Evaluación técnica y económica de la implementación de sistemas fotovoltaicos para la electrificación de radio bases remotas de CNT

Abstract

The technical study presents a methodology for the design of photovoltaic systems for powering CNT´s telecommunication stations in Ecuador remote areas instead the generator sets currently used as backup each site. The study is carried out to provide an economic evaluation considering the operation and maintenance savings generated by the photovoltaic systems in comparison with the generator sets; evaluating each project with economic indicator VAN and TIR and in the same way analyzing the cost of the kWh for each technology. The results obtained show that the use of photovoltaic systems are economically more feasible than the generator sets for CNT¨s remote sites, due to the low cost operation and maintenance cost generated by photovoltaic systems, in contrast to the costs generated by the generators. The evaluation of the cost of the energy generated by each system was also carried out, resulting in that for photovoltaic energy the average cost is 0.15 USD/kWh compared to the energy generated by the generators sets, which on average is 0,30 USD/kWh. Moreover, the change oh technology represents a benefit in favor of the environment due to the positive impact due to the reduction of emissions of approximately 2.63 kg of CO2 per liter of diesel used to generate electricity.
