ENERGY ANALYSIS BY NUMERICAL SIMULATION FROM A FAMILY HOME.

Although methods of using renewable energy are knows all over the world (biomass, solar, wind, geothermal and hydro), so far only a relatively small fraction of the technical and economic potential of renewable energy is being used today. Investments in renewable energy and energy efficiency represent an important solution for environment and for economic crisis that Europe and the world at large are facing today. This paper presents the evaluation of renewable energy potential use for an independent house. The house uses a system comprising photovoltaic panels and solar panels. When there is surplus of electricity supplied from panels, this extra energy is stored in batteries to be used during not producing periods. We also use a solar thermal collector for thermal energy. The energy required for the home is used for household's appliances, for heating and for domestic hot water. Local real weather data are used in the modelling. [ABSTRACT FROM AUTHOR]
