Obstruction

Photovoltaic panel obstruction test method

This report provides field procedures for testing PV arrays for ground faults, and for implementing high-resolution ground fault and arc fault detectors in existing and new PV system designs. PV ground faults have many potential causes, but most result from improper installation or damaged components. For example, a frayed wire. . MDs are used to detect faulty insulation in ungrounded designs. Inspect the panels visually for any physical damage, corrosion, or dirt accumulation, 2.
