[TRNSYS-users] simulate a PV-System with Type 94a

[David BRADLEY]

Julian,
  Type94 (and Type194) have two sets of power ouputs. One is the power 
at the maximum power point and the other is the power at a 
user-specified load voltage. I would guess that you left the "load 
voltage" input set to zero, which is why the output power is zero. Most 
PV arrays have a maximum power point tracking device on them so you 
should use the outputs for the power, current, and voltage at the 
maximum power point.
kind regards,
  David
