Solar Radiation output

I just finished running the area solar radiation tool for a full year on a 10m DEM.  Looks good, but I'm having trouble understanding the format of the results.  The main output is displayed as a 3-band raster (RBG).  I can change this to display stretched format and thereby get a single value for each pixel.  When I examine the file though (expand in the catalog), I find that it contains 12 individual bands, numbered sequentially. 

Web Help tells me:
"the default output format is an ESRI GRID stack containing multiple bands that correspond to the radiation or duration values for each time interval"

Questions:
1) What is the stretched raster value?  Mean of all twelve months?  Sum?
2) I'd like to create an attribute table for further analysis, but can't do this for a multi-band raster.  Suggestions?

Thanks in advance for your help,

Greg
