[RE-wrenches] Inter-row shading, additional information

[William Miller]

Friends:

I was incorrect on one point in my previous post on the subject.  The 
SolarWorld SW230 is comprised of one series string of cells.  It acts 
somewhat like there are three strings because of the bypass diodes. If you 
shade one cell of one group, the bypass diodes kick in and allow the module 
to continue to produce power but at a reduced level.

Our test showed that if the short edge is shaded for more than half of a 
cell width on the narrow edge, the total output caved.  The same shading on 
the long edge reduced output minimally.
