Photovoltaic panel clean structure design

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 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 does a photovoltaic panel cleaning device work?

The cleaning device employed a roller brush to clean the photovoltaic panel surface for non-hydrated cleaning operations and save water resources. The kinematics model of the boom mechanism was built and optimized with the end cleaning device of the upper arm structure as the research object.

How does a photovoltaic panel cleaning robot work?

( a) Three-dimensional space; ( b) Y-Z plane. In general, the hydraulic system of the photovoltaic panel cleaning robot drove the entire machine through the load sensitive pump driven by the engine so that the normal operation requirements of the entire machine’s hydraulic system in low-temperature environments could be ensured.

Can photovoltaic panels be cleaned intelligently?

During the cleaning process, there was no damage to the photovoltaic panel surface and the cleaning effect was good, which can achieve intelligent cleaning of the photovoltaic panel surface, increase work efficiency, and save labor costs.
