Remove the towel and read the current on your multimeter. Adjust the tilt angle of your solar panel until you find the max current reading and compare this number to the short circuit current (Isc) listed on the back of your panel. The short circuit current you’re measuring should be close to the one listed on the back of the panel.
These two metrics are essential for determining the power output and overall efficiency of your solar panels. Voltage (V) measures the electrical potential or pressure that drives the flow of electricity in a circuit. In the context of solar panels, voltage indicates the potential energy generated by the panels.
To accurately assess a solar panel’s performance, measure the voltage and current output using a multimeter set to the appropriate settings. Analyze the voltage output by using a multimeter set to measure DC volts and ensuring correct connections for accurate readings.
Together, voltage and current determine the power output of your solar panels, calculated using the formula: Power (W)=Voltage (V)×Current (A)Power (W)=Voltage (V)×Current (A) For example, if your solar panels generate 30 volts and 5 amps, the power output would be:
1. Locate the open circuit voltage (Voc) on the specs label on the back of your solar panel. Remember this number for later. For this method I’m using the Newpowa 100W 12V panel. It has a Voc of 19.83V. 2. Prep your multimeter to measure DC volts. To do so, plug the black probe into the COM terminal on your multimeter.
When evaluating solar panels, your multimeter is your closest buddy, and it is necessary for this kind of testing. It can be used to verify: On the label on the back of your solar panel, look for the open circuit voltage (Voc). Connect the red probe to the voltage terminal and the black probe to the COM terminal to set up your multimeter.

Measuring the Power of a Solar Panel
We said previously that the output power of a solar panel mainly depends on the electrical load connected to it. This load can vary from an infinite resistance, (∞Ω) to a zero resistance, (0Ω) value thus producing an open-circuit voltage, V OC at one end and a short-circuit current, I SC respectively, at the other. Then we need to be able to find an external resistive value …
