Manual electrical testing is the de facto method of inspecting PV systems. Known as IV Curve Tracing, the test is the current industry standard for inspecting and evaluating performance of a solar array. It is applied by trained,. . To complement and enhance manual electrical testing, the use of drone thermal imaging for PV inspections, also known as aerial thermography, is increasingly required in contracts for PV system commissioning and. .
