LR7-72HVD Product Description

The LONGi LR7-72HVD 640-665M is a high-performance bifacial solar module designed for utility-scale and industrial applications. With a power output range of 640W to 665W and module efficiency up to 24.6%, this panel delivers exceptional energy yield. Featuring advanced BC-cell technology, it offers superior reliability and performance, even under harsh environmental conditions.

Designed with dual 2.0mm semi-tempered glass and a robust anodized aluminum frame, the LR7‑72HVD withstands 5400Pa front-load and 2400Pa rear-load, along with hail resistance up to 25mm at 23m/s. Its 80% bifaciality enhances rear-side energy production, making it ideal for reflective ground conditions such as snow or sand.

The LR7-72HVD 640-665M is perfect for utility-scale solar farms in high-irradiance areas such as the Middle East, Australia, and South America, where high power output and durability are essential. Its high bifaciality and rugged design also make it ideal for commercial rooftops and industrial applications in North America and Europe, where reflective ground surfaces can provide significant rear-side power generation. This module is engineered to deliver optimal performance in harsh climates, reducing overall system costs and increasing energy yield over the long term.

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

By Sea

By Land

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.
