PRODUCT OVERVIEW

LONGi LR8-66HVD-650M 650W Bifacial Solar Panel

The LONGi LR8-66HVD-650M is a 650W bifacial solar panel from the Hi-MO X10 series featuring HPBC 2.0 (Hybrid Passivated Back Contact) technology. Designed for commercial, industrial, and utility-scale photovoltaic power plants, it delivers high energy yield, outstanding efficiency, and a lower levelized cost of electricity (LCOE).

Thanks to its advanced Back Contact cell architecture, which eliminates conventional front-side busbars, the module maximizes light absorption while maintaining stable performance under high temperatures and partial shading. The result is consistently high energy generation and reliable long-term operation throughout the product’s service life.

Key Advantages:

• Advanced HPBC 2.0 Cell Architecture

The LONGi LR8-66HVD-650M from the Hi-MO X10 series features HPBC 2.0 (Hybrid Passivated Back Contact) technology. By relocating electrical contacts to the rear side of the solar cells, the module increases the active light-absorbing area, improves conversion efficiency, and delivers stable energy generation under real operating conditions.

• Higher Energy Yield with Fewer Modules

With a rated power output of 650W and a module efficiency of 24.06%, fewer panels are required to achieve the desired system capacity. This helps optimize installation space, reduce mounting structures, and lower overall Balance of System (BOS) costs.

• Bifacial Dual Glass Design

The bifacial glass-glass construction generates electricity from both the front and rear sides of the module by utilizing reflected sunlight. This design delivers higher energy yield, especially in ground-mounted PV systems, installations on light-colored roofs, and locations with high surface reflectivity (high albedo).

Applications:

The LONGi LR8-66HVD-650M is designed for commercial, industrial, and utility-scale photovoltaic power plants where high energy yield, predictable long-term performance, and a low Levelized Cost of Electricity (LCOE) are essential. The module supports systems with a maximum system voltage of 1500 V DC and is compatible with modern string inverters that meet its electrical specifications.
