Re: [TRNSYS-users] Solar-tilt angle



Saikat Das,

 There are two ways that you can do this. If you want to set the slope and azimuth of a surface (or axis) and have it remain fixed throughout the simulation or have the surface track the sun in a prescribed manner then you can use Type15 as Jeff mentioned in his email.

 If, however, you want to create a different tracking scheme or if your surface's slope and azimuth follow some other pattern then you can use Type15 to get the solar radiation on a horizontal surface and use Type9 to read a data file containing slope and azimuth. The results of Type9 and Type15 can then be passed to Type16 for processing. I saw this technique used in a project some years ago that was looking at the energy use of a large cruise ship, which was treated as a building whose walls and windows changed azimuth according to the ship's direction.

kind regards,

 David

I am trying to study the solar power generation of a photovoltaic panel by varying the tilt angles in different months. In Trnsys is it possible to do such a study? If it is possible then where do I input the tilt angles?
