The system includes at least one data receiver, a low-power, photovoltaic power generation and distribution system, and a unique signal detector. The data receiver receives serial digital information from a remote optical data transmitter. The data receiver serves both activation and data/control wireless datalink functions. The low-power photovoltaic power generation and distribution system includes at least one photovoltaic panel for receiving optical power from a directed beam remote optical emission source. The power generation and distribution system also includes a power accumulation and distribution portion connected to the photovoltaic panel for accumulating power generated by the photovoltaic panel for periodically and intermittently distributing accumulated power in desired quantities. The unique signal detector is connected to the data receiver and to the power accumulation and distribution portion. It is also connectable to an electrical apparatus. The periodically and intermittently distributed power enables the unique signal detector to evaluate incoming data received from the data receiver, and upon detection of the receipt of the signal qualifying as a key, thereupon issues a command to the electrical apparatus to initiate uninterrupted data communication from the data receiver.
