A research team from the Chinese Academy of Sciences recently designed a global dust prediction modeling tool called iDust that develops and improves upon limitations in similar existing programs.
Their study, published in the Journal of Advances in Modeling Earth Systems, aimed to better inform the use of solar energy in areas with high levels of dust, since dust storms tend to accumulate on solar panels and lower their effectiveness.
In particular, regions like Australia, the Middle East, the Sahara, the American Dust Belt, and Patagonia could all benefit from solar panels that perform well despite higher atmospheric dust concentrations.
To account for dust accumulation when developing iDust, the researchers integrated dust processes into the forecasting model's dynamical core, using only about one-eighth additional computing power to "[outperform] its counterparts in dust storm forecasting intensity and timing."
In addition to tracking storms, iDust can generate 10-day dust forecasts with just six hours of computing.
As a test, the team monitored an extreme dust storm in the Bayannur region of China in mid-April, according to Tech Xplore.
"iDust's development and successful implementation marks a significant advancement in dust forecasting, delivering accurate, efficient, and high-resolution dust predictions in real-time across various temporal and spatial scales," the researchers wrote.
Ordinarily, it is difficult to account for dust accumulation on solar panels. Homeowners and engineers, as a result, believe solar panels are yielding more energy output than they actually are — an overestimation of up to 25%, per Tech Xplore.
By incorporating dust metrics into solar panel technology, the researchers hope to provide more accurate energy calculations to facilitate the mainstream integration of solar power globally. Namely, the team expects iDust to assist solar farms and power grid operators in preparing for dust storms by adjusting their production accordingly.
"As the world transitions towards renewable energy," the study concluded, "accurate and timely dust forecasts will be crucial for optimizing the design, maintenance, and operation of solar and wind energy infrastructure in dust-prone regions."
