Analysis of Dust Properties and Deposition Loss in Mono and Poly Crystalline Photovoltaic Modules in Southern Rajasthan
Manoj Lakhan [2] | Ram Kumar Mathur [2]
Abstract: Among all the renewable energy conversion technologies available on this earth, solar photovoltaic system is very important. The conversion of solar energy into electrical energy depends on the intensity of radiation coming from the sun, its spectrum, optical and electrical properties of the material used in making solar cells, geographical, atmospheric conditions of a particular place and compatibility with electronic devices etc. Except radiation and temperature in the atmosphere, dust makes radical change in the characteristics of solar panel properties. As dust accumulates on solar panels, their performance decreases and electrical power is reduced. The effect of dust on solar panels has been studied for the last several years, but at every site, the effect of dust on the properties of solar panels is unique and detrimental. Dust accumulation depends on the geographical and atmospheric conditions of the place, the origin of resources of dust at a particular place, wind speed, wind direction, chemical composition, humidity, temperature, rain and dust generation pattern etc. In this paper, chemical composition of dust, presence of various pollutants, its morphological study using SEM EDX technique has been done. Although the impact of dust deposition on the execution of sun powered panels has already been investigated by researchers but comparative study for two different and popular technologies; mono - crystalline and poly - crystalline in particularly Southern Rajasthan region which have not been addressed. Therefore in this work, dust mechanism and their effect on the performance has been analyzed and examined. To understand how dust impacts solar cell efficiency, we use scanning electron microscopy (SEM) and XRD techniques. The findings demonstrated that dust accumulation significantly affects solar cell efficiency. There was an average 14% drop in power output from poly - crystalline modules and an 18% drop from mono - crystalline ones. We also investigate that there is 3.45% decrease in efficiency for mono - crystalline module and 2.97% decrease in efficiency of poly - crystalline module. The results also show loss of power and efficiency is greater and higher in mono - crystalline module as compared to poly - crystalline solar module. This research illustrates how dust affects the output of photovoltaic modules that use sunlight for power generation. We compare mono - crystalline and poly - crystalline solar modules throughout several research locations, and we go over some solutions for cleaning the panels so they work better and can produce more electricity when the dust comes in performance domain.
