This disclosure provides a photovoltaic panel cleaning
system, relating to the field of cleaning technology. The photovoltaic panel cleaning
system includes a photovoltaic module, a cleaning module, a collection module, and a
water supply module. Multiple cleaning nozzles of the cleaning module are connected to cleaning pipelines, and the cleaning nozzles are used to spray and clean the photovoltaic panels. A
water collection tank of the collection module is located at the photovoltaic panels and is used to collect water from the photovoltaic panels; a
water collection container is used to store the water collected in the
water collection tank. A water
tower of the
water supply module is connected to the water collection container via a pumping pipeline. A first water pump is configured to
transport water from the water collection container to the water
tower via the pumping pipeline. The water
tower is connected to the cleaning pipeline via a
water supply pipeline, and a second water pump is configured to
transport water from the water tower to the cleaning pipeline via the water supply pipeline to supply water to the cleaning nozzles. The
operating voltage of the second water pump is greater than that of the first water pump, the flow rate of the second water pump is greater than that of the first water pump, and the head of the first water pump is greater than that of the second water pump, thus improving economic efficiency and
sustainability.
