LONGi Solar 615W Solar Panel 144 Cell Bifacial LR7-72HGD-615M Commercial 720 panels per Container (Truckload)

LR7-72HGD-615M is a model that uses a number of technologies to bring durability and performance to the next level. The advanced HPDC cell technology ensures excellent power output.

Another advantage is the half-cut cell technology. LR7-72HGD-615M has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Not surprisingly, the efficiency of this module is quite high – 22.8%. 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 paid as much attention to durability as they did to performance. LR7-72HGD-615M is guaranteed to retain at least 87.4% of output after 30 years. Warranty for materials and processing for this panel lasts 12 years.

• 144 half-cut HPDC cells

Higher efficiency of up to 22.8%

The highest power output is guaranteed by LONGi LR7-72HGD-615M with an efficiency of up to 22.8%. Such outstanding performance is the product of advanced HPDC cell technology and an effective antireflective coating. This is notably above average, which will translate into significant additional savings over the course of operation.

Improved performance at hot temperatures

A high temperature coefficient translates to more energy as the temperature rises. Every 1.8°F increase over 77°F reduces the efficiency of your panel by just -0.28%.

High quality standards

LONGi strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Low degradation for a longer lifespan

These panels will lose no more than 1% of their power output in the first year of service. From the 2nd year to the 30th year, the average annual power decline will be no more than 0.4%. The module retains over 87.4% of its original output after 30 years. Guaranteed by LONGi.

Enhanced frame design

This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a strong, robust frame built from anodized aluminum alloy. A significant snow load of up to 5400 Pa may be supported by the model. The panel's back can support 2400 Pa, assuring that even the strongest winds won't damage your system.
