Utilization of Rooftop Solar Units to Generate Electricity and Hydrogen: A Technoeconomic Analysis

This study is aimed at scrutinizing the domestic solar energy potential for electricity and hydrogen production. Under the first scenario, it is sought to evaluate electricity generation for household purposes using RSUs (rooftop solar units). Then, under the second scenario, solar hydrogen producti...
