Avishek,
   It appears that you have a somewhat older version of TRNSYS; in the 
more recent releases the "more" button fields of Type94 are all 
populated and give some information that would be quite helpful in this 
case. I would highly recommend that you contact your distributor and get 
access to the updated version. Once you do, you will need to right click 
on the Type94 in your project and select "replace" from the context 
menu, then browse to find the Type94a proforma.

   Type94 (and Type194) are a little confusing in that they calculate 
two power outputs; one is at a known load voltage and the other is at 
the maximum power point. You have plotted and printed the array voltage 
(note: not the power) at a voltage that is taken as an input to the 
model. You load voltage is currently set to zero; thus the result you 
are seeing. I would recommend that you look instead at Type94 output 5 
(Power at maximum power point).

   Don't forget to connect the other inputs to Type94. Your values of 
ambient temperature, beam radiation, diffuse radiation and angle of 
incidence of beam radiation are all constant and set to zero.
regards,
  David
