virtual sub-array

[c.katharotiya]

Hello,

How to difine virtual sub-array in one physical sub-arrry in terms of using solar edge optimizer with East-West orientations to get the module mismatch loss in the simulation report?

In my case, I have 1 string with 20 modules, and 2 strings with 33 modules.  I know, that I can't define a mix orientation in a subfield but Could you please let me know what would be the best solution?

Please see the attached pdf with string plan.

Thank you in adavace!

Hi,

Please check this tread, as it could contain the answer to your question.

Hello,

Thank you for your reply.

I have rade that tread, which you suggested me. As you said in that tread, we can achieve a similar result by creating two separate sub-arrays, one for each orientation, then attribute the strings to the same inverter. In this case, we would have each string with only one orientation. Therfore, PVsyst does not result module mismatch loss in simulation report.  However, in real case, we would have mixed orientation in one physical string and module mismatch loss occures. 

what would be the another approach to set up string configiration (by considering mixed orientation)?

As mentioned in the other thread, the only way to mix orientations within a string is to use the averaged orientation option.

This also means the transposed irradiance will be the same for all your modules sharing this orientation, so it won't generate any mismatch. Other effects (notably shading) will use the real orientation.

But in your case, it should not change anything : string mismatch should not occur with module level optimizers. 

 

You can still change that behavior in the detailed losses menu, Power Loss at MPP.
