Self-cleaning solar panels

One would wish that this technology had been put on the Mars Rovers; seems pretty simple to me. Run an electric charge through the panel to electrostatically discharge the clingy dust.

Clearly this will be on the next missions to Mars. (It better be.) Also works for terrestrial solar installations, eliminating the need for barrels of Windex and armies of panel polishers.
