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. . Identifying the positive and negative poles of solar panels is essential for proper installation and efficiency in harnessing solar energy. Understanding the Basics of Solar Panels, 2. Always verify before connecting. .
