In this study, a photovoltaic system located in on one horizontal (“UPPER”) and four different vertical surfaces (“EAST”, “WEST”, “SOUTH”, and “NORTH”) surfaces has been established to measure the solar radiation coming from different directions. All data measured in unit of volt were collected minutely during one year (April 2020 to March 2021). Photovoltaic data were calibrated in unit of W/m2 with using the data measured simultaneously from 8-48 Model B&W Pyranometer. Using the R2 and RMSE statistical methods, the solar energy data from the “UPPER” photovoltaic and the pyranometer were compared with each other and it was found that R2=95 % and RMSE=40.10 W/m2. The monthly annual total (mean) solar radiation components in the “UPPER”, “EAST”, “WEST”, “SOUTH”, and “NORTH” orientations were measured to be 4210.98 W/m2 (mean 350.92 W/m2), 1345.79 W/m2 (mean 192.26 W/m2), 2780.92 W/m2 (mean 231.74 W/m2), 3577.94 W/m2 (mean 298.16W/m2) ve 1200.93W/m2 (mean 100.08W/m2), respectively.
