PV/Batteries sizing under multi criteria consideration

Electrification of isolated area is commonly ensured by autonomous power installation including renewable energy sources. Many software tools are available to size such installations. These tools refer to the daily energy need and the site global renewable potential which leads to inaccurate and wasteful sizing. This paper presents an alternative tool based on the energy consumption and the daily loads profile to compute the size of a standalone PV/Batteries system installed in an isolated chalet in Sfax, Tunisia. Obtained results are compared to those provided by PVsyst sizing tool to confirm the proposed algorithm effectiveness. In fact, although the slight high initial cost provided by the algorithm sizing, a profit of 55% in yearly charges is offered by the proposed sizing tool.
