Literature review:
In the realm of sustainable energy solutions, the integration of solar energy systems with
electric vehicle (EV) charging infrastructure stands as a pivotal endeavor. Over recent years,
researchers and industry experts have delved into this intersection to address both the
challenges and opportunities inherent in such integration. This literature review aims to
synthesize the findings, compare methodologies, and highlight emerging trends in this
burgeoning field.
Authors have articulated various perspectives on the challenges posed by the integration of
