Solar photovoltaic (PV) systems harness sunlight to generate electricity, but several factors can contribute to energy losses. Such losses occur at different stages, from sunlight interception by solar panels to converting light into usable energy. One major source of loss is due to reflection of sunlight by panel surfaces and environmental factors like dust and dirt buildup. Another significant contributor is positioning inaccuracies of panels, which can reduce the amount of sunlight captured. Additionally, inefficiencies in the conversion process itself, known as conversion setbacks, also play a role. Understanding these various types of energy losses is crucial for optimizing PV system performance and maximizing the generation of clean electricity.
