Feb 17, 2006 #2 willard3 Mechanical Jan 14, 2006 1,437 What are you trying to do, calculate the solar loading on glass? ASHRAE tables give irradiation at solar maximum and you could, through simple geometry, find the solar component at other angles. You would first have to find out the incident angle on that date at your latitude and longitude, but these are readily available. I hope this isn't a homework problem....... Upvote 0 Downvote
