How to clean outdoor exposed PV surfaces?

There are three self cleaning methods viz. Electrostatic, Mechanical and coating methods which are widely being used for cleaning the outdoor exposed PV surfaces. Electrostatic method expels the dusts especially lunar dusts outside from electric curtain through electrostatic’s standing and travelling wave.

How to clean PV panel surface?

In addition, very small particles cannot be removed effectively by manual cleaning process. Therefore, researchers around the globe are promoting the self-cleaning methods, viz., electrostatic method, mechanical method and coating method for PV panel surface cleaning.

How to clean photovoltaic modules?

Traditional cleaning methods, including mechanical method, manual method, and electrostatic method, can temporarily clean photovoltaic modules. However, dust still accumulates on the surface of photovoltaic modules after a period of time.

How to clean photovoltaic panels based on CVD?

There are many methods based on CVD, and they are widely used in the self-cleaning of photovoltaic panels. But in general, such methods are not easy to control the accuracy. As a relatively simple method, the sol–gel method has low cost, few technical details, and is environmentally friendly.

Do PV panels need to be cleaned?

Therefore, proper cleaning is very much required for better performance of PV panels. As discussed in previous sections, four different methods can be applied for self cleaning of PV panels viz. mechanical method, electrostatic method, superhydrophobic coating method and superhydrophilic coating method.

How to clean dust from PV panels?

Electrostatic method also needs electrical power to operate and manual cleaning is not technically feasible at all. Nonetheless, hydrophilic and hydrophobic coatings are capable options to clean the dust from PV panels at large scale with reasonable reliability and low cost.
