Introducing the LONGi LR7-72HVD 640–665M Series

Engineered for industrial and commercial rooftop applications, the LR7-72HVD series combines LONGi’s advanced TaiRay wafer and BC (Back Contact) cell technologies for exceptional reliability, long-term stability, and superior energy yield — even under high-temperature or harsh environmental conditions.

Key Product Highlights:

• Up to 24.6% module efficiency (model-dependent: ~23.7%–24.6%)
• High-temperature performance with advanced BC cell structure
• Excellent low-light power generation, ensuring energy yield even in cloudy or dusty environments
• IEC & UL certified for industrial and commercial installations

Warranty & Degradation:

• 15-year product warranty
• 30-year linear power output warranty
  • Max. 1% degradation in the first year
  • 0.35% annual degradation from year 2 to 30
  • Guarantees at least 88.85% power output after 30 years
• All efficiency values are based on STC (Standard Test Conditions); actual performance may vary under real-world operating environments.

Technology Notes:

• BC (Back Contact) Cell: eliminates front-side contact shading, allowing greater sunlight absorption and higher efficiency.
• TaiRay Wafer: LONGi’s proprietary high-purity wafer technology that enhances module reliability and temperature tolerance.
