Implementation of wireless instrument for solar energy system

Solar cells are an alternative energy that is easily accessible to many households. The enhancement of solar cell research is widespread, but energy monitoring is time consuming. In order to reduce the workload and increase the ability of researchers, solar cell system measuring based on the microcontroller application and applying 2.4 GHz wireless module to transmit and receive data to a computer is considerated. Implementing Graphic User Interface (GUI) using Delphi program for recording the data in database and display them on the graphs. As the results, we measure DC voltage, DC current and AC voltage by comparing our instrument with digital multimeter. We observe that there are some errors in term of percentage such as 0.25 percent of DC voltage, 0.34 percent of DC current and 1.8 percent of AC voltage respectively. Our instrument can also send all voltages via wireless communication at transmission range of about 7 meters. The average of light intensity which provides the maximum voltage (20V) of solar energy is in between 15000 to 45000 lux during the day. This application may apply to the other applications in the solar energy systems.
