[TRNSYS-users] Problem with photovoltaic simulation, help required

   Please keep in mind that there are two different parameters that ask 
for information about series configuration. The first (parameter 10) is 
the number of cells that are wired in series within a module. The second 
(parameter 11) is the number of modules that are wired in series in the 
array. The first, will probably cause little change in results and 
really should not be changed unless you are also changing the other 
parameters that describe the module performance (short circuit current, 
open circuit voltage, etc.) The second of the two parameters (parameter 
11) should affect the array voltage but not necessarily the array power 
(so long as the total number of modules stays the same). Make sure also 
that you are looking at the array maximum power point power.

   In order to change the parameters of Type194 you can use the plugin 
(icon in the lower left hand corner of the parameters tab). You might 
also consider using Type94, which is a simpler model that requires 
parameters that can typically be read directly from a manufacturer's 
specification sheet.
Kind regards,
