This article presents the results obtained after analysing the electric-energetic behaviour of a building in terms of solar energy harvesting system, load/discharge control, and energy support. This analysis is performed through of a simulation model implemented in MATLAB-Simulink (SimPowerSystem). The model is fed with both real data of instantaneous electrical consumption and photovoltaic generation. In addition to the behaviour of the building, the economic feasibility and the economic impact of the implementation are also evaluated. Specifically, the case study contemplates a building with high consumption and no possibility of hourly regulation that requires a reliable and robust storage energy system. The simulations were run with real local data of electric consumption, temperature, and solar irradiation, under both typical and worst weather conditions. Results show that it is possible to keep the building powered on without energetics gaps even in days with the lowest solar generation and the highest electricity consumption, therefore demonstrating the viability of the solution.
