In my case, I use
a high tilt angle to control summer stagnation temperatures.
I think that the combination of a relatively large collection area coupled with
a high tilt angle (which gives improved winter performance) will give very good year round performance and a larger winter time solar fraction.
Residential and small commercial systems generally have
higher tilt angles, likely matching the pitch of the roofs these systems are often installed on.

Our dining room is small so it does nt take up a lot of space, and it adjusts for them to sit up
higher, or at an
angle tilted back.
The stopes are a meter
high and they
tilt downward at a steep
angle, so you go down them almost like a slide, passing from one tunnel to the next.
Prior studies of atomic - level grain boundary and segregation structures have been mostly focused on small -
angle or special symmetrical
tilt and twist boundaries with
high symmetries and well - defined periodicities in artificial bicrystals.
The extension doesn't necessarily need to make the fence much
higher, as long as it
tilts inward at about a 45 - degree
angle.
Dual - axis tracking systems do this, too, while also modifying the
tilt angle as the sun is lower or
higher in the sky.
Collectors that are stagnated in the summer at
tilt angles close to the local latitude will develop temperature that are (I think) to
high for PEX — temperatures over 250F.
Of course at that
high a latitude, it has to be interpreted in light of the
higher degree of
tilt of the Earth's axis which in the early Holocene would mean a
higher sun
angle for the North.
The included stand offers both
angle and height adjustment,
tilting between 20 degrees backward and 5 degrees forward, and raising from a height of 17.5 inches up to 22.3 inches
high.
