[TRNSYS-users] Difference between Surface 1/2/3 in weather file

[dev sharma]

Hey All,

Can someone please tell me the difference between surfaces 1/2/3 etc,
when I use type 109 to read weather file? I ask this because the
radiation curves incident on these surfaces are different. For surface
2, the beam radiation becomes 0 during the summer months, which is
pretty shocking.

Thanks
Dev Sharma
