The Longi Solar LR4-72 HBD 445W Bifacial solar panel is a high-quality 445W monocrystalline panel that uses Bifacial technology for double solar energy collection. Due to its special design with bifacial energy absorption, this panel can generate more electrical energy, even in limited light conditions. Designed for large commercial and industrial solar systems, it provides high performance and reliability under heavy loads. Increased resistance to weather conditions and mechanical damage makes the panel an ideal choice for long-term use in harsh environments.
This model is ideal for industrial and commercial applications. High efficiency, reliability, and durability thanks to top-quality design and materials.
Main advantages:
445 W power for high performance
Bifacial technology for double energy collection
High efficiency, up to 20.2%
Resistant to weather conditions and mechanical damage
Easy integration into existing solar systems
High IP68 protection class ensures reliability
Suitable for use in industrial and commercial solar installations
Application:
Commercial solar systems: Use in large shopping centers, office buildings, business parks to ensure stable electricity generation.
Industrial installations: Integration into manufacturing plants, factories, warehouses and other high energy consumption facilities that require powerful and reliable generation.
Large-scale solar power plants: Use in ground-mounted solar farms to generate electricity on an industrial scale.
Systems with increased reliability requirements: Facilities with extreme climatic conditions (high humidity, heat, severe frosts), where resistance to mechanical stress and weather effects is required.
Projects with limited space: Thanks to Bifacial technology, the panel allows you to increase the generation from the same area (reflection from surfaces is involved), which is important for roof and limited areas.
Long-term energy solutions: Suitable for investment projects where the efficiency, durability, and reliability of equipment for decades are important.
