The station designed integrates a photovoltaic system to harness renewable energy, ensuring a sustainable and cost-effective charging solution. It accommodates both AC and DC fast charging options to meet diverse vehicle requirements. The design considers available space, energy generation potential, and financial feasibility to maximize efficiency and return on investment. A technical analysis of battery storage, power electronics, and system configuration is provided, along with a cost-benefit assessment. Simulation results confirm the station's ability to deliver stable power under varying conditions. With an estimated payback period of 2.8 years, this project demonstrates the economic and environmental advantages of solar-powered EV infrastructure, supporting the transition to clean transportation in Colombia.

INTRODUCTION Greenhouse gas concentrations in the atmosphere are steadily rising due to human activities, significantly impacting the climate system [1]–[3]. Key contributors include industrial production processes and fuel combustion, which generate emissions that accelerate climate change. The widespread use of electronic devices such as smartphones, computers, and televisions has significantly increased energy consumption and carbon emissions, reporting a 53% rise in greenhouse gas emissions from electronic devices and e-waste between 2014 and 2020, further accelerating global warming and its severe environmental consequences [4], [5]. Combustion engine vehicles are a significant source of pollution, emitting carbon dioxide into the atmosphere [6], [7]. Alongside other human activities, these emissions intensify the greenhouse effect, leading to rising global temperatures, extreme weather conditions, and severe environmental degradation [8], [9]. A shift to cleaner energy sources such as solar, wind, and hydroelectric power is essential. Equally important is promoting sustainable consumption habits, such as improving energy efficiency and reducing waste, to lower carbon footprints. The development and widespread adoption of eco-friendly transportation solutions, including electric vehicles and improved public transit systems, will further reduce emissions. Governments, industries, and individuals must prioritize policies that accelerate clean energy adoption and invest in carbon-neutral technologies. By taking proactive steps, like ending fossil fuel subsidies and expanding renewable energy grids, society can mitigate climate change and work toward a more sustainable and resilient planet [10], [11].
