Solar Freaks

Hello ,

I am new to solar PV . In last two days i was reading about the MPPT and it's importance. I have also read that a DC-Dc is needed to convert SOLAR PV output to battery input.

My question is " How to acheive MPP" as it's particular voltage and current. That point can only be reached when a particular impedence is offered to solar PV. all the algorathims talk of only volatge control which is the output of DC-DC , not the input of the DC-DC , which is output volatge of PV.

Please remove my silly doubt, why silly bcoz' i know i am missing the point .
