solar radiation error

[mariaRodrigues]

I have tried to calculate solar radiation (whole year with monthly interval) for Portugal from an ESRI grid (27m DEM). It seems to work, however it takes much more than a week and in the meantime there was an energy failure. I use ArcToolbox/Spatial Analyst Tools/Area Solar Radiation.

I have cut the dem so as to have only the south of Portugal in the hope that the processing would be faster.
However, ArcGIs 10 crashes after a few minutes and I get the error:
"Background processing has encountered a serious error and is unable to continue. Contact ESRI".
I have also tried in Arcgis 9.2 and I get the same message.

It simply seems not to like the cut dem.
Could anyone help?

Hi,

I came across the same problem but with ArcMap 10.0. Solar Radiation tool worked at first, then it didn't for a couple of days and I tried many possible solutions before contacting the support.

The support told me to:

1. Add servicepack 5 for the ArcGIS 10.0
2. Remove background processing, doing this in ArcMap > GEOPROCESSING - GEOPROCESSING OPTIONS - and then disable BACKGROUND PROCESSES.
