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 On 4/24/2015 8:29 AM, avishek ray
