One optimization that I am considering now, in the case of the vertical walls, is to put

the solar panels horizontally instead of vertically, so it would be more easier to incline

them, like 10" away from the wall, looking a little bit like the shutter of a window.

The inclination for a 10" base and 39" high triangle would be about 15 degrees.

For the purposes of computation, they are an 85° tilt from horizontal.

I could then have 8 panels on each of the east and west side of the stairways cabin,

and may be 8 flat panels on top of the stairways cabin, or a total of 24 panels.

For the elevator cabin, I could have then install 2 panels on the east, south, and west

with the same inclination of 15 degree and 2 panels on the roof. or a total of 8 panels.

So the total would be 32 panels, with

- 10 panels flat,

- 10 panels east and west with an inclination of 15 degrees,

- 2 panels on the south with an inclination of 15 degrees.

Assuming 240W panels. Those are 60 cell, so you can fit 3 in series on a 150V controller, and that's the desired config. That makes your array combination a little tricky and may necessitate multiple charge controllers.

Fall short Nov-Jan and produce far more in the spring/summer months.
