NOVELTY - The device (400) has an electrically driven vibration transducer (406) which induces vibrations in a solid media (402). The electrically driven vibration transducers and an external vibration receiver are the components of an electrical circuit that is in electrical contact with a photovoltaic solar panel (102). The solid media transmits the vibrations to the vibration receiver. The receiver converts the vibration into an electrical signal. The sonic or ultrasonic vibrations transmit and receive the data. The photovoltaic power cables of the media are provided with snap connectors.    USE - Vibration mediated data communication device for mesh-networked local photovoltaic solar panel. Can also be used in non-photovoltaic applications such as electricity poles and towers, communication applications.    ADVANTAGE - By using power optimizer circuit, the proper adjustment for individual router is computed and the adjustment sensor data packets are send to the individual router device so that optimization of overall power output of the photovoltaic solar array can be achieved efficiently without the electrical and radio interferences so that safety can be ensured at low cost. By using local power optimization units of a solar panel array, coordination between the individual power optimization units can be enhanced. The response of the solid media vibration channel is estimated so as to improve the communication performance. Since each vibration mediation communication node functions as independent router, the breakdown of the solar panel can be avoided.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of optimizing overall power output of photovoltaic solar array.
