Learn how to measure solar panel output current and power using a digital multimeter. Step-by-step guide for DIY users, plus FAQs on solar panel testing.

Note: You can more easily measure PV current by using a clamp meter, which I discuss below in method #2. That’s right — you can use a multimeter to measure how much current your solar panel is outputting. However, to do so your solar panel needs to be connected to your solar system.
How to Measure Solar Panel Output with a DC Power Meter This is a DC power meter (aka watt meter): You can find them for cheap on Amazon. Connect one inline between your solar panel and charge controller and it’ll measure voltage, current, wattage, and more. Here’s how to use one. 1. Crimp the MC4 connectors on, if needed.
Safety gloves and glasses to protect against electric shock. Follow these steps to accurately measure the short-circuit current of a solar panel: Select a Sunny Day: Ensure you are measuring Isc on a bright, sunny day to get the most accurate reading. Set Up the Multimeter: Turn on the multimeter and set it to measure current (Amps).
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.
Connect the Multimeter Leads: Attach the multimeter leads to the positive and negative terminals of the solar panel. Ensure the connections are secure. Measure the Current: With the multimeter connected, the current displayed on the screen is the Isc of the panel. Note the reading.
Your multimeter is your best friend when testing solar panels. You can use it to check: Here’s how: Multimeter — I recommend getting one that is auto-ranging. Also, a simple voltmeter won’t work here. You need a multimeter that can measure both volts and amps. 1.
