Design of Automatic Control for Surface Cleaning Systems of Photovoltaic Panel

摘要

The paper presents experimentally design of a cleaning system for the surface of photovoltaic panel using wiper control mechanism utilizing ATmega16 microcontroller. The proposed cleaning system operates by spraying an amount of water on the PV panel surface and then actuating the wiper using a DC motor. Two limit switches are used to sense the wiper position at the edge of the PV panel. In the experimental test, an amount of dust is deployed on the PV panel surface to test the control power performance. The proposed design is high effectively used to bring back to the initial efficiency output of the PV panel over the efficiency of dirty panel. The wiper can be managed to work periodically for example five times in a day or can be manually activated using remote control mechanism. The power consumption performances of the proposed system are only about 0.79% and 8.94% under standby and operation conditions, respectively. The low power consumption makes this cleaning system is feasible for further product development.
