How to input solar Irradiance data into PV array?

I am trying to model a solar cell system.

I understand that the PV array system has 2 input, Irradiance and temperature. I could make the Temperature input constant.

I have real data of the fluctuating Solar irradiance and I am hoping to monitor the change in PV output, but how do I input the Irradiance data to my model?

Did any of you search the File Exchange for e.g. "solar PV" or read Read Text File to add Simulink Blocks ?
