micro-inverters or optimizers when shading is major issue ?

If there is not much space, a pretty tall array works. But you give up ease of snow removal or
making them tilt. With multiple rows, more, lower arrays do not really take a lot more land, because
the shadow is shorter. 2 high work well here, everything is in easy reach. With both landscape and
portrait mounts here, it is much easier to keep snow off the landscape, about the same height but
my near vertical landscape mounts have an 8 inch space and 40 inch ground clearance.

After this weekends storm, the near vertical panels were completely clear, but the summer angle
panels had 3 inches of snow and ice. Bruce Roe

Snow is not a big consideration here in central NC.

If I decide to go 8-wide portait, I guess I could do two rows. That many more concrete piers to do, though they could be smaller.
