Claim 11:
12. A system for cleaning a photovoltaic panel, the system comprising:
(a) at least one actuator;
(b) an inflatable wiper located on 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 debris sensor configured to detect debris on the panel;
(f) the programmable controller configured to receive a signal from the debris sensor and energize the at least one actuator when the debris is detected;
(q) a first valve associated with a first of the nozzles;
(h) a second valve associated with a second of the nozzles; and
(i) a third valve associated with a third of the nozzles;
(j) the programmable controller being configured to independently control the valves to emit the fluid from some or all of the nozzles onto the photovoltaic panel for wider or smaller focused panel cleaning.
