To identify a solar panel's polarity, check the MC4 connectors (male/female) or use a multimeter (DC voltage mode)—positive terminals show +V (e., +18V for a 20W panel), negative reads -V or zero. Wires are often red (positive) and black (negative), or labeled. . If your solar panel does not have clearly labeled terminals, you can often identify the polarity by inspecting the junction box, which houses the wiring connections. Inside, you will usually find a bypass diode. Understanding the Basics of Solar Panels, 2. Repeat for other PV modules you want to add to the series. If you connect the positive and negative terminals incorrectly, you'll face reduced efficiency, potential equipment damage, or even safety hazards. We will also show you how to check solar panel polarity, and how to connect a solar panel to a battery.
