Guía para el diseño de sistemas fotovoltaicos para el autoabastecimiento de unidades habitacionales : guía para el diseño de sistemas fotovoltaicos para el autoabastecimiento de unidades habitacionales.

Abstract

A methodology is presented to design photovoltaic systems for the self-sufficiency of housing units in order to contribute to the environment and sustainable development, avoiding the emission of carbon dioxide, which is the main responsible for global warming. The guide applies to the different strata of residential consumption in the concession area of Empresa Eléctrica Quito, considering the current regulatory framework about renewable energies and photovoltaic generation. To obtain horizontal global irradiation data, the database of the National Renewable Energy Laboratory (NREL) is used, a source used for the development of the Solar Map of Ecuador 2019, these data are corrected for the orientation and optimal inclination of the panel, then the overall performance of the installation is estimated and based on the estimates the plant factor and nominal power of the photovoltaic system is determined, finally the photovoltaic arrangement is determined. Based on the number of panels, inverters, cables, and protections obtained in the design, the necessary budget for the implementation of the system is presented. Through a microcredit in a bank, installments are established according to the loan and considering the passive rate issued by the Central Bank of Ecuador, the Net Present Value of the project is obtained, thus concluding on the feasibility of installing photovoltaic micropower plants in each stratum of residential consumption
