Hello,<br><br>I need to use a type 99 for my simulation. I am using the mode 3 of this type. According to the help, I just need to provide data concerning the total radiation on a horizontal surface and the diffuse radiation is estimated using Reindl's reduced correlation. The problem I am encountering is that when I am using a printer to see if the output "total radiation on a horizontal" of type match the data that I provided, they don't (even after a unit conversion). Could you help me figure out why? Thank you in advance!<br>
