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 .
MIT engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency. The new system uses electrostatic repulsion to cause dust particles to detach and virtually leap off the panel’s surface, without the need for water or brushes.
Understanding the impact of dust depositions on PV panels and how to mitigate them requires special attention especially in the design and development stages of PV panels, yet it would be an opportunity to study the feasibility and applicability of applying anti-reflective and self-cleaning methods on the currently installed PV systems, also .
While solar panels are easy-to-install, efficient, and simple to maintain, their power production may diminish over time if they are not properly cleaned. While nature may do most of the work for you, if dust, dirt, bird droppings, leaves, or other debris builds up on your solar panels, it can reduce their effectiveness.

6 FAQs about [What to do if there is a lot of dust on the photovoltaic panels on the roof]
How to remove dust from PV panel?
The air is hot which may reduce PV efficiency if stay for more time. It is weather related method. Effective to remove dust particles and cover all PV panel parts. Cooled or hot water could be used. Required water, pump, and controller. Sometime static system used, and other time specific vehicle used. Mechanical remove the dust using cloths.
How to clean photovoltaic panels?
At present, the PV cleaning methods are mainly natural cleaning, manual cleaning, mechanical cleaning, and self-cleaning. The improper cleaning methods will not only lead to incomplete cleaning but also destroy photovoltaic panels. In desert areas, mechanical cleaning is chosen by most of the PV plants due to the lack of water resources.
How to clean solar panels in a dusty environment?
Electrostatic cleaning Electrostatic cleaning is one of the prominent methods towards solar panel cleaning in a dusty environment. The concept has been developed with a high AC voltage which is applied to the electrodes deployed on the soiled solar panels to remove dust.
How do you remove dust from a photovoltaic module?
The main method of dust removal is manual or machine cleaning with water, but these methods have high costs and low cleaning efficiency [1, 21, 31]. It is worth noting that an improper cleaning process can cause mechanical and corrosive damage to photovoltaic modules. In areas where water is scarce, only mechanical methods can be used [79, 80].
How to clean a solar PV system?
A review of solar PV cleaning methods was made in Saravanan and Darvekar, 2018, Patil et al., 2017b. Different cleaning methods such as electrostatic cleaning, super hyperbolic coating, mechanical, microcontroller-based automatic cleaning, self-cleaning nanodomes, and various characteristics of dust particles were discussed.
How to clean a photovoltaic module?
The cleaning methods of photovoltaic modules include manual dust removal, mechanical dust removal, electrostatic dust removal, self-cleaning coating and so on. In general, the self-cleaning coating has better performance in dust removal. It requires no power or manpower, relying on its own characteristics.
