Herringbone photovoltaic panel cleaning

Which cleaning technique is best for solar PV panels?

The TOPSIS method is employed to compare the cleaning techniques and rank them from most favored to least favored. Manual cleaning of the PV panels is the highest ranked cleaning technique according to the TOPSIS ranking. The efficiency and power output of photovoltaic (PV) panels are vital to the solar PV plant.

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.

Could robotic cleaning be a solution for PV systems?

Mechanical cleaning such as autonomous robots 19, 20, 21 could be a solution for cleaning of PV systems because it has several advantages such as quick response and high reliability in addition to solving the problems of labor. Nevertheless, the initial cost is high in case of robotic cleaning due to the use of various hardware.

Are photovoltaic panels soiled?

Provided by the Springer Nature SharedIt content-sharing initiative Photovoltaic (PV) panels are similar in many aspects to the leaves of trees, both are standing in the Sun to capture the sunlight, however, PV panels get soiled especially in desert areas, while the leaves remain clean to a very good extent.

Which surface treatment is suitable for preparing photovoltaic self-cleaning surfaces?

CVD-based surface treatment is suitable for preparing photovoltaic self-cleaning surfaces. These methods prepare self-cleaning surfaces by reacting gaseous substances with hot surfaces and depositing them on the surface. They are efficient but difficult to control accuracy.
