Waterless cleaning system and method for solar trackers using an autonomous robot
First Claim
1. A solar tracker waterless cleaning system for cleaning solar panels of a solar tracker under varying wind conditions, said solar tracker being able to be positioned at a pre-determined angle, said solar tracker waterless cleaning system comprising:
- a docking station, coupled with an edge of said solar tracker;
an autonomous robotic cleaner (ARC); and
a master controller, for receiving and transmitting data to and from said solar tracker and said ARC,said ARC comprising;
at least one rechargeable power source;
at least one cleaning cylinder, for cleaning dirt off of a surface of said solar tracker without water; and
a controller, for controlling a cleaning process of said ARC and for transmitting and receiving signals to and from said ARC,said controller comprising an at least 6-axis motion sensor, for determining an angle of said solar tracker and a heading of said ARC;
said docking station comprising;
at least one electrical connector, for recharging said rechargeable power source;
a plurality of locking bars, coupled with said docking station, for protecting said ARC during said varying wind conditions;
a plurality of anchoring elements; and
at least two physical barriers, a first one of said at least two physical barriers positioned on a first side of said docking station and a second one of said at least two physical barriers positioned on a second side of said docking station, for preventing said ARC from falling off of said docking station,each one of said plurality of anchoring elements comprising a plurality of supporting elements,wherein said at least one electrical connector is coupled between at least two of said plurality of supporting elements;
wherein said ARC can anchor in said docking station;
wherein said ARC cleans said solar tracker when said solar tracker is positioned at said pre-determined angle;
wherein said pre-determined angle is between −
10 to +10 degrees from a horizontal angle of zero degrees;
wherein said at least 6-axis motion sensor is used for navigating said ARC over said surface of said solar tracker;
wherein said master controller determines an average wind speed and provides a clean command to said ARC if said average wind speed is below a predetermined threshold;
wherein said at least one electrical connector also anchors said ARC; and
wherein said plurality of supporting elements are rigidly coupled with a docking surface of said docking station.
