120 degree azimuth [RE-wrenches]

[Darryl Thayer]

Hello again
If you are insecure about PVWatts do a run on
RETscreen it is free, and I have a system that has
been monitored and results published, that compared
actual measured results with RETscreen, the results
were very good.  It made a believer out of me as to
the validity of calculated results.  The ten year
average was very good.  The biggest error was in the
winter here in Minnesota, and perhaps this is due to
excessive snow or frost cover.  Or I think the climate
models are off in the winter.      
Darryl

PS send me your latatude and longitude and I will make
a run on RETscreen/
