Electricity has an essential place in the life of humanity with the rapidly developing technology. It has been seen that the use of fossil fuels for electrical energy production harms the environment. People have turned to renewable energy sources that have the least damage to the environment in order to meet the needs of electricity. The systems that produce electricity from solar (photovoltaic systems) are the most preferred renewable energy sources. Because there is no the payment of fees to the raw energy sources and staff expenses are little during operation. Also the low maintenance costs due to the small parts are among the advantages. In this study, monocrystallinesolar panel installation was conducted in Afyonkarahisar. Solar panels have been placed at an angle of approximately 45o. The solar panel production data (voltage and power) were instantly monitored from the PC and recorded to Access database at 10 second intervals by the help of micro-controller control board and C# software. Energy production of the solar panels is determined using the one-year data.
