LR7-72HVDF-660M

The Longi Solar Hi-MO X10 Guardian (LR7-72HVDF 640-665M) series is engineered to maintain high performance where other modules typically lose efficiency – in dusty conditions, seasonal shading, and at risk of hotspots. The key difference is the anti-dust frame design, which minimizes dirt accumulation on the glass edges, thereby reducing performance degradation over time and decreasing the need for cleaning. In practice, this ensures more reliable operation during dry seasons, on sites near roads, industrial facilities, or in polluted areas.

The modules feature back-contact architecture, which enhances light capture on the front side of the cells and supports energy yield even under challenging exposure conditions. Additionally, the series emphasizes shade resistance – experiencing fewer losses from shading caused by chimneys, skylights, obstacles, and pollution. Another important feature is reduced localized heating, increasing long-term safety and operational predictability. This makes it an excellent choice for large-scale PV farms and commercial & industrial (C&I) rooftops, where high performance, serviceability, and lower energy costs over the lifetime are key priorities.
