Abstract
A system and method for cleaning a collector surface of a solar collector. The system includes a first liquid-dispensing unit configured to deliver a first spray of liquid to the collector surface. The system also includes a brush element having a longitudinal side oriented along a first direction and disposed adjacent to the first liquid-dispensing unit. A first squeegee element is oriented along the first direction and adjacent to the brush element. The first squeegee element, the brush element, and the first liquid-dispensing unit define a first cleaning area. A second squeegee element is oriented along the first direction and separated from the first squeegee element by a gap to define a second cleaning area. The system also includes a second liquid-dispensing unit configured to deliver a second spray of liquid to the second cleaning area located between the first and second squeegees.
