How can a photovoltaic system be cleaned?

Cleaning with special PV cleaning devices guarantees consistently high yields and a longer service life of the photovoltaic system. With the innovative cleaning solution SunBrush® mobil, your photovoltaic systems can be cleaned conveniently in passing.

How to clean PV panels?

The cleaning processing of PV panels by the designed robot consists of three steps: start to run the system, then action to move the trolley down, and move the brushes to clean the PV panel surface in the meantime.

How many solar PV panels are used in a cleaning robot?

Two solar PV panels are connected in series, the capacity of each panel is 335 W, and their total is 670 W, to test, operate, and evaluate the proposed cleaning robot. The specifications of the solar PV panel used are shown in Table 1.

How do you clean a solar panel?

However, solar power is a concern globally, as panel cleaning incurs costs, including environmental consequences, regardless of the location. The usual approach consists of using pressure washers or tractors with hydraulic brushes to clean the surfaces.

How effective is a solar panel cleaning robot?

After carrying out the cleaning process, the efficiency of the solar panels for power production increased to reach 98.91, 92.96, and 62.11 for simple, moderate, and intense dust PV panels, respectively. Thus, it can be seen that this robot combined with a color monitoring system will be more effective in solar PV panel systems on a large scale.

How long does it take to clean solar panels?

As a result of the great variance in the results of the power produced by the different solar panels in the degree of surface cleanliness, the cleaning robot was operated to clean the dust-density gradient solar panels, where the time required to carry out one cleaning round was from 10 seconds at a speed of 300 rpm = ~ (0.7 m/s).
