Energy demand in remote area cannot be satisfied unless renewable energy based plants are locally installed. In order to be efficient, such projects should be sized on the basis of maximizing the renewable energies exploitation and meeting the consumer needs. In this context, this work proposes an optimum sizing algorithm of a standalone hybrid network composed of a wind generator, a photovoltaic panel, a lead acid-battery bank, and a water tank. The strategy consists of evaluating the renewable potentials (solar and wind). Obtained results are entered as inputs to established generators models in order to estimate the renewable generations. The optimal sizing of plant components is consequently developed using an iterative approach which computes the surface for which load profile meet the renewable productions. The approach validation is conducted for A PV/Wind/Battery based farm located in Sfax, Tunisia. Obtained results proved that the energetic need is covered and 0.5% of the generated energy is not used. Also a cost investigation confirmed that the plant becomes profitable after8 years of exploitation.
