Method and apparatus for registering conditions of performance in a photovoltaic array

摘要

Apparatus and method for registering conditions of performance in a photovoltaic array are provided. A group of neighboring photovoltaic modules may be arranged to sense a reference performance for a respective photovoltaic module of the photovoltaic array. Each of the neighboring photovoltaic modules may have a transmitter to transmit data indicative of the reference performance. The respective photovoltaic module may have a receiver to receive the data transmitted by the group of neighboring photovoltaic modules. A processor in the respective photovoltaic module may be provided to compare data indicative of its respective performance relative to the data received from the group of neighboring photovoltaic modules. The processor may be configured to register a condition of the performance of the respective photovoltaic module based on a result of the data comparison.
