LR7-72HVH Product Description
The LONGi LR7-72HVH 640-670M is a high-performance bifacial solar module designed for large-scale utility and industrial solar projects. Offering power outputs ranging from 640W to 670W and achieving a module efficiency of up to 24.8%, it delivers industry-leading performance, maximizing energy production per square meter.
Featuring BC-cell technology, the module offers high efficiency with low degradation. Its 80% bifaciality allows for enhanced energy generation on the rear side, particularly on reflective surfaces such as snow, sand, and other high-albedo ground. Built with dual 2.0mm tempered glass and a durable anodized aluminum alloy frame, the LR7‑72HVH is designed to withstand harsh conditions, including 5400Pa front load and 2400Pa rear load, as well as hail resistance up to 25mm at 23m/s.
The LR7-72HVH 640-670M is perfectly suited for utility-scale solar farms in high-irradiance regions like the Middle East and Australia, where performance under high temperatures and dust resistance is crucial. Its bifacial design makes it especially effective in Southeast Asia and South America, where reflective surfaces enhance rear-side energy generation. With its 1500V system compatibility and durable construction, this module is a top choice for large installations in North America and Europe, delivering high performance and reducing system costs over time.

Longi Solar Product Details
Each Longi solar panel comes with labels (specs included). The front features photovoltaic cells for energy capture, while the back integrates junction boxes, cables, and connectors.
Solar Panel Packages
Solar panels are packaged in cardboard boxes. For streamlined logistics handling, the boxes are palletized, with additional green strapping on individual boxes for reinforcement. For large-scale shipping, boxes are secured inside containers using crossed straps to prevent movement. This multi-layer packaging ensures protection during transit, whether for short-distance warehouse transfers or long-haul international shipments of photovoltaic panels.
Efficient Logistics
JY Solar Panel provides two transportation options: sea and land. As the most commonly chosen method for the majority of orders, sea transportation is regarded as the default mode. Quotations are typically based on trade terms such as FOB, CIF, or EXW. For specific regional needs, we also offer land transportation.
