Andy,
My system http://www.solarsolar.com/oursys.html has 3 each #2 utility wires
shading it most of the afternoon. The shading runs from the array southwest
corner to the northeast corner. I was concerned about shading, but have seen
no effect. I think the reason is the width of the shading is narrower than a
solar cell's width and the shading lines are diagonal.
Best regards,
Joel Davidson
