Abstract
A laser-based system and method for cleaning solar panels that have accumulate dirt or grime. The laser-based system employs methods for identifying optimum timing when the laser-based cleaning is to be performed. Otherwise, a selective cleaning will be performed on the solar panel. The method receives a combination of weather data, power output data, and solar image data to pin-point dust contours from the solar panel and removes the dust hotspots through pointed laser cleaning on accounting the tradeoff between the power consumed the by the laser and power gained from the cleaned solar panel. To achieve pin-pointed laser beam cleaning, the system adjusts the focal length of the laser beam. The method pin-points the removal of dust contours responsible for reduction in power output by analyzing weather, power output and time series images and optimally determines the region of interest to remove the dust hotspots through pointed laser cleaning.
