The present work presents the state of art revision for the Chilean legislation, norms and guides to carry out a photovoltaic installation at the Universidad del Bío-Bío. The Chilean solar potential with respect the rest of the world, high-lighting Chile as the world leader in solar resource availability, with the highest radiation rates, even bigger than countries as Germany, Spain, China, United States, which have a significant amount of photovoltaic (PV) energy installed. To attain a PV installation it is necessary to carry out an energy consumption study, considering the invoices of the electrical consumption and the daily consumption curve, in order to dimension the number of PV modules to be installed. In addition, the PV curves are studied to extract the maximum power from the PV modules by the use of algorithms capable to work into the whole system operating region, optimizing the energy injection to the grid and/or batteries. Finally, an economic study is presented where economics tools such as the Net Present Value (NPV) and Internal Rate of Return (IRR) are employed to show this project feasibility.
