If you don't have the data you can only draw a representation. Volts on one axis and amps on the other.

Sara,
I have a thread about my experience with some solar panels, and the VI curve for them was nothing like the "typical" curves I found on the web.
If you want decent data I'd recommend getting the actual solar panel and doing experiments with various resistor loads.

Hey Bean,
thanks for replying.
well, i had the same idea. in the university, they have installed the pv panel which is very old. i went there and ask them for data of this panel, just to try with that.
But· i don't think if this data would be useful in my case. because when i put them in the excel i will find the other diagram. i send you the data and also my excel which i have finished. but it does not look like a IV curve.
