The method includes: a) cyclically measuring a current (Igiv) and a DC link voltage (U) when controlling the inverter by a MPP method (Maximum Power Point) and storing a measured current value, b) lowering the DC link voltage (U) to a value that exceeds by no more than 100% a minimum DC link voltage (Umin) admissible for operation of the inverter, c) measuring a current (Ired) with a reduced DC link voltage and comparing it with a previously stored value at a given time for the current (Igiv), d) if a prescribed threshold for a difference between the two currents (Ired, Igiv) is exceeded, a searching process for a global MPP (Maximum Power Point) is initiated, e) otherwise, operation is continued at a power maximum (MPP) with a last-stored current value for the current (Igiv)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for optimizing the yield of a partially shaded photovoltaic array","description":"A method for optimizing the yield of a photovoltaic array with an inverter is provided.
