At present, manual electrical testing (i.e. IV Curve Tracing) is the de-facto method of inspecting PV fields for identifying faulty cells, panels and string errors. Despite this being the industry standard for inspecting and evaluating the performance of a solar array, it can only be performed by trained, highly skilled technicians using handheld testing kits during only ideal environmental conditions. During the test, each string, or a row of panels scheduled to be tested, must be unplugged from the array and plugged into the manual electrical testing device. In addition to the issue of scale, technicians must manually interpret test results to determine the PV system performance. This takes hours or days for a small site, let alone for a large PV park.
