Hi,<div><br></div><div>I am simulating a PV system with TRNSYS. In TYPE 15-2 there is a parameter for the tracking axis. </div><div><br></div><div>One can choose between the 4 following options:</div><div><br></div><div><i>The type of surface for the radiation calculations: 1 = fixed surface (no tracking), 2 = the surface rotates about a vertical axis in order to track the sun, 3 = the surface rotates about a fixed (user-defined) axis, 4 = the surface 2-axis tracks such that the beam radiation is always normal to the surface.</i><br clear="all">
<br></div><div>Regarding option 3, how to enter the user-defined axis (X-axis for example)? In other words, the collector area shall optimize its orientation by rotation around a horizontal axis.</div><div><br></div><div>
Thanks in advance!</div><div><br></div><div>-- <br>Mohannad Bayoumi<br>
