METHOD OF OPERATING A PHOTOVOLTAIC MODULE ARRAY

摘要

A method for operating a photovoltaic module array includes identifying when an atmospheric temperature drops below a dew point. A photovoltaic module is then positioned such that a module face is oriented at a first position substantially parallel to a ground surface permitting dew to form on the module face, the dew mixing with dust present on the module face. An angular orientation of the photovoltaic module is changed after dew formation so the module face is oriented at a second position angled away from the first position facilitating the removal of the dew entrained with the dust to be removed from the module face, thereby cleaning the module face.
