Equivalent Circuit For Solar Cell Solarex MSX 005F Pilot Cell CPC1824 For Simulation

[mraiton]

Guys,, can you help me with this please??

i need to know the value of Rseries, Rshunt and other parameter.

or you can give me anything so i can simulate those 2 solar cell..

thanks..

If you find the specifications for Pmax, Vpmax, Ipmax, Isc, & Voc it should be possible to calculate the mentioned parameters more or less accurately.

 

[mraiton]

here's the specification for Solarex
Voc = 4.6 V
Isc = 160 mA
Pmax = 500 mW
Vpmax = 3.3 V
Ipmax = 150 mA

And for cpc1824 i can only find these
Isc = 100 uA
Voc = 4 V

help me to find those parameter please..
or how do i find/calculate those parameter?

Ok. Do you know how the V/A curve from a panel looks? It's quite squarish - although with slopes, and has a rounded knee point.
There will be some error involved in that the knee point will not be rounded in the simulation.
So, you have a constant voltage supply of 4.6V with a series resistance of (4.6V - 3.3V) / 0.15A = 8.67 Ohms.
Then there is a constant current limit of 150mA in series with that - that seems to have a shunt resistance of 3.3V / (0.16A - 0.15A) = 330 Ohms.
I have not calculated the CC part for use in simulations before so I might be mistaken on some detail there.
The other panel has insufficient data but you may draw out the curve(s) and use a graphic way of transposing/comparing the data and solving it that way.
