I am trying to simulate the PV module model with varying irradiation (after considering the beam, diffuse and reflected). I have modeled the the PV module using the mathematical equations in Simulink and managed to get the P-V & I-V curves for constant values. But I get error when I input a signal. If anyone know how do this to kindly assist.
I have managed to use a signal builder block. No errors now. Thank you for this. I will study the behavior of the results I am actually getting at the output if they realize what I am looking for.
Thanks again. @Qasim Ajao
Hi shaibu Ali Juma, Thank you for your Question.
There is another approach to feed variable data for solar irradiation. If you are trying to simulate a PV module, In order to get accurate and precise results try to look for actual solar irradiation data of any place you like and then download it in CSV or Excel format.
Then with the help of from workspace block in matlab you can directly use that data for variable irradiation level.
The website to access the data is: https://nsrdb.nrel.gov/
I hope this will work.
