[TRNSYS-users] PV Example in TRNSYS

Fred,
 I'd recommend using Type194 and running the EES plugin (icon down in 
the lower left hand corner of the parameters tab window). That plugin 
basically takes information that can be obtained from the manufacturer's 
sheets and turns it into the parameter list for Type194.

 As for validation, there is some evidence that our models overpredict 
actual PV performance a bit. Its not entirely clear whether this is 
because the manufacturer's spec sheets are based on ideal conditions in 
a lab that aren't seen very often in the field or if there is some other 
cause. However, don't forget the the PV model is just for the panels and 
that you need to account for electrical losses in the DC bus and in the 
interverters and power conditioning equipment too.

Kind regards,
 David
