LONGi Launches BC Module For Desert Applications

With growing demand for desert application-specific PV modules, leading vertically integrated PV manufacturer LONGi launched its Hi-MO X10 series anti-dust module, Anti-Dust Pro, at the recent World Future Energy Summit (WFES) 2026. 

As its name indicates, the product exhibits anti-dust properties, achieved through a ‘dust-free’ front glass and frames with no front covers along the short-side edges of the PV glass. With an ultra-thin nanometer-scale ceramic coating, the glass exhibits hydrophobicity that prevents water from spreading across the surface, instead forming droplets and rolling off easily. In addition, it creates an anti-static surface that prevents static charge buildup, minimizing dust adhesion to the glass. According to the company, with these 2 characteristics, even a small drop of rainwater can easily wash away the loosely deposited dust and dirt along the short-side edge (closer to the ground) of portrait-oriented PV modules. Unlike conventional PV modules, its reduced soiling effect allows additional light to reach the active cell areas, contributing to a higher annual energy yield of 1.5% to 3%, the company claims. In addition to rainwater-based self-cleaning, the anti-soiling property also optimizes operating expenditure (OpEx) by reducing cleaning frequency to up to 40% less, or 2 times a year. This also contributes to sustainable operational practices, albeit passively. 

Apart from improved power-generation metrics, nanocoating also enhances mechanical durability, helping protect the glass against potential micro-scratches from sand and cleaning tools. 

This module, equipped with antimony-doped wafer (TaiRay) based back contact (BC) half-cells, is rated for a maximum power output of 680 W. LONGi, however, didn’t disclose the efficiency or commercialization details in its press release.
