The rise of electric vehicles (EVs) has intensified the need for reliable, sustainable, and intelligent charging infrastructure. Solar-powered EV charging stations, enhanced with Internet of Things (IoT) capabilities, offer a promising solution to meet this growing demand. This paper presents a comprehensive review of IoT-enabled solar charging systems, focusing on their architecture, key components, communication protocols, and technological integration. While these systems provide numerous environmental and operational benefits, they also pose challenges in areas such as cybersecurity, energy optimization, and system complexity. By examining existing research and technological developments, this paper highlights the transformative potential of combining solar energy and IoT technologies in EV charging stations, promoting cleaner, more connected, and efficient mobility solutions.
