Claim 5:
6. 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 tank or fan supplying pressurized air to the nozzles;
(f) the pressured air being emitted from the nozzles toward the photovoltaic panel and the inflated wiper being configured to clean the debris from the photovoltaic panel;
(g) a sensor detecting debris size and type on the photovoltaic panel; and
(h) the programmable controller being configured to change movement of the wiper and nozzles adjacent the debris based on data from the sensor.
