LONGi Solar 640W Solar Panel 144 Cell Bifacial LR7-72HVD-640M Wholesale 36 panels per pallet

LR7-72HVD-640M is part of the LR7-72HVD 625~645M Series — one of the most recent made by LONGi. These panels employ cutting-edge technologies to achieve superior efficiency and reliability.

The use of half-cut cell technology is an additional perk. The solar cells of LR7-72HVD-640M are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. As a result, the panel achieves an impressive efficiency of 23.7%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. LONGi provides an industry-leading 30-year warranty for extra linear power output and a 15-year warranty for materials and processing.

High efficiency of 23.7 percent

LONGi LR7-72HVD 625~645M panels fully use the firm's innovations, which LONGi has received several distinctions for. With TaiRay wafer & BC technology, more electricity can be produced per square foot of PV modules. As a result, there will be less clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.

Keeping the cool in high temperatures

Even under extreme heat, LR7-72HVD-640M maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.26% of efficiency for every 1.8°F over 77°F.

Quality and reliability

LR7-72HVD-640M undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. LONGi is committed to quality, safety, and dependability to ensure you get the finest.

Reliability and degradation resistance

LONGi guarantees slow deterioration over the next 30 years. The performance will decline by no more than 1% during the first year and then by no more than 0.35% every year after that. After the 30 years are over, your modules will retain at least 88.85% of their original performance. This 640 W LONGi solar panel also comes with a substantial 15-year warranty for materials and processing.

Improved frame design

LR7-72HVD-640M design makes it suitable for both residential and business rooftops. The use of a strong 1.18" frame composed of anodized aluminum alloy boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 2400 Pa, guaranteeing that your system will resist even the fiercest winds.
