—Nowadays, due to the increasing need for electric
energy, new production areas have emerged. Solar photovoltaic
(PV) systems that convert sunlight into electricity are one of the
most popular production areas. The definite part of the needed
electricity has begun to be supplied by solar PV systems. These
systems have some disadvantages such as high cost and low
efficiency. In order to use the solar PV systems more efficiently, the
current, voltage and power values should be continuously
monitored in computer environment, and the measured values
should be analysed hourly, daily and yearly. In this study, an
electronic circuit with ATMega328P microcontroller was designed
to monitor the power generation. In order to transmit the
measured values, wireless sensor network based Xbee ZB modules
have been used due to the advantages such as low power
consumption, long battery life, reliability and low cost. An
interface and a software have been created in C# to analyze the
measured values by using tables and graphics. Also, the measured
values have been monitored on the LCD screen on the designed
circuit. The system was tested by considering both different panel
angles and ambient conditions.
