A recent study conducted by Fahad Faraz Ahmad from the Renewable Energy and Energy Efficiency Research Group at the University of Sharjah has unveiled promising advancements in the deployment of solar-powered electric vehicle (EV) charging stations, particularly in dusty environments. Published in the journal “Transportation Research Interdisciplinary Perspectives,” this research addresses the growing demand for electric vehicle infrastructure as the e-mobility sector expands.
The project involved the establishment of an off-grid solar PV-powered EV charging station designed to meet the energy needs of electric vehicles while promoting sustainability through decarbonization, digitalization, and decentralization. The charging station, equipped with a 7.4 kWp solar PV system and a 34.56 kWh energy storage capacity, demonstrates a practical approach to integrating renewable energy into transportation.
One of the key findings of the study is the station’s ability to generate a total of 2,971.59 kWh of energy over the year, with 87.09% of that energy stored for later use. This efficient energy management allows the station to charge multiple vehicles simultaneously, with 83.87% of the energy consumed coming from the battery bank. The system operates at 24.58% of its full capacity, indicating potential for increased utilization if daily load demands rise.
However, the research also highlights a significant challenge: the impact of dust accumulation on solar panel performance. The study documented a notable decline in efficiency, with the performance ratio dropping from 77.92% to 27.30% over 218 days due to dust. After this initial degradation, the performance stabilized, suggesting that while dust accumulation is a critical issue, its rate diminishes once a thick layer has settled.
This research is particularly relevant for sectors involved in renewable energy, electric vehicles, and urban planning. As cities increasingly look to integrate sustainable transport solutions, the findings suggest both challenges and opportunities. The ability to optimize solar energy use in charging stations can lead to reduced operational costs and enhanced energy independence for municipalities and private operators alike.
“By elevating the daily load demand to 33 kWh, we can achieve full utilization of the solar resource,” Ahmad noted, emphasizing the potential for improved system performance with strategic planning.
The implications of this study are significant for businesses and governments aiming to expand EV infrastructure while minimizing environmental impact. As the transition to electric mobility accelerates, the insights gained from this research can guide the development of more resilient and efficient charging stations, paving the way for a greener future in transportation.
