Patent ID: 8756739

Claim:
A solar power surface-cleaner system, comprising: a motor; electronics including a first cleaning head, the first cleaning head including: a first positive conductor and a first negative conductor; a second positive conductor and a second negative conductor, wherein the second positive conductor and the second negative conductor are arranged between the first positive conductor and the first negative conductor; a first high-voltage supply connected to the first positive conductor and to the first negative conductor; a second high-voltage supply connected to the second positive conductor and to the second negative conductor; and a controller configured to actuate the motor to move the first cleaning head with respect to the solar power surface, to activate the first high-voltage supply to apply a first multiphase high-voltage waveform to the first positive conductor and to the first negative conductor using a first duty cycle, and to activate the second high-voltage supply to apply a second multiphase high-voltage waveform to the second positive conductor and to the second negative conductor using a second duty cycle, wherein the first duty cycle is out of phase with the second duty cycle; and a power generator including at least one photovoltaic cell, wherein the power generator is configured to: power the motor to move the first cleaning head with respect to a solar power surface; power the controller; and power the first and second high-voltage supplies to generate a first electrostatic cleaning field around the first cleaning head to move particulates in the same direction as the first cleaning head; wherein moving the first cleaning head with respect to the solar power surface while the first electrostatic cleaning field is generated moves particulates off of the solar power surface.
