66HL5-BDV 710-735W

Product Overview

The 66HL5-BDV uses 132 N-type half-cells in a 66 × 2 layout. Its larger 2384 × 1303 mm format raises module power while retaining the bifacial dual-glass construction and low temperature coefficients of the platform.

The module is supplied in six power classes from 710 W to 735 W, with a 1500 VDC maximum system voltage, IP68 junction box and Class II safety rating. Connector type, cable length and packaging can be confirmed against each project requirement.

Key Features

• N-type monocrystalline cells with 132 half-cell configuration (66 × 2)
• Bifacial dual-glass construction with 80 ± 5% bifaciality
• Up to 23.66% module efficiency across the 710-735 W range
• Low Pmax temperature coefficient of -0.29%/°C
• IP68 junction box, Class II safety and Class C IEC fire rating
• 1500 VDC maximum system voltage and 35 A maximum series fuse
• 12-year product warranty and 30-year linear power warranty
• JK03M / MC4 / other connector options
