System for controlling energy consumption of building, generates control signal based on ratio of current output power of photovoltaic system and current power consumption of power consumers in building

摘要

The system has a measuring unit (11a) that determines current output power of a photovoltaic system (10a). A measuring unit (21) determines current power consumption of power consumers in building (1). A control device (30) receives output power and current power consumption values from the measuring units and generates a control signal based on the ratio of current output power and current power consumption values.
