Grae Posted August 12, 2016 Share Posted August 12, 2016 Hi,We have been looking into the .ond files and utilising the efficiency curves for different voltages. We are currently not using the functionality of efficiency for 3 voltages as we seem to have an issue in generating the curves. It appears when you set the voltage to a certain threshold, you have to set all three voltages manually as they are not generated from the first point entered. Is this an issue, is PVsyst able to interpolate the remaining two efficiency curves, from the original defined efficiency curve (i.e. set the max efficiency curve at a low / mid / high voltage and the other two curves are generated based on this)?When defining all three voltages with the same Max Euro efficiencies, we obtain the same loss as not using these curves (i.e. having this option ticked or unticked). Sometimes we have seen the profile curves setting a very different profile curve to the curves observed on the datasheets. However not all datasheets have these curves which makes this checking and definition impossible.Many thanks,Grae Link to comment Share on other sites More sharing options...
