Diseño de un sistema fotovoltaico residencial para movilidad eléctrica en una vivienda unifamiliar ubicada en la ciudad de Quito.

Abstract

Ecuador is a country with very varied climatic typologies that grant an excellent potential for the use of renewable energies. Giving way to the implementation of regulations that favor the use of clean energy such as solar, which currently seeks to mitigate the environmental impact resulting from the use of fossil fuels in the residential and transportation sectors. The objective of this work is to carry out the analysis of a PV system interconnected to the grid including electric mobility for a family of four in a single-family home located in Quito, La Vicentina sector. For this, the energy requirement of the house for domestic and mobility activities was determined, the data available on mobility in the Metropolitan District of Quito was analyzed (surveys and reports), and the main loads of electricity demand were determined within the home and the mobility of the average Quito to obtain the necessary load for the designated vehicle. The study presented below establishes five scenarios. These consider different energy requirements based on the type of cooking, water heating and electric mobility within the city. The system was simulated using the technical-economic software package System Adivsor Model. The result of this simulation provides the dimensioning of the PV system and the space required for its implementation. Subsequently, an economic viability analysis is carried out considering the costs of the main components of the PV system and the cost of electricity where it is evaluated with and without a tariff subsidy through indicators such as NPV, IRR, recovery period and cost-benefit ratio. It is observed that for scenario two in terms of energy requirement there is an economic feasibility of implementation, where the cost of electricity does not preside over the tariff subsidy. Finally, the rest of the scenarios are covered by their energy requirements, however they are not economically viable.
