Claim 13:
14. A system for cleaning a photovoltaic panel, the system comprising:
(a) at least one actuator;
(b) an inflatable wiper spanning across the photovoltaic panel and being configured to move along the photovoltaic panel in response to energization of the at least one actuator, the inflatable wiper contacting against the photovoltaic panel when the inflatable wiper is inflated and moving;
(c) nozzles being configured to move along the photovoltaic panel in response to energization of the at least one actuator;
(d) a programmable controller configured to cause fluid to be sent to the nozzles, inflate the wiper and adjust speed of panel-cleaning;
(e) a remote mobile transmitter in communication with the programmable controller and configured to send a cleaning command to the controller;
(f) a fluid supply, the controller operably energizing the at least one actuator and the fluid supply; and
(G) the at least one actuator comprising multiple air-driven pistons movable in a linear direction substantially perpendicular to a direction of elongation of the wiper, the pistons being located adjacent to opposite sides of the photovoltaic panel.
