Traditionally, the stand-alone hybrid electricity system has been viewed as an alternative renewable energy source. Therefore, the primary objective of this paper will be to look at a stand-alone hybrid system combination that will generate electricity, from a mix of renewable energy sources, to fulfill the electrical needs of an off-grid remote apartment in Istanbul, Turkey. Both solar photovoltaic systems and wind turbine will be considered as renewable energy sources. The paper will also demonstrate the residential demand in the HOMER PRO analysis and define the optimal off-grid system. The solution obtained from the studies shows that a hybrid combination of renewable energy and generators at an off-grid location can be a suitable alternative to grid extension (by considering the life cost cycle for 25 years). This is because it is both techno-economically viable and environmentally sound.
