LR8-66HYD Product Description
The LONGi LR8-66HYD 635-670M is a state-of-the-art bifacial solar module designed for large-scale utility installations requiring maximum energy yield and long-term reliability. With output ranging from 635W to 670W and up to 24.8% module efficiency, this module utilizes BC-cell technology for enhanced performance and durability in challenging environments.
Featuring dual 2.0mm tempered glass and an anodized aluminum frame, the LR8-66HYD is built to withstand 5400Pa front-load and 2400Pa rear-load, ensuring robustness in high-wind, snow-prone, and hail-prone regions. The module’s 80% bifaciality increases rear-side energy generation, making it ideal for areas with high albedo surfaces such as snow or sand.
The LR8-66HYD 635-670M is the perfect solution for utility-scale solar farms in high-irradiance and dust-prone regions such as the Middle East and Australia, where its bifacial design and durable build offer reliable energy production. Its high power output and robust construction also make it ideal for installations in Southeast Asia, South America, and Europe, where reflective surfaces or varying climates can significantly boost rear-side energy generation. With its 1500V compatibility and high efficiency, the LR8-66HYD is ideal for reducing BOS costs in North American and European utility and commercial projects.

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.
