But the process never ends (it's been running for 24 hours even though I tried it on a small area). I couldn't understand what the problem was.</P><P>Projections of my DEM and my Data Frame are WGS-1984. I used to earthexplorer USGS.<BR />Is there a possibility that there is an error in the Dem data I downloaded?&nbsp;</P> Sat, 01 Apr 2023 07:58:31 GMT https://community.esri.com/t5/geoprocessing-questions/what-s-wrong-with-my-solar-radiation-process/m-p/1274370#M26799 BURAKAKDAG 2023-04-01T07:58:31Z https://community.esri.com/t5/geoprocessing-questions/what-s-wrong-with-my-solar-radiation-process/m-p/1274375#M26800 <P>Did you see</P><P><A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/area-solar-radiation.htm" target="_blank">Area Solar Radiation (Spatial Analyst)—ArcGIS Pro | Documentation</A></P><P><EM>Calculating insolation can be very time consuming, where the calculations for a large digital elevation model (DEM) can take several hours, and for a very large DEM, even days.
