Bifacial Solar Panel 610W Longi N-Type 132 cells LR8-66HGD

Product Description

The 610W Longi N-Type Bifacial Solar Panel 132 cells LR8-66HGD belongs to the Hi-MO 7 series and is designed to maximize annual output with outstanding reliability. Its N-type cell with HPDC (High Performance Dual Cell) technology in half-cell format and double glass encapsulation (glass-glass) provide greater environmental resistance, lower operating temperature, and high bifaciality, resulting in more kWh per square meter and a lower LCOE. With 132 cells and a nominal power of 610 Wp, it is an ideal module for industrial self-consumption, ground-mounted plants, and large commercial rooftops where power, durability, and manufacturing consistency are required.

Main Features

• Nominal power of 610 Wp with approximate module efficiency of 22.6 % (595–625 Wp family).
• N-Type HPDC bifacial technology with high rear-side gain (≈80 % ±5 %), ideal for reflective surfaces.
• Double glass construction (2.0 + 2.0 mm) and anodized aluminum frame for maximum service life.
• STC parameters (610 Wp): Vmp ≈ 40.5 V, Imp ≈ 15.5 A; Voc ≈ 48.6 V, Isc ≈ 16.1–16.8 A.
• IP68 junction box with three diodes and 4 mm² cabling; standard lengths ±400/−200 mm (customizable).
• System voltage up to 1500 V DC and maximum series fuse 35 A (UL 29 A).

Advantages or Benefits

• More annual energy: bifaciality and the excellent power thermal coefficient (−0.29 %/°C) sustain production in hot climates.
• Long-term reliability: glass-glass construction and IP68 rating resist humidity, dust, and marine mist.
• Controlled degradation: <1 % in the first year and ≈0.4 %/year from year 2 to 30, with a 30-year linear warranty.
• Reduction of BOS: higher power per module means less structure, less cable, and less installation time per kWp.
• Design flexibility: electrical window suitable for high-current MPPT and long strings up to 1500 V DC.

Purpose or Applications

Perfect for commercial and industrial self-consumption on warehouse rooftops, ground-mounted plants, car parks and solar canopies, microgrids, and also for off-grid systems with high-power MPPT controllers. Bifacial gain is enhanced with high-albedo surfaces (light concrete, white gravel, or reflective sheets).

Technical Specifications

Compatibilities

Compatible with grid-tied and hybrid inverters that support strings up to 1500 V DC and input currents per MPPT equal to or greater than the generator's Isc (size protections with a 1.25 factor). Suitable for microinverters if the power, Voc, and Isc per input are within their limits. In off-grid or pumping systems, use MPPT controllers that respect the module's electrical margins. Always check that the Voc_total at the minimum temperature in your area does not exceed the equipment limit and size DC/AC cabling and protections according to current regulations.

The 610W Longi N-Type Bifacial Solar Panel 132 cells LR8-66HGD offers the ideal combination of power, efficiency, and durability for installations seeking maximum performance with long-term warranty.
