Hot spots in solar panels can arise from shading, manufacturing defects, cell degradation, and electrical mismatches, leading to localized heating and potential performance issues. In a photovoltaic (PV) module, a hot spot describes an over proportional heating of a single solar cell or a cell part compared to the surrounding cells. It is a typical degradation mode in PV modules. As a result, the panel gets heated and overloaded, which leads to a short-circuit that lowers output efficiency overall while hastening material deterioration. Keep reading;. . Hot spots are a phenomenon that can affect the performance and longevity of solar panels. It's often due to uneven electricity flow caused by a malfunctioning or shaded cell.

To address these challenges, we propose a rapid detection method for hot spots in photovoltaic panels using deep convolutional neural networks, combined with unmanned aerial vehicle (UAV) inspection technology. Traditional approaches, such as those based on grayscale histogram processing, struggle with reflective noise in aerial infrared images. Other techniques. . Infrared thermography (IRT) is a technique used to diagnose Photovoltaic (PV) installations to detect sub-optimal conditions. The increase of PV installations in smart cities has generated the search for technology that improves the use of IRT, which requires irradiance conditions to be greater. . One critical maintenance challenge in photovoltaic installations is detecting hot spots, localized overheating defects in solar cells that drastically reduce efficiency and can lead to permanent damage.
