To determine the grounding of solar panels effectively, a systematic approach involving various assessment techniques is essential. An elaborate discussion of visual inspection reveals its significance. . Measuring ground resistance using a multimeter is generally not as accurate as using specialized ground resistance testers, but it can provide a rough estimate. To isolate the fault, best practice is generally to start at the inverter level, then segment the system to narrow the tests to the combiner and eventually to the string level. It cannot be measured without inserting the electrode into the ground.
