This paper explores the operational characteristics of a DC islanded microgrid engineered to produce green hydrogen, utilizing power sourced from a solar array complemented by an energy storage system. The model simulates a one-week evaluation period, incorporating comprehensive analyses of electrical, thermal liquid, and thermal gas domains. By examining the interactions between the solar array, energy storage, and electrolyzer, the study provides a detailed assessment of system performance under varying conditio...

This paper presents an in-depth analysis of a residential solar thermal system designed for domestic hot water (DHW) production in a single-family dwelling located in Mangalia, Romania. Positioned at a latitude of 43.894- and a longitude of 28.422-, Mangalia benefits from an annual global irradiation of 1403 kWh/m?, providing favorable conditions for solar energy utilization. The study evaluates the system's performance over the course of a year, focusing on energy consumption, solar fraction, and environmental be...

This paper presents a model for super-rapid charging stations powered by renewable energy sources and conducts an analysis of land suitability based on climatic parameters. Initially, data on temperature, solar radiation, and specific humidity were collected for three designated areas, followed by an examination of the variations in these values. Among the three cities, Cernavoda, Medgidia, and Ovidiu, two equal segments of approximately 30 kilometers each were established for the installation of photovoltaic pane...
