Measuring the full power output of a solar module requires a load. However, as a first step, we can use a simple multimeter to measure with no load to get the open current voltage, (V OC) and short circuit current (I SC). For large outdoor modules, any multimeter with a current scale that goes to 10 A (amps) and 50 V (Volts) will work.
