Hello,<div><br></div><div>I have 15 minute real data from a PV system . I know the ambient temperature(F), total radiation (kJ/h-m^2) and power(W) for every 15 minute. </div><div>I created a model and wanted to compare real power values and simulation results. When I run the simulation, the results are not close, the simulation results are so lower than real values. </div>
<div><br></div><div>I did the necessary changes like slope or azimuth according to PV system information.</div><div><br></div><div>I created a input file and the model takes the ambient temperature and radiation values from it. I chose 0.25 hour as "simulation step" in Control cards. Also,in the Type 9(Input file) I chose 0.25 hour as "Time interval of data".</div>
<div> </div><div>My question is: </div><div><br></div><div>The PV type gives power production as kJ/h, so do I need to do any conversion to compare with 15 minute real data or TRNSYS does that because I changed the time steps?</div>
<div><br></div><div>PS: I am attaching my tpf file and input file. </div><div>Also, when I converting power production from kJ/h to Watt , I also multiplied 637,because there is 637 panel in the system. </div><div><br></div>
<div>Thank you.</div><br>
