No, the collector is a fixed surface based on the value of
parameter 7 in Type109. Please note that in the more recent versions
of TRNSYS, Type109 has been replaced by Type15. The collector model
takes into account "incidence angle modifiers." That is to say that
the optical properties of the collector cover change depending on
the direction of the beam radiation. You therefore pass the
incidence angle and the collector slope from the weather reading
processing component to the solar collector component. <br>
Just to be sure that there isn't an error in the example that you
are looking at, the Type109 output "angle of incidence for surface"
is connected to the collector input "incidence angle" and the
Type109 output "slope of surface" is connected to the solar
collector input "collector slope" <br>
Kind regards,<br>

hi,<br>
<br>
I'm testing out at which angle the solar thermal collector is
set, which will have the most useful energy output.<br>
<br>
When i looking at the connection in the hot water system example
in trnsys. i notice that the angle of incidence for tilted
surface and slope of tilted surface from the Type 109 weather
are connected to the solar thermal collector incidence angle and
collector slope.<br>
<br>
Does it mean that the solar thermal collector is automated to
follow the direction of the sun during daytime?<br>
<br>
Thank You<br>
<br>
