Abstract :
Dust particle accumulation and dust intensity affect the performance of the PV module. Dust that settles on the outer surface of the solar cell glass blocks the incoming light so that the irradiation that can be converted into electrical energy is reduced. This is also directly proportional to the amount of dust that settles. This will affect the efficiency of the PV module because the output that should be produced by the PV module will be reduced. In this study, the author's purpose of conducting this research is to see the effect of dust on the efficiency of the PV module. In this study the sensitivity of the photovoltaic module to construction dust deposition was experimentally investigated under tropical climate conditions in Jakarta, Indonesia. . The selection of charcoal dust and gypsum dust as samples refers to the nature of each different dust so that the effect will be clearly visible later. Experimental measurements were carried out outdoors with various solar radiation intensities ranging from 90 W/m² to 1000 W/m². The results showed that the accumulation of dust on the photovoltaic module had a negative effect on power, current, and voltage. The maximum module efficiency is 8,29% for charcoal dust and 8,93% for gypsum dust with an average irradiation of 181.87 W/M² with a dust intensity of 75%. 7,66% for charcoal dust and 9,42% for gypsum dust with an average irradiation of 216.11 W/M² with a dust intensity of 50%. 7,07% for charcoal dust and 8,79% for gypsum dust with an average irradiation of 179.26 W/M² with an intensity of 25%. Charcoal dust is the most influential dust compared to gypsum dust. It also shows that the performance of the PV module deteriorates with increasing temperature due to heat dissipation caused by dust accumulation. So that the right treatment is obtained by performing regular maintenance when there is a 10% decrease in performance from it should or can overcome excess heat by using a heat shink.
