On-grid photovoltaic system for self-supply of energy in a housing development Sistema fotovoltaico On-Grid para el autoabastecimiento de energía en una urbanización

Abstract

The research evaluates the economic profitability of installing an electric power generation park using photovoltaic modules to self-supply the housing demand of the San Ignacio urbanization, Santo Domingo. The climatic conditions of the area were investigated, obtaining irradiation and temperature values by means of three PVsyst sources, averaged for a more realistic input to the software. The grid-connected photovoltaic system was designed using PVsyst, entering optimal tilt angles for the solar panels and the electrical demand of the array. System components were chosen and an overview of the distribution of the solar panels to the inverter up to the point of power injection was obtained. The economic evaluation of the project included details of component prices, initial investment costs, and maintenance for cleaning the PV modules. The project is viable due to the surplus energy injected into the conventional power grid, allowing for a medium-term payback of the investment and generating monetary gains for the owner. It is expected that this pilot project will encourage the implementation of distributed generation systems with renewable energies in housing developments.
