This manuscript presents the design of a solar-powered electric vehicle (EV) charging station in Villavicencio, Colombia, aimed at reducing reliance on the utility grid, lowering energy costs, and minimizing environmental impact. 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 stations 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.

Results obtained show that designing an electric vehicle (EV) charging station requires selecting the appropriate AC or DC charging infrastructure.AC charging, though slower, remains the primary method in Colombia, while DC fast charging reduces charging time to under two hours, which is an important result.This means that future stations should prioritize DC charging to meet increasing demand, but AC chargers must still be included to accommodate existing vehicles.A hybrid charging station ensures accessibility and supports the transition to faster, more efficient charging solutions.The photovoltaic systems efficiency depends on available installation space and shading effects.The selected system requires 1,200 m² to install 260 solar panels, generating 184.47 kWₚ, which is an important finding achieved in this project.Proper panel arrangement minimizes shading losses and maximizes solar energy output.Limited space may reduce the number of panels and affect power generation, emphasizing the need for optimal site assessment and layout planning.

Berdasarkan penelitian ini, beberapa saran penelitian lanjutan dapat diajukan untuk meningkatkan efisiensi dan keberlanjutan stasiun pengisian kendaraan listrik tenaga surya. Pertama, penelitian lebih lanjut dapat dilakukan untuk mengoptimalkan penempatan panel surya dengan mempertimbangkan pola bayangan dinamis sepanjang hari dan musim, sehingga memaksimalkan penyerapan energi surya. Kedua, pengembangan sistem manajemen energi cerdas yang dapat memprediksi permintaan pengisian daya kendaraan listrik dan menyesuaikan output energi dari panel surya dan baterai penyimpanan secara otomatis dapat meningkatkan efisiensi operasional stasiun. Ketiga, eksplorasi integrasi teknologi Vehicle-to-Grid (V2G) memungkinkan kendaraan listrik untuk tidak hanya mengambil daya dari stasiun pengisian, tetapi juga menyalurkan daya kembali ke jaringan listrik saat dibutuhkan, sehingga meningkatkan stabilitas jaringan dan potensi pendapatan bagi pemilik kendaraan. Dengan menggabungkan ketiga saran ini, pengembangan stasiun pengisian kendaraan listrik tenaga surya dapat menjadi solusi energi yang lebih efisien, andal, dan berkelanjutan, mendukung transisi menuju transportasi bersih dan mengurangi ketergantungan pada sumber energi fosil.
