[TRNSYS-users] Solar-tilt angle

[David BRADLEY via TRNSYS-users]

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
