Experimental techno-economic analysis of an autonomous photovoltaic system operating in Chocó

Despite of scientific efforts to evaluate economically the photovoltaic plants integrating the costs generated by the technical behavior of the system, few studies have demonstrated the behavior of the economic parameters from experimental data obtained from the photovoltaic plants in real-time oper...
