Re: [TRNSYS-users] Type 16 radiation processor



Dear Javier,

I am not sure what are you "named" database.
However, the parameters to put intpoo Type16 are depending of the time in your experimental data.
If the data are in "solar time", you should put on the 9th parameter -1.
In case that your data are in "local or legal time", you should use 1 and also yuou have to specify the shift in solar time (parameter 7).
How to calculate this value is explained at tyhe Manual 5 (Mathematical Reference)

In both cases, take care also to feed adequately the Starting day (parameter 4) and to connect correctely "time of last read and next read"

Regards,
Jaume Salom

Dear all:
I am Javier Mota from 3i-ingenieria, Madrid
We are simulating a 2 axis PV central
Now, we have experimental data of radiation on horizontal.
We must traslate this data to a surface ortogonal to sun position.
Then we feed pv with the radiation of this surface.
For tis purpose we have a experimental data base with time and radiation on horizonta.
But type 16, parameter 9, solar time must be at solar time or not.
So I have 2 question; once refered to the database that feed type 16  and a second refered to the value of parameters and inputs that type 16 reads
Well, if we have DATA BASE in UTC+1, for Albacete,( the city in spain of the PV central), when I feed the type 16 imputs time of las read and next read,  should i use in the data base local time LST, this is TIME UTC+1 corrected with the longitude parameter and Equation of time; and with this time I feed inputs in type 16 ,(time of last read and next read)?
And then in type 16  Shoul i use parameter solar time =1 and use the shift parameter that it should be as the longitude of the local meridian as it is explained in manual?
Is this way the correct way to proceed?
thanks in advance.
