Wireless sensor network for photovoltaic modules monitoring

A wireless system for photovoltaic plant monitoring is presented. The system detects faults in each individual photovoltaic module connecting several electronic circuits in parallel to each module and connecting them with a Wireless Sensor Network to a central wireless control unit. The general system and a first prototype of the electronic circuit for a single photovoltaic module are presented. The system was designed in terms of easy implementation and low cost, without any extra sensors.
