Özet

In photovoltaic (FV) systems, data collection units are used to monitor the system's stability and performance. Monitoring and analyzing instantaneous changes of the electrical signals collected from the panel helps detection of the errors easily. This is accomplished by transferring data collected from panels by cables. There are some technical and cost limitations of this method. Moreover, considering the high temperature, humidity, rain, snow and harsh environmental conditions, wireless data transfer provides a big advantage over the wired transfer. In this study, an online software system has been developed for sending the data such as voltage, current, radiation, temperature, and humidity obtained from an installed 1000W PV system via the Bluetooth. A website has been designed for monitoring the data online. Software compatible with both Bluetooth 2.1 and 4.0 standards, which runs on Raspberry Pi, collects the electrical measurement data of PV panels that was placed at various locations. The web interface provides monitoring all data received by the server instantaneously and the stored data can be analyzed easily.
