Energy crisis is a cardinal issue which is being felt across the globe. According to studies, the world will run out of fossil fuels by the year 2112 if we continue using them at the current rate. A switch to renewable sources of energy can help drastically reduce greenhouse gas emissions and thus global warming. Power harvested from sunlight is one of the most widely used form of renewable energy with an immense scalability potential in tropical countries like India. A dual-axis solar tracker is currently the most efficient form of solar energy system but external factors such as relative terrain temperature, dust, humidity, and other pollutants still govern its efficiency in terms of power generation. Delhi-National Capital Region (NCR) of India is one of the most polluted regions in the world. This paper studies the impact of dust and pollutants on the efficiency of a Dual-axis solar tracker in the context of Delhi-NCR.
