I am afraid that you might that there is not a huge amount of
experience on this forum with the STEC library components. They have
been offered as an "as is" add on to those who want to use them but
it has been quite some time since they were updated and I'm not sure
how many people are actually using them on a day to day basis.
You're going to need to build the system up one component at a time
and use a lot of instances of Type65 to plot out output variables
that will show whether the system is operating the way you think it
should. Start with a weather component and simply plot the solar
radiation and the ambient temperature using Type65. Then add the
solar field with a constant flow rate and look at the field outlet
temperature. Does the plot make sense? Is the flow coming out the
same as the flow going in? Next, add some storage and another online
plot trace. In this way you will not only learn how TRNSYS itself
works but you will understand each of the models that you are
implementing in your system as you go.<br>
Kind regards,<br>

<p>Hello everyone,</p>
<p> </p>
<p>I'm new in trnsys and i have a project for the university to
simulate a solar thermal storage to store energy from parabolic
troughs. I use ,from stec library, the concrete storage(type
430) the stoco controller(type 431) and parabolic troughs(type
396) just like the stec example STEC_STORAGE. The solar field
is 20000 m^2 just like the example. Also, and the temperatures
are same. The difference with the example is the solar field,
where i use type 396. The problem is that the used flow is too
short. Can you help me what parametres should i change in order
to have valid results?</p>
