Vertical E/W bifacial system with different orientations


Recommended Posts

Dear all,

I'm trying to simulate a vertical E/W system with a 90° tilt, both 90° and -90° azimuths. I designed it to have 90° azimuth tables alternating with -90° azimuth structures for better yield(half of the module's front face east, the other half west).

Currently, I'm getting an error message:

I changed the advanced parameters for pitch RMS limit and max. tilt axis, but it doesn't solve the problem.

Given the program limitations for the unlimited 2D sheds model, is it even possible to calculate it? 

Thank you in advance!

No, at the moment it is not possible to have two bifacial orientations. This will only be possible in version 8, to be released at some point (in principle in the first half of) this year. The annual yield will not change much if you use only one orientation, though, unless you are overloading your inverters. However, the hourly distribution will change, of course.
