[TRNSYS-users] Modeling of PV panels using Type94

[David Bradley]

Chun Kwong,
  Type94 can act as a PV panel that is directly connected to a load or 
it can act as a PV panel that is attached to a maximum power point 
tracker (MPPT). If your PV is directly connected to a load, then you set 
input 3 to that load voltage (which may be calculated by an equation or 
by another model). Type94 will iterate internally to find where its 
operating point is on the PV's current-voltage characteristic curve and 
will output the voltage as output 1. Typically this will be the same as 
the input voltage once convergence is reached. If your PV has an MPPT on 
it then you do not need to worry about setting the input voltage and you 
should only pay attention to outputs 4, 6, and 7.
Kind regards,
 David
