The work in Kazem et al. (2020) discusses the impact of dust accumulation on PV panels followed by analyzing different cleaning methods for PV panels. The cleaning methods discussed include the following: (1) forced air flow of air conditioning system, (2) natural cleaning using rain and wind, (3) water cleaning, (4) manual cleaning, (5 .
Dust on solar panels reduces their output significantly, so they need to be kept clean. But what’s the best way to do that? Scientists at the Massachusetts Institute of Technology (MIT) say.
Ultimately, a detailed strategy for dust prevention in PV panels is proposed, involving real-time monitoring, assessment of dust deposition, mathematical modeling for predicting performance losses, and informed decision-making regarding optimal cleaning measures to enhance panel efficiency.
Kazem et al. (2014b) studied experimentally the effect of 3 different types of dust (sand, ash, and red soil) on the performance of PV panels (monocrystalline, multicrystalline, and Amorphous-Silicon). The results indicated that carbonaceous fly-ash has the largest effect compared to the other two types of dust.

What is the best way to remove dust from PV panels?
In some cases, nature may be the most functional and cost-effective dust-removal solution. Various research around the world has documented that the natural result of snow or rain cleaning. Rain sweeps away the dust and soiling in majority of situations, and PV panels performances are usually recovered to near-original levels (Sarver et al., 2013).
Does dust affect the performance of PV panels and cleaning methods?
Many researchers have reviewed the effects of dust on the performance of PV panels and cleaning methods, but their coverage is narrow and lacks more in-depth summarization, comparison, and critique of key quantitative results.
How do you clean dust off solar panels?
One of the most common ways to clean dust off solar panels is to spray them with water. But that’s a huge waste of water, especially in desert settings, where there are a lot of solar farms. The MIT scientists note in their new study, which is published in Science Advances:
Does dust affect solar PV system efficiency?
Zaihidee et al. (2016) indicated that the level of PV system efficiency loss relies mainly on the accumulation density; the researchers noted that a 20 g/m 2 accumulation of dust on a solar PV panel lowers the I sc, V oc, and overall efficiency by 2%–6%, 15%–21%, and 15%–35%, respectively.
