Assisting device for assisting maintenance of solar power plant, has processing unit controlled by control unit, and individual modules for varying electrical parameter and analyzing changes in measured parameter

摘要

The device has individual modules (20) for varying an electrical parameter i.e. current intensity, at electrical outputs of photovoltaic solar panels (4) of a photovoltaic system (1). A monitoring module (6) is arranged common to the photovoltaic panels, and a control unit (61) independently controls the individual modules. A measuring unit (62) measures the electric parameter at a point of a collection circuit (3), and a processing unit (63) determines a defective photovoltaic panel and is controlled by the control unit. The individual modules analyze changes in the measured parameter. An independent claim is also included for a method for assisting maintenance of a photovoltaic system.
