A Questionable Solar PV Installation

When I walk by a house with a solar PV array, I often think about the specific design.  Is it facing the right direction, at approximately the correct angle, etc?  In our neighborhood, there is such an array built too close to the chimney, the shade from which impairs its effectiveness.

That’s why the pic at left got my attention.  One needn’t be a senior engineer to see the issue here.
