Modeling of a 10 kw rooftop photovoltaic system and comparison with real production data

In this thesis, a photovoltaic system with an installed power of 10 kWp, which was built on the roof of a school cafeteria in Gümüşhacıköy district of Amasya, was modeled using the PVsyst V7.1.0 DEMO software and PVSOL Premium 2022 DEMO software. The real-life data of the system and the production data calculated from the software used were compared. While the actual total electricity production data of this photovoltaic system for 2021 was determined as 12 473 kWh, this value was obtained as 12 912 kWh using PVsyst software and 13 556 kWh using PVSOL software. While there was a 3.40% difference between the estimated production value and the actual production value with the PVsyst software, it was determined that there was a 7.99% difference between the estimated production value and the actual production value of the system as a result of the simulation made with PVSOL. In addition, the analysis results of the system using the PVSOL Premium 2022 DEMO software were compared with the results obtained from the PVsyst V7.1.0 DEMO software. From the production estimates made with two different simulation software, it was seen that the PVsyst software gave results closer to the real-life data. In both software, the production value is more than the real electricity produced by the photovoltaic system in 2021. In addition, the reasons for the differences between the results obtained from the software and the real-life data are discussed.
