Wireless supervisory control and data acquisition system for photovoltaic installations

Performance of the photovoltaic systems suffers from inappropriate level of supervisory. Limited availability of the information about key system parameters and lack of expert knowledge of the users are the most commonly found problems. In large scale installations, due to high level of complexity, faults become more likely to happen and more difficult to be found. In extreme they may stay uncovered for long periods of time. It decreases financial performance of the PV system putting investment at risk. In presented paper novel, wireless ZigBee technology has been applied to develop robust, accurate, easy to install, low cost and autonomous sensing solution for photovoltaic supervisory systems.
