The improvement of the conversion efficiency of the photovoltaic panels, the efficiency of the inverters for connection to the electrical grid, and the dynamism of the distribution systems have had a direct impact on how energy is being generated in the residential, industrial, commercial, and transport sectors. This article shows an experimental study related to the analysis of a Building Integrated Photovoltaic (BIPV) system and its performance. A monitoring process was applied during three years to evaluate the energy production, CO2 emissions and economical savings. The paper presents the energy performance results of a 9.5 kW BIPV system installed in the El Paso residential area, located in Colombia (in the city of Girardot, at 74.7799 longitude and 4.3828 latitude). The main results during the first 3 years of monitoring (March 2019-March 2022) show that the average energy generation of the system has been 9,910.5 kWh/year; the environmental impact has been 3,645.38 kgCO(2)-equ. for the first three years of operation and the economic savings by generating clean energy have been 4,776.24 USD.
