<p>Janeet,</p>
<p> Your first two questions are things that have been fixed in the
most recent version of TRNSYS. I am not sure when they were fixed
but I think they have been fixed for awhile. Which version of
Trnsys are you using? If it is an older version, you can fix them
by modifying the proformas yourself. The errors are in the
proformas and not in the code.<br>
</p>
<p> As for your third question, you'll need to send that to your
distributor. If you aren't sure who to contact, send me a direct
email and I will point you in the correct direction.</p>
<p>kind regards,</p>
<p> David</p>

<div><br>
</div>
<div>I am trying to simulate a parabolic trough concentrating
collector using the type 50e-mode 8. Have included the defualt
SOLCEL data file. </div>
<div><br>
</div>
<div>Had a few queries:</div>
<div>1. Parameter 3 - ratio of aperture to absorber area - max
allowable value is 1 whereas the concentration ratio of 55 is
to be simulated. Please can you advise a solution to this.</div>
<div>2. Input 4 - Incident radiation is required in KJ/hr or
KJ/hr/m2?</div>
<div>3. Input 7 - Voltage applied to array - anything above 2V
gives unrealistic output.</div>
<div><br>
</div>
<div>Thank you for your time.</div>
<div><br>
</div>
