Providing universal access to electricity is a priority worldwide. Renewable Energy Sources (RES) play an important role in the supply of energy to rural and remote areas, where grid electricity is not available, or the cost of the grid extension is excessively. Isolated communities in the Amazon region of Ecuador are frequently far away from each other, formed by scattered housing, exhibit very low population density, and are surrounded by dense vegetation. Supplying such communities is typically done through small paths, fluvial access, and in few cases through small planes. Therefore, implementing transmission and distribution lines for supplying energy is costly and harmful to the environment. Hence, the use of RES represents a crucial opportunity for power generation purposes. Photovoltaic Home Systems (PVHS) are typically used to provide electricity to the dwellings in off-grid rural communities. However, Centralized Photovoltaic Systems (CPVS) with their own low voltage distribution network (LVDN) is also being considered as an alternative for rural electrification. This thesis presents a comprehensive review on the use of RES for electricity, by providing the main features of this technology, classification, and schematic diagrams of hybrid systems (HS) in order to satisfy the energy demand for a single or an entire group of households in rural areas. This research also evaluates the electrical supply through PVHS and through a CPVS to provide energy to the rural community of Yuwints in the Ecuadorian Amazon. The most suitable system is selected after a comparison of the Net Present Cost (NPC) of various renewables system e.g. PV-Battery systems, Wind-battery systems, PV-Wind-battery systems, etc. The techno economic analysis is carried out through the microgrid optimization software Homer Energy. The result of the present study proposes the CPVS as the best option for the electrical supply of the community, allowing a full coverage of the load and guaranteeing a safe operation of the system
