Type16 calculates the angle of incidence on each of the surfaces that you define. If you define a horizontal surface (slope = 0, azimuth = 0) then Type16 will calculate the incidence angle on that surface.

Hi trnsys users,
I am using type16c to get diffuse rad from global data radiation. But type56 needs angle of incidence on horitzontal, and I don't know how to get angle of incidence on horitzontal because this type doesn't give it as an output. Does anybody know how I can get it?
Thanks in advance

Dear Bastien,
"Time of last data read" and "Time of next data read" need to be connected from your external data reader, Type9, to your Type16 radiation processor, respectively. I am not 100% sure why - most likely a historical or fortran reason, but please make sure to connect those.
Best regards,
Matt Duffy

Subject: [TRNSYS-users] Type 16c_Solar Radiation Processor
Dear all,I would like to estimate the solar radiation on a tilted surface with Type 16c by choosing Mode 2 (Total radiation surface on a horizontal surface, ambient temperature and relative humidity datas are known). These threes datas were measured with a step time of 10 minutes from November until Februar. I want to calculate the effective radiation on a northern and a southern orientation, in order to estimate the effective solar gains with a step time of 10 minutes.I can't obtain correct results because I think I don't understand the inputs 4 and 5 of Type 16c. What does "Time of last data read" and "Time of next data read" mean?Is it possible to use this type with a timestep of 10 minutes but with measures on only 4 months (not a complete year)?Thanks for your help and your answer!Bastien
