N2 - As expected of most engineering systems, solar PV modules comes along with monitoring operational performances with standard testbeds and implementation of suitable maintenance policies for optimum system efficiency and effectiveness. Whilst significant publications concerned with the menace of dust deposition and soiling on PV installations in various Countries, and some authors went further to characterise the dust particles capable of causing failures, there is still no guarantee that uniform result will be obtained across all sections of a given Country. In this paper, the failure modes of solar PV modules installed in NCERD, located in South East Nigeria are delineated using non-destructive Infrared thermography approach. The relationships between current and voltage with irradiance and insolation as well as efficiencies were recorded pre and post maintenance actions and graphically displayed. The approach lead to the recommendation of maintenance policies that can improve the performance of the PV systems. The results show that Infrared thermography is a good means of detecting dust and soiling-induced failures in solar PV modules.
