Show series description

The Longi Solar Hi-MO X10 Guardian (Anti-Glare) LR7-54HVH 480~500M series is designed for locations where not only energy yield matters, but also the surrounding comfort and safety. The key difference is the Anti-Glare surface – a special textured glass structure that minimizes local glare spots, making the installation more suitable near roads, airports, residential neighborhoods, and public facilities.

In practice, this means less risk of complaints about reflections and greater design freedom, without compromising efficiency. The manufacturer emphasizes high transparency of the front layer, which helps maintain light power and absorption comparable to conventional modules. Additionally, the solution is non-coated and dust-resistant, supporting stable performance and minimizing uneven soiling issues over the long term.

This is an excellent choice for demanding rooftops and commercial installations where non-glare aesthetics, predictable energy yields, and long-term durability in real operating conditions are crucial.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
