Hello Everyone, I have to develop a program to track the maximum power point of solar cell continuously, as i am new to Lab View its getting very hard for me to understand some terms. still i tried to develop some algorithm by looking some research paper, but i have some confusions related to case structures and also i don't know whether i am going in right path. Can anybody give suggestion on this. It will be very helpful for me. Thanks in advance.

That's how I would understand it. MPPT would mean that you continuously calculate a new value for the voltage of the source meter, measure the resulting voltage and current, calculate the power and see if it is higher or lower than before. If it is higher your previous correction was in the correct direction and you need to continue to correct towards that direction. If it is lower you passed the MPP point and need to backtrack a little by inversing the direction of the correction. Pretty simple. but this only really makes sense if you want to operate the cells under real world conditions where the available light will continously change. The MPP of a solar cell changes depending on temperature and of course available light (photons). That is why solar cells are normally operated with MPPT to get the maximum possible power from them at sometimes quickly varying environmental conditions. You seem to do simply a characterisation at a specific light intensity by simply sweeping the DUT and then you can take those measurements and calculate whatever you need from them.

MPPT tracking using keithley 2400

Solved!

Hi,

Did you solve your problem?
I am trying to track the mpp using Labview, but no success yet.

I am using Keithley 2634
