Description
The LONGi Hi-MO X10 Guardian Anti-Dust LR7-72HVHF is a high-performance solar module designed for reliable energy generation in demanding installation environments. It is available from 640W to 670W and uses LONGi’s HPBC 2.0 cell technology to deliver high efficiency and stable performance.
Its Guardian Anti-Dust frame design is engineered to reduce the impact of dust accumulation on the module, helping maintain power generation throughout the panel’s operating lifecycle. The datasheet also highlights its suitability for industrial and commercial colour steel tile roofs and small-angle installation scenarios.

Anti-Dust Design
One of the key features of this panel is its Guardian Anti-Dust design. According to the supplied datasheet, the unique frame design is intended to reduce the effect of dust accumulation and improve power-generation gain throughout the module’s lifecycle.
This makes the panel particularly suited to applications where dust accumulation and lower-angle mounting conditions need to be considered, including the industrial and commercial roof applications identified by LONGi.

One important point: this particular datasheet is for the Anti-Dust version and is not the same model as the LONGi Hi-MO X10 Guardian Anti-Glare panel. LONGi’s current product information distinguishes the different X10 variants, so I would keep “Guardian Anti-Dust” in the product title to avoid confusion.
Specifications are based on the supplied LONGi datasheet and may be subject to change by the manufacturer.
