Product Summary

Longi Hi-MO X10 Scientist LR7-72HVH 640~670M is an N-type monocrystalline bifacial PV module adopting BC back-contact cell technology, with a maximum module efficiency of 24.8%. Designed with 144 cells (6×24), its power output ranges from 640W to 670W. Featuring outstanding low-light performance, low operating temperature and low degradation rate, it is ideal for large-scale ground power stations and commercial & industrial rooftop PV projects.

Core Advantages

1. High Power Conversion Efficiency Max module efficiency reaches 24.8% to boost power generation per unit area.
2. BC Back-Contact Cell Technology Less shading loss and optimized current transmission for better performance.
3. N-type Bifacial Design Excellent low-light response, extra power gain from reflected light captured by rear side.
4. Superior Reliability Low power degradation: less than 1% in the first year, only 0.35% annual degradation from year 2 to 30. 30-year linear power warranty.
5. Lower Operating Temperature BC-cell enables lower operating temperature to extend service life and improve energy yield.
