LR8-66HVD 640~670M

Built with advanced TaiRay wafer and BC cell technology, the LONGi Hi-MO X10 module delivers exceptional efficiency, reliability, and power generation performance for modern solar installations. With a power output of up to 665W and maximum module efficiency reaching 24.6%, it provides outstanding energy yield and improved project returns.

Designed for demanding environments, Hi-MO X10 offers lower operating temperature and enhanced stability, making it particularly suitable for industrial and commercial rooftop systems and high-temperature regions. Backed by a 15-year product warranty and a 30-year linear power output warranty, it ensures long-term reliability and consistent performance across its entire lifecycle.

A premium high-efficiency module engineered to reduce LCOE, maximize system value, and deliver stable energy generation for decades.

The LR8-66HGD 620W module is a high-performance bifacial solar solution designed for utility-scale and large commercial PV projects. Powered by advanced HPDC cell technology and a half-cell design, it delivers a rated output of 620W with up to 23.0% module efficiency, enabling higher energy yield per unit area.

With 0–3% positive power tolerance, less than 1% first-year degradation, and a low 0.4% annual degradation from year 2 to year 30, the module ensures stable and predictable long-term performance. Its high bifacial factor of 80% ±5%, combined with an excellent temperature coefficient (-0.28%/°C), provides significant additional energy gain under high irradiance and reflective ground conditions.

The robust double-glass structure, high mechanical load capacity (5400Pa front / 2400Pa rear), and IP68-rated junction box enhance durability in harsh environments. Backed by a 12-year product warranty and an industry-leading 30-year linear power output warranty, the LR8-66HGD 620W is a reliable choice for projects seeking long-term value and maximum returns.
