Dismount the Solar Panel by Removing Bolts, Screws, and Clamping Nuts: If this is not a portable solar panel and you need to move it, you should remove the bolts, screws, and clamping nuts at the mounting hardware used to fix the panel in place.
Soiling removal from PV panels by rainfall and wind is the most common soiling removal method, among which the removal of soiling particles by rainfall is usually considered to be effective . However, this soiling removal method requires a certain intensity of rainfall.
Turn Off DC and AC Disconnect Switch: As commented in the safety precautions, the first step when disconnecting solar panels is switching off circuit breakers.
Disconnect the MC4 Connector of Each Solar Panel: After everything is ready for disconnection, unplug the MC4 connector at the end of each solar panel. You can easily do this by using the disconnection/connection tool for MC4 connectors. If you lost it or did not have it at hand, you can always use a socket wrench to replace it.
Antonelli et al. developed a low-cost PV panel soiling removal robot, which can detect its own spatial position by ultrasonic sensors to adjust its travel speed and motion direction in real-time, and use a pair of alternately rotating independent spiral brushes to achieve soiling removal purposes .
The electrostatic soiling removal method offers energy saving and high efficiency, but the problems of high soiling removal cost and restricted application areas cannot be ignored. If a more economical and feasible electrostatic soiling removal device or solution can be proposed, it may significantly impact the field of PV panel soiling removal.
