I am attempting to use the Area Solar tool. However I am having a difficult time understanding what exactly any of the solar outputs represent. I would like to calculate the daily integrated solar value for any given pixel within a DEM's domain. But with an output of Wh/m^2, what does this value represent? Is this truly the integrated daily solar radiation value or something else? If the tool is actually calculating integrated insolation shouldn't the output simply be in W/m^2?
Cheers,
Fred
