Thermal Input Solar Field was created by Paul Gilman

I have a question concerning my CSP model in Solar Advisor Model. Is there a possibility to use the elsewhere calculated thermal input of the solar field for SAM? So that there is no need to fill in the Solar field and SCA/HCE input parameters?
The CSP Generic Solar System model option allows you to describe the solar field using a table of optical efficiency values. Is that what you need?
To use the model, when you create a new file or case in SAM, choose the Generic Solar System option under Concentrating Solar Power.
Best regards,

Paul.

Hello Paul, thanks for the fast answer.
The generic Model only provides a table where you can type in optical efficiencies as a function of various azimuth and zenith angles. I do have hourly weather data of 1 year and the corresponding DNI, where cosine-effects, etc. are already included.
Best regards,

Peter

Hi Peter,
I don't think I quite understand what you want to do, but it sounds like it may not be possible with SAM. What exactly do you want to use as input to the model? '
If you have your own weather data that you would like to use with SAM's physical trough model, you can either use SAM's TMY3 Creator , or use a text editor or spreadsheet program to create a file in the SMW format . You will need data for each of the columns that appear in the table on the TMY3 Creator window.
If you have solar field thermal output data from a different model that you would like to use as input to SAM's thermal energy storage and power block models, there is not a way to use that data in SAM.
Best regards,

Paul.

Hello Paul,

my input data for a whole year looks as follows:
