I am trying to measure and record the output of a single PV panel for a long time. The panel a 275 Wp with Voc=38.13 V and Isc=9.2 A and Vmpp=31.25 V and Impp=8.81 A. Should I calculate the resistor size based on the MPP Voltage and current (31.25 V/8.81 A = 3.5 ohm) and connect a 3.5 ohm resistor.
