Be careful - when you set the slope of the collector in the collector 
model you are NOT setting the slope for the radiation.  The best way to 
do what you want is to set the area as a parameter in the collector 
model and then set the slope and azimuth of the collector surface in the 
Type 15 weather component.  Then hook up the incident radiation terms, 
the incidence angle, AND the slope from the weather model to the 
collector model.  Refer to the collector examples for reference.
