New graphical interface for Sizing PV systems

Abstract

The objective of this work is to carry out a sizing program of the photovoltaic system isolated from the grid by determining the size of the subsystems that make up the photovoltaic generator, the batteries, the charge regulator and the transformers... etc. This depends on the energy consumed by the total loads, the average annual solar irradiation, and the characteristics of the module and battery as inputs. This program was realized in the form of a graphical interface. We will present as an applied example the sizing of a house located in the south of Algeria, in particular in Ghardaïa, and this program has been broadcast on other sites.
