The mathematical model of a single photovoltaic cell is used to built a numerical simulator of a residential solar generator. For the city of Santa Fe (Argentina), the following is analyzed: i) weather information on solar irradiances and ambient temperatures collected along the years 2008-2014; ii) the effect of the orientation assigned to the solar panels; and iii) the average household electricity consumption. It is proven that the annual energy uptake is maximized with an optimal panel inclination angle of 27°. Then, two solar generation systems suitable for residential users are proposed. The possibility of providing surplus electricity to the local distribution network under a net balance policy is analyzed. The results indicate that an installed capacity of 1,290 W (9 m2 of panels) can cover around 60% of the household annual electricity consumption. Moreover, the total energy coverage is achieved with an installed power of 2,150 W (15 m2 of panels).
