DIMENSIONING AND ECONOMIC ANALYSIS OF A GRID-INDEPENDENT PV SYSTEM FOR A STANDARD HOUSING

Abstract: With the increasing population and industrialization, the need for electrical energy is increasing day by day. In order to meet the need, the use of renewable energy sources has come to the forefront especially in recent years. Among the renewable energy sources, solar energy technologies are the most appropriate solution to meet the individual energy needs. Photovoltaic (PV) systems that convert solar energy into electrical energy are separated as grid-dependent and grid-independent according to their connection type. Grid-independent PV systems are preferred when there is no network, frequent and long-term disconnection of the network, the transmission lines are not economical. In this study, economic analysis and dimensioning of the grid-independent photovoltaic system were conducted for a standard housing in the Turgutlu district of Manisa province. The analyses were performed in the Renewable Energy Laboratory supported by the MCBU BAP Unit. Life cycle cost (LCC), annual life cycle cost (ALCC), electricity cost (UCel) of the components used in this system were calculated. This model can be used to design and assess the economic feasibility of off-grid PV electrification in any geographical location of the world by sorting input data viz. solar insolation, cost of the conventional energy as well as the market prices of the off-grid PV components.
