Thermal Analysis of The Effect of Hot Spots on Photovoltaic Solar Panels in Villanueva, Honduras

Year: 2026

Type: article

Abstract: This research analyzes the effect that hot spots can have on photovoltaic solar panels using infrared thermography techniques in Villanueva, Honduras. The main objective is to be able to estimate the loss of energy efficiency caused by hot spots, mostly caused by dirt, and to evaluate how their removal improves the performance of the photovoltaic system. The study uses a Fluke PTi120 thermal imaging camera to detect hot spots, which reflect thermal irregularities associated with dirt, and the performance of a set of panels is evaluated before and after cleaning. In addition, the analysis of total inverter generation data is used to correlate thermal variations with energy performance. The results highlight the influence of factors such as dirt type and weather conditions on panel efficiency. The research not only contributes to theoretical knowledge on predictive maintenance of solar systems but also offers practical recommendations to optimize cleaning strategies and extend the life of panels, reinforcing their economic viability and contribution to the sustainable energy transition.
