Re: [TRNSYS-users] Solar radiation of tilt surface



Adnan,

  All modes of the solar radiation processing algorithms (whether they are in Type15 or Type16) take into account the slope of the receiving surface (as well as the surface direction that it points).

kind regards,

 David

Hello everyone,

i am trying to evaluate the effect of tilt roof angle  on solar energy gain of the building. my building has all window on roof. it seems all works well but my results are from increasing roof angle 1 degree from 15 to 30 degree solar gain decrease constantly. but infect it should increase near 25 somewhere and again should decrease. i don't know which mode of solar radiation processor is dependent on angle of the surface... can anybody help me with this..
