Patent ID: 8323421

Claim:
An automatic cleaning system for solar panels covered by a protection panel, comprising: a cleaning device provided on the protection panel; a driving device capable of driving the cleaning device to move and comprising: a pair of slides arranged at two sides of the protection panel; two pulleys arranged on the respective slides and connected to the cleaning device to allow the cleaning device to move along the slides; a driving motor driving the pulleys to drive the cleaning device to move along the slides; a pair of secondary commutation sensors on two ends of each of the slides; and a primary commutation sensor mounted on the cleaning device, and configured to signal the driving motor to change the moving direction of the cleaning device when the cleaning device moves to the respective end of each of the slides and the primary commutation sensor aligns with the respective secondary commutation sensor; and a detection device connected with the cleaning device and the driving device, and capable of determining whether the solar panels need to be cleaned; a time controller electrically connected to the detection device, the time controller setting a regular detection time point and signaling the detection device to detect whether the solar panels needs to be cleaned if current time conforms to the regular detection time point.
