<p style="margin: 0in 0in 8pt;"><font face="Calibri">First of all, David thanks a lot for your advice for comparing type 194 and PV T collectors under electrical library ( TESS). In my system it only shows [1. Interactions with detailed building models (type
563) 2. Interactions with simple building model (type 560)]</font></p>

Efficiency of type 563 is very low about 1.5% (thermal + electrical) from its output and also stayed same by using an external equation. (Does anyone else face this problem?)

Type 560 and type 563 don’t have parameters such as “Module short-circuit current at reference conditions” as in case of type 194. (that’s why I don’t think, it’s a good idea to compare the type 563 efficiency with type 194) (Any suggestions?)

I would steer you towards comparing against the PV/T collectors that are available in the TESS Electrical library if possible instead of Type50.<br>
kind regards,<br>

<p>Hi David, </p>

<p>Thanks for answer and suggestion! Actually, I am trying to compare the performance of simple PV ( type 194) and PV/T collector type ( type 50E thats only the one which is providing the power output). </p>

<div><span><span>Sandeep,<br>
the SolarCellPerformance() subroutine contains some code that allows it to model both standard flat plate and concentrating PV collectors. CL and CH refer to values of the concentration ratio; the ratio of the aperture area to the absorber area. Ao is a coefficient
that is used in the concentrating PV collector model. Values for certain panels are given in the \Trnsys17\Examples\Data Files\Type50-SolCel.dat file.
<br>
<br>
I might mention as a side note that unless you absolutely have to use a call to the
</span></span><span><span>SolarCellPerformance() subroutine, I would recommend that you rely much more on the PV modeling methods in Types94 and 194. They are much more up to date modeling algorithms.<br>
