High Power Output * N-Type TOPCon Cell Technology * DeepBlue 4.0 Pro Series * Bifacial Dual Glass Design * 23.0% High Module Efficiency * 132 Half-Cut Monocrystalline Cells * Excellent Low-Light Performance * Low Temperature Coefficient * Reduced Power Degradation * 1500V DC System Compatibility * IP68 Waterproof Junction Box * High Resistance to PID, Salt Mist, and Ammonia * Suitable for On-Grid, Off-Grid, Hybrid, and Net Metering Solar Systems * 30-Year Linear Performance Warranty
