Solar tracking systems which can track the Sun movement can increase the power generation rate by maximizing the surface area of the solar panels that are exposed to the sunlight. By utilizing a solar tracker, the number of solar panels needed to generate the same amount of electrical energy will be significantly lower. In general, solar tracking systems are classified as single-axis solar tracking systems and dual-axis solar tracking systems. Several researchers had conducted both simulation and experimental work to compare and evaluate the performance of solar tracking systems against static solar panels systems, as well as between different solar tracking system mechanisms. General agreements among the researchers are that the performance of solar tracking systems is always exceeding that of static solar panels. Some researchers also conducted studies on how the weather conditions affect the performance of solar panels, and they concluded that the systems with tracking mechanisms are more resilient toward a variation of weather conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
