The Chinese company LONGi is one of the world’s leading providers of photovoltaic solutions. With the LR7-54HVBB solar module, LONGi offers a high-performance module with a rated power of 480 Wp. It is based on LONGi’s proprietary HPBC 2.0 technology, which enables a high efficiency of over 23.8%. This allows more electricity to be generated from the same area – a key advantage where space is limited.
Thanks to rear-mounted contacts, the back-contact technology enables efficient use of the entire cell surface. With no visible busbars and combined with the full-black design, this creates a uniform and modern appearance. The low-glare design also makes the module suitable for environments where a discreet appearance is desired, such as high-end residential and commercial buildings.
The LR7-54HVBB features integrated anti-shading functions and additional protection against localised overheating (hot spots). These features increase operational safety and contribute to a longer module lifespan. In addition, the module has a low carbon footprint throughout its entire life cycle, supporting its use in sustainable energy concepts. LONGi underlines the reliability of the LR7-54HVBB with a 30-year warranty – a clear commitment to quality and durability.
