Recent Developments of Solar Charge Controllers Technologies: A Bibliometric Study

A solar photovoltaic system is a renewable energy that depends on solar irradiance and ambient temperature. A solar charge controller is required to ensure the energy received by the photovoltaic cell or module is maximized at the output. This study presents the first bibliometric analysis based on a thorough evaluation of the most frequently cited articles on the solar charge controller to forecast future trends and applications. This paper performs a statistical analysis using the Scopus database and extracts the 100 most cited papers. It has been illustrated that the solar charge controller literature expanded swiftly from 2012 to 2023, with 2019 receiving the most publications and papers published in 2018 receiving more citations compared to works published in other years. In recent years, battery storage, electric vehicles, energy storage, controllers, photovoltaic systems, and power management systems have garnered great interest. The solar charge controller's functional evaluation and determination of the optimal renewable energy system might boost its potential. Our analysis of highly cited articles on solar charge controllers emphasizes a selection of features, including control methods and systems, issues, challenges to establishing current constraints, research gaps, and the need to find solutions and resolve problems. Every aspect of the features of this overview is anticipated to contribute to an upsurge through the invention of advanced solar charge controllers and control methods for future photovoltaic systems.
