Current and voltage from PV ( LTS25NP , LV 25-P)

Hi
So in my design I am going to sense two PV panels in series ( Both voltage and current) to extract the Maximum power point (MPPT by arduino)
so the input of both sensors will be the PV output
and the output of the sensors will be input to arduino uno

My question is how should I connect these sensors
