Analysis of the azimuth angles of a medium-scale PV system in non-ideal positions for roof application

The installation of photovoltaic (PV) panels on building roofs has seen a significant increase in recent years due to the rising cost conventional energy sources. This shift towards renewable sources been driven by urgent need mitigate effects climate change. PV applications is one most sustainable and cleanest energy, producing no greenhouse gas emissions during operation. By reducing reliance fossil fuels, use can help reduce carbon lower overall footprint buildings. In addition environmental benefits, also provide economic such as reduced costs increased property value. past, installations were mostly made direction south, but now buildings facing west, east, even north are considered for panel installations. this study, grid-connected system with an installed power 148 kWp at Konya Technical University (KTUN) campus modeled PVsyst software. systems' performance oriented different geographical directions (north, west) 30° fixed tilt angle was investigated. modeling, solar irradiation coming surfaces panels, electricity production values, ratios, their feasibility calculated. highest effective value surface obtained from found 1964.4 kWh/m². It 20.77%, 22.87%, 73.48% higher than -90°, +90°, 180° azimuth angles, respectively. concluded that generation amounts systems highly depend angle. Similarly, annual 0° 254.77 MWh. total 19.66%, 22.55%, 69.41% toward north, Performance ratio, defined ratio radiation produced, relative values between 0.843 0.862 four angles. Furthermore, analysis, Basic Payback Period (BPP) projects 6.92 years, 4.08 4.88 5.00 west directions, be suitable orientation other two feasible.
