A new cleaning method could remove dust on solar installations in water-limited regions, improving overall efficiency

Solar power is expected to reach 10 percent of global power generation by the year 2030, and much of that is likely to be located in desert areas, where sunlight is abundant. But the accumulation of dust on solar panels or mirrors is already a significant issue—it can reduce the output of photovoltaic panels by as much as 30 percent in just one month—so regular cleaning is essential for such installations.
