NOVELTY - The method involves selecting a power transfer objective e.g. target. Values are assigned for multiple parameters related to the power transfer objective. Intelligent nodes (100) are connected to a combination of serial and parallel electrical circuits selected according to the power transfer objective and the values of the parameters. An amount of change in the parameters related to the power transfer objective is measured. Determination is made whether the measured amount of change in the parameters correlates to a change of photovoltaic array configuration.    USE - Method for configuring electrical connection between intelligent nodes i.e. photovoltaic panels, in a photovoltaic array for transferring electrical power from the photovoltaic array to an electrical load in a solar photovoltaic power generation system.    ADVANTAGE - The method enables rapidly adjusting the configuration of serial and parallel electrical connections between photovoltaic panels in the photovoltaic array to supply electric power to an electrical load according to the objectives for power transfer. The method is economically scalable to very large photovoltaic arrays such as utility-scale photovoltaic arrays. The method enables efficiently transferring electrical power from the photovoltaic array to the electrical load connected to the photovoltaic array by configuring connections between the photovoltaic panels in the photovoltaic array in selectable combinations of serial and parallel electrical circuits. The method allows providing economical and efficient control of power transfer from the photovoltaic arrays of fewer than hundred photovoltaic panels to utility-scale photovoltaic arrays with hundreds of thousands of photovoltaic panels. The method enables rapid reconfiguration of serial and parallel electrical connections for adapting the photovoltaic array to changes in operating conditions. The data sent to individual photovoltaic panels can travel over relatively high speed data pathways, thus reducing time needed for reconfiguring the array from few minutes to few seconds. The array can be reconfigured from one combination of serial and parallel connections to another combination of connections without disconnecting and reconnecting electrical cables.
