Cover Story: Photovoltaic (PV) power generation represents a glimmer of light in a world plagued by climate change. PV plants are spreading out in both industrial and customer applications, and diagnostics tools are desired today more than ever. In this paper, EMPHASIS is proposed as a fault detection method that, for the first time, accurately predicts the cell-level generated power without the need for interrupting the energy production of the PV plant. The approach is based on a power balance equation applied to temperature maps—like those taken by drones—and promptly detects even minimal malfunctioning, evaluating the effects on energy production.
