<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>Lee Han Kiat<br> </div></body>
