Estudo comparativo da viabilidade económica entre os consumos na rede da EDM, no sistema fotovoltaico isolado e consumo híbrido (EDM e SFV) para uso residencial

Abstract

The present work intends to identify among the three consumption alternatives (consumption in the EDM electrical network, consumption in the autonomous photovoltaic system and consumption in the hybrid photovoltaic system) which behaves as economically viable for domestic consumption, in response to this concern there was need to have as an object of study two residences, one of low consumption in the Ndlavela neighborhood and high consumption in the Zona Verde neighborhood, both residences in Maputo province. Loads were also surveyed in each residence and sought to know the power of each energy consumer and how much time each charge consumes on average per day. With the help of the invoices that show the consumption history of each residence, a system was designed hybrid and autonomous photovoltaic system for each residence capable of responding to demand energy and then the costs of the three consumption options were simulated over a period of 25 years using the study of the economic viability of projects. With these aspects it can be concluded that consumption in EDM is economically viable until then in relation to consumption in different photovoltaic systems, be it autonomous or hybrid Bimodal, this is due to the high cost of the equipment that make up the system and this cost is felt more in the batteries as they must be dimensioned taking into account the days of autonomy (TRADUÇÃO NOSSA)
