Hi everyone, I have exactly the same problem, the differences are quite small but it still can have a real economic impact on our studies. I can detail more what I did. So, I ran a batch simulation with ticking the box "Create hourly files", then I set my output files to "Monthly values". My batch simulation is about to simulate over 10 years of functioning, so my only parameter is "Year of simulation". After that I just compared the different values of the variable "Energy injected to the grid", and the results are : batch normal 0 43229 43220 1 43166 43151 2 43040 43017 3 42894 42882 4 42729 42729 ... After that results are the same, but so for the first years there are some differences, which can also be noticed at month level. For information, I just let the default values for the degradation over the years and I ticked the box "Keeps calculated mismatch values". So my question is the same than sailerthomas, how is that possible ? Thank you for your answer, BlackBird
