Array's Electrical Behavior Tool

[Shy A]

Hi,

Is there any way to output the annual loss of energy due to 2 different orientations? I see in the graphs that you provide the instantaneous loss of energy - so the data is available, but not for an annual summation as far as I can see.

Thanks,

Shy

This is just a pedagogical tool, for understanding the mismatch phenomenon on one I/V curve.

You can evaluate the mismatch loss between 2 different sub-arrays with strings in different orientations, connected on a same MPPT input, by performing a full simulation using the option "Heterogeneous fields - Mixed orientation", and compare with the results of 2 different systems in each orientation.

For parallel strings, the mismatch effect due to different orientations is usually very low.
