Economic and energy analysis of small capacity grid-connected hybrid photovoltaic-wind systems in Mexico

Abstract

The integration of renewable energies in the electric power system, as a solution to the growing demand for electricity in developing countries, has become a vital issue, such is the case of Mexico. The purpose of this work is the assessment of the economic and energy feasibility of a residential house grid-connected hybrid photovoltaic (PV)-wind system, in Mexico. The hybrid PV-wind system design is based on the existing renewable energy resources and considering a typical load profile. Also, an economic analysis is presented based on the two schemes approved for the sale of the surplus of the energy generated in Mexico: Net billing and net metering. The results obtained demonstrate the viability and profitability of the proposed small-size system. However, the results corroborate that government incentives are crucial to making the proposed system more attractive and affordable for residential users.
