Robots clean solar panels in Israel without using water

At Ketura Sun, a large commercial solar field in Israel, the solar panels are being cleaned in a unique way: by robots. That's not the most unique part. These robots don't use any water in the cleaning process, making them a great match for the Negev desert where the solar plant is located. Even better, the robots could go a long way toward making solar power plants less dependent on water.

According to Gizmag, the Ecoppia E4 robots are "mounted on a frame that moves laterally along the panels and the robots themselves move up and down the panels. They use a rotating brush made up of soft microfiber in conjunction with air blowers to remove what Ecoppia says is 99 percent of dust build-up." No water required.

Other solar panel cleaning robots have been developed, even some that don't use water, but those are not being commercially used yet.

Keeping solar panels clean is a major necessity because dust covered panels don't produce as much energy (up to 35 percent less), but non-automated processes require a lot of manpower, time and money. The robots make it so that the panels are automatically cleaned nightly and are always operating at maximum output.
