Abstract The invention relates to a method (440) for detecting the type of shading (132) on a photovoltaic system (100). The method comprises at least a step of determining 5 (442) at least a first kink (124; 224; 324) in a first characteristic curve (118; 218; 318) associated with the photovoltaic system (100), at a first point in time, and at least a second kink (126; 224; 324) in a second characteristic curve (120; 218; 318) associated with the photovoltaic system (100), at a second point in time, and a step of determining (444) the type of shading on the photovoltaic system (100) so as to 10 detect shading and/or soiling, using the first kink (124; 224; 324) and the second kink (126; 224; 324). The first characteristic curve (118; 218; 318) and the second characteristic curve (120; 218; 318) represent a characteristic curve (118, 120; 218; 318) that can be determined using an electric current and voltage generated by the operation of the photovoltaic system (100). 2476330v1 m CN m~ .Uj.
