This work presents the feasibility study and the project for a centralized 5 MWp solar installation with the aim of generating energy and injecting it into the grid. This installation is located in Chelva, Valencian Community, Spain. The first chapters are intended to introduce all the concepts for understanding the results of the thesis by presenting the state of the art of the photovoltaic sector. The main topics are therefore renewable energy, photovoltaic solar energy, module technologies, the inverter and other elements of an installation, from cables to protections. After these chapters, the heart of the project deals with arguments of the design choices.
