Abstract: An electronic control system ( 1 ) to control exploitation of electrical power produced by a household photovoltaic system ( 2 ) to electrically power remotely electronically-controllable electric household appliances ( 8 ). The household photovoltaic system ( 2 ) is electrically connected to a public electrical power mains ( 3 ) and to a household electric system ( 4 ) via an electronic electrical power meter ( 5 ) configured to measure the electrical power produced by the household photovoltaic system ( 2 ) and the electrical power absorbed from or supplied to the public electrical power mains ( 3 ) as a result of an electrical power underproduction or overproduction of the household photovoltaic system ( 2 ) compared to the electric power consumption of the household electric system ( 4 ). The electronic control system ( 1 ) comprises an electronic control unit ( 14 ) provided with a user programming interface ( 15 ) and configured to communicate with the electronic electrical power meter ( 5 ) to determine an excess of electrical power produced by the photovoltaic system ( 2 ) over the electric power consumption of the household electric system ( 4 ), and with the electric household appliances ( 8 ) to remotely control operation thereof based on the excess of electrical power produced by the photovoltaic system ( 2 ) over the electric power consumption of the household electric system ( 4 ), on programmed operation priorities, and on programmed automatic operating modes. The electronic control unit ( 14 ) is further configured to store a plurality of user-selectable operating modes of the electric household appliances ( 8 ) and to allow the following programming of the operation of the electronic control unit ( 14 ) to be performed via the programming user interface ( 15 ): 
- inputting a list of electric household appliances ( 8 ) to be remotely controlled, and information indicative of the electrical and operating characteristics of the electric household appliances ( 8 ) comprising electric power consumption and durations of the operating cycles; 
- programming operation priorities of the electronic household appliance ( 8 ) to define a timeline of operation of electric household appliances ( 8 ), 
- programming a specific automatic operating mode for each of the electric household appliances ( 8 ) and selectable from: 
- one or different first automatic operating modes aimed at prioritizing completion of the operating cycles of the electric household appliances ( 8 ) within programmable completion times with respect to the exploitation of electrical power produced by the household photovoltaic system ( 2 ) for the execution of the operating cycles of the electric household appliances ( 8 ), and 
- one or different second automatic operating modes aimed at prioritizing exploitation of the electrical power produced by the household photovoltaic system ( 2 ) for the execution of the operating cycles of the electric household appliances ( 8 ) with respect to the completion of the operating cycles of the electric household appliances ( 8 ) within programmable completion times.
