I am finally getting around to putting some photovoltaic panels under the
bracing Australian sunshine that hammers down on my roof (not nearly so
attenuated by stratospheric ozone as your watery northern-hemisphere
However, the people who built my house, back in 1901, put up a brick
chimney so tall that you could build an extra storey on the house without
extending it, if you felt so inclined.
Like a gigantic gnomon, this sweeps the roof each day with its shadow.
Now, in practice, we will get around the worst effects of this shading by using
In theory, however, it would be much better to replace some, but not all, of the
chimney's bricks with glass ones, fixed with glass mortar.
First, this would create the momentary, corner-of-the-eye illusion of a stack of
unsupported bricks high above the house. The cut-off would be ragged, with
one or two courses containing both glass and opaque bricks, as if to suggest
that individual bricks might be falling off as you watched.
Second, it would have a dappling effect on the sunlight, a bit like that of a
dimpled beer mug. Dimpled beer mugs are good.
The inside of the glass, at least, ought to stay clean, because what's under
the chimney is no longer a wood fire but a gas one.
The residual stack of opaque bricks resting on top of the glass ones could be
embellished with a bit of plaster sculpture so that it actually had a gigantic
gnome on, possibly aping King Kong.

||Rather than demo and rebuild, could you not wrap the chimney with a covering containing fiber optics to redirect sunlight so that, although there would still be shade, certain panels will always receive twice the light?
||You could mount the panels on a giant fan shape, pivoted on the chimbley, so that it rotates to track the sun.

always a gap where the shadow is. Mount the
