A Technical and Economical Study of a Photovoltaic System Installed on the Rooftop of a Public Building

The rooftops of industry, business and public buildings have been good options for the installation of photovoltaic systems. These systems can contribute to the reduction of energy consumption and energy losses in the buildings, as well as to relieve the transmission circuits. This research work presents a technical and economical study of a photovoltaic system installed on the rooftop of a government building. The analysis methodology applied to this specific case is also presented. Calculations were made to obtain the system’s potential for photovoltaic power generation, as well as the economic feasibility indicators based on the project’s lifetime, in order to inform investment decisions.
