We field tested the concepts this morning and the answer is
"yes" (inter-row shading in portrait mode: bad -- in landscape
mode: less bad).<br><br>

99% of the time, we install modules in portrait mode. We find
ourselves installing a set in landscape with some short inter-row
spacing, due to roof vents. We are using Solarworld SW230
modules.<br><br>
It is my understanding that shading the short edge of this type of module
is much more detrimental to the output than shading a long edge.
This is because of the manner in which the cells within the module are
arranged in series. I understand that one string is on the bottom
half of a module and the other on the top half of a module in the
landscape orientation. In order for the module to cease power
production, you have to shade at least one cell from each of the two
internal strings. Therefore, you need to shade more than half of a
module in the landscape mode before the module before the output declines
drastically.<br><br>
Is my understanding here correct? I will be testing this tomorrow
if weather permits.<br><br>
Thanks in advance.<br><br>
