Optimization and economic evaluation of the systems of photovoltaic pumping in the areas of the South od Algeria : Case of Adrar

الملخص EN

In the areas isolated from the Algerian south, water and the ground can often be found, but the means necessary to pump water are often the primary constraint.

Considering the increase in the population and her sedentarisation, the mechanized techniques of irrigation and drinking water become increasingly significant to satisfy the enormous foreseeable request. The projects of photovoltaic energy in particular for the irrigation are still considered too expensive for these areas considered poor and stripped.

More especially as one of the characteristics of the systems of photovoltaic energy is that they can function with vacuum in most of the year, and it would then be necessary to identify other uses to return of such financially viable projects.

Such uses will be inevitably interesting by their contributions to the reduction of emission CO2 since they avoid the recourse to fossil energies.

The objective of this article is to make an optimization of the dimensioning of the system by a numerical method and an analysis of the effectiveness and cost over the life cycle of technologies of solar pumping in the area of Adrar.

It aims at considering the cost of meter-cubic of the water pumped according to the total head including the costs of the system, the costs of operations and maintenance, and other costs recurring.

This work should allow: 1- To estimate the reduction of the Gas emissions for Purpose of Greenhouse by the use of the systems of renewable energy such as photovoltaic solar energy, 2- To analyze the costs over the life cycle of technologies of pumping of the water, expressed in cost / ms. 3- To identify the hydraulic mode in which the systems of photovoltaic pumping have the potential financial yields highest and most attractive.
