Measurement and Evaluation of Solar Panel Data Via DC Power Line

Today, it is important to monitor the data first of all in order to increase the efficiency of solar panels. In this study, parameters affecting the efficiency of photovoltaic panels, such as ambient temperature, panel temperature, humidity, light ratio, panel current, panel voltage were measured at certain time intervals. The data was then transferred to the computer via the PV panel (Power Line Communication, PLC) using the existing photovoltaic panel DC power line with the FSK modulator-demodulator, which was converted into a serial information package and designed, and the data was recorded. Here the panel data is collected entirely via its own energy cable without the use of any lines or wireless units. With Python-based software, graphs of panel parameters were created, the data obtained were analyzed and the factors affecting energy production were examined.
