EFFECT OF HOT-SPOTTED CELL ON PV MODULE PERFORMANCE

In this paper, the effects of the hot-spotted cell on PV module were evaluated. The experimental observation was based on 100 kW PV array composed of 20 PV modules. It was found that an increasing number of hot-spotted solar cells in a PV module would likely increase its output power loss. It was also noticed that most of the PV modules affected by hot-spotted PV string are relatively affected by high-temperature levels, dust, and Partial shading due to trees or tall vegetation. Furthermore, the average performance ratio (PR) and degradation rate (DR) of all examined PV modules were analyzed
