Remote monitoring of solar panel data over dc power line and its effects on efficiency

The production of energy derived from the sun and wind varies according to time and external factors. In order to produce stable energy, the generators need to be continuously monitored, managed and run in harmony with the city grid. Today, intelligent energy systems have been developed to use solar and wind energy production plants as integrated. Thanks to these systems, production levels and yields of resources can be monitored and managed when necessary. In intelligent energy systems, the Power Line Communication (PLC) method is preferred because of the use of the existing energy line and the lack of equipment costs. In this study, parameters such as ambient temperature, panel temperature, humidity, light ratio, panel current and panel voltage were obtained at certain time intervals and became serial information. The data were transferred to the computer environment using the DC power line (Power Line Communication, PLC) of the current photovoltaic panel with the FSK modulated transmitter and receiver, and the data was recorded. In this study ,the PW panel power line has been used for communication. On the receiving side, the data received from the FSK demodulator was read by the microcontroller and the graphics of the panel parameters were created with Python-based writing software. The data obtained were analyzed and the factors affecting energy production were investigated.
