This article introduces an implementation of an insulated alternative energy system. The objective of the study is the analysis of energy generation in communities that are located in insulated areas. The study focuses on the development of a photovoltaic hybrid microgrid, with storage in stationary lead-acid batteries and energy from fuel cell. The photovoltaic hybrid microgrid must be sized to produce enough energy to supply to a community of houses. This study attempts to elaborate a standard computational simulation method using the Matlab® Platform, to size the system independent of region, but taking the impact of local global irradiance, air temperature, and the energetic demand into consideration. This simulation type allows an estimation of the photovoltaic power to be installed and the nominal battery capacity.
