The present paper proposes the sizing of a PV system and his analysis to see how much impact it has on a company energy footprint and how much money they can save by not using electricity from the grid. For this project was used a simulator provided by SMA, showing that it’s possible to invest on a PV system and get the payback in a few years.engEnergy footprintPhotovoltaic SystemRenewable EnergySelf-consumptionjournal article10.34630/neutroaterra.vi23.4454
