Solar tracker cleaning system and method

摘要

A solar tracker waterless cleaning system for cleaning solar panels of solar trackers in at least one solar tracker row, each solar tracker having a length and a width and being able to be positioned at a pre-determined angle, the cleaning system including at least one waterless cleaning apparatus operable to clean a panel surface of the solar tracker row without using water, at least two rails positioned horizontally parallel to the solar tracker row, a support frame for supporting the cleaning apparatus and a controller coupled with the cleaning apparatus and with the support frame for moving the cleaning apparatus in the width direction and the length direction of the solar tracker row, the support frame moving over the rails and moving the cleaning apparatus in a width direction and a length direction of the solar tracker row while maintaining a pre-determined angle in the width direction of the solar trackers.

1. A solar tracker waterless cleaning system for cleaning solar panels of solar trackers in at least one solar tracker row, said solar tracker row comprising a plurality of solar trackers, each said solar tracker having a length and a width and being able to be positioned at a pre-determined angle, said waterless cleaning system comprising:
at least one waterless cleaning apparatus operable to clean a surface of solar panels of said at least one solar tracker row without using water; at least two rails positioned horizontally parallel to said solar tracker row; a support frame for supporting said at least one waterless cleaning apparatus, said support frame moving over said at least two rails and moving said at least one waterless cleaning apparatus in a width direction and a length direction of said at least one solar tracker row while maintaining a pre-determined angle in said width direction of said solar trackers; a controller coupled with said at least one waterless cleaning apparatus and with said support frame for moving said at least one waterless cleaning apparatus in said width direction and said length direction of said at least one solar tracker row, thereby causing said at least one waterless cleaning apparatus to clean said surface of said solar panels while moving downwards in said width direction of said solar trackers; a plurality of rail segments; and a plurality of rail switching points, wherein said at least one waterless cleaning apparatus comprises at least one air stream generating apparatus for creating a directional air stream in said width direction of said at least one solar tracker row, said directional air stream pushing dust particles from said surface of said solar panels downwards and off said solar panels of said solar trackers; said at least one air stream generating apparatus comprising a plurality of flexible microfiber fins that move in said direction of said directional air stream and touch said surface of said solar panels to enhance a cleaning of said surface of said solar panels without using water; wherein consecutive ones of said plurality of rail segments are respectfully coupled with consecutive ones of said at least two rails; wherein said plurality of rail switching points are coupled between at least two of said plurality of rail segments and said at least two rails; and wherein said plurality of rail segments and said plurality of rail switching points enable said system to clean said solar panels of solar trackers in at least two solar tracker rows.
