ANEEL’s normative resolution Nº 482, from April 17 of 2012, made it possible for the consumer to generate their own electric power using renewable sources. The breakthrough coming from this resolution is the electric power compensation system that allows reducing the power’s expenses by converting the energy surplus generated by the photovoltaic system into energy credit to be used later. This final paper shows the sizing, according to the literature, of a grid connected photovoltaic microgeneration system for a type B client, wich has a voltage supply of up to 2.3 kV, grid-connected, and compare the results to computer simulations using the PVsyst software for situations with and without shading. Even assuming a modest performance ratio of 0.75, the average value of the suggested interval by the literature, the three designed systems where satisfied by a configuration of one string of nine 335 Wp photovoltaic panels connected in series, and a 3 kW single phase inversor. Compared to the manual approach, the simulation when there are no losses caused by shading have a 7% increase in the energy injected into the grid annually, and a 5.23% increase when there are losses caused by shading. Therefore, making the software simulation using PVsyst an interesting and viable solution, regarding the results.
