Fotovoltaik hücrelerde veri toplama sistemleri (DAQ'lar)

Solar Energy is one of the most useful resources of renewable energy. The world is committed to increasing the use of renewable energies capable of replacing fossil fuels, diversifying energy sources, and reducing carbon dioxide emissions. Technological developments, increased energy demand, reduced fuel supplies, and environmental pollution are factors that have intensified the search for new solutions for energy production. By using data acquisition and applying computer algorithms, it is possible to efficiently and effectively harness this energy system. In order to analyze the performance of photovoltaic systems, real-time instrumentation is used and made accessible on a personal computer. This thesis presents a cost-effective technique necessary for real-time instrumentation of PV panels to enable the measurement and records of various characteristics of panels including the voltage, current, and power using virtual instruments. The values are plotted in a Microsoft Excel Streamer via PLX-DAQ data acquisition Excel Macro. This facilitates the exchange of information between the ATMega328 microcontroller of the Arduino UNO board and the UART bus port of the personal computer. Therefore, the characteristics such as I-V and P-V which are in real-time conditions can be acquired and plotted on an Excel spreadsheet without requiring reprogramming of the microcontroller. This work is found to present several beneficial solutions as compared to conventional solutions. One of which is the presentation of real-time data in graphical form.
