在我们这个时代，似乎没有人能怀疑水和能源对人类需求的重要性。随着技术的进步，对能源的需求不会停止增长。在使用传统资源往往非常昂贵的偏远地区，能源问题更加敏感。事实上，由于燃料的运输和柴油发动机的日常维护等一些限制因素，必须为这类场址寻找一种基本的替代能源。夏天有必要寻找替代能源的其他资源。可再生能源，如光伏能源、风能或水力，代表了一种卓越的替代解决方案，它们在我们的生活中越来越多地被使用，尤其是在美国拥有世界上最高的太阳能层之一的情况下。撒哈拉沙漠的日照时间可达3900小时/年。在1m2的水平面上每日获取的能量约为5kWh，即南方草地为2263kWh/m2/年。由于在干旱半干旱地区地下水势不太大，因此光伏能源抽水利用很好地适应了干旱半干旱地区的大部分地区。另一个非常重要的巧合是，支持使用这种类型的能源抽水，对水的需求，特别是在农业中，在炎热和干燥的天气中达到最大，而这恰恰是人们可以获得最大太阳能的时刻。目标是概述抽水光伏系统的一般组成，以及使当前泵站的尺寸成为可能的理论元素。
In our days, it seems to us that nobody can suspect it on the importance of water and energy for the human needs. With technological advances, the energy need does not cease increasing. This problem of energy is even more sensitive in the isolated sites where the use of the traditional resources proves often very expensive. Indeed, several constraints, like the transport of fuel and the routine maintenances of the diesel engines, return the search for an essential alternative energy source for this type of sites. It summer necessary to seek other resources of energy of replacement. Renewable energies, like photovoltaic energy, wind or hydraulic, represent a replacement solution par excellence and they are used more and more in our days more especially as the national territory has one of the solar layers highest with the world. The duration of insolation can reach the 3900 hours/year on the Sahara. The energy acquired daily on a horizontal surface of 1m2 is about 5kWh, that is to say meadows of 2263kWh/m2/year in the south of the country. The photovoltaic energy utilization for pumping of water is well adapted for more the share of the arid and semi-arid areas because of the existence in these areas of an underground hydraulic potential not very major. Another very important coincidence supports the use of this type of energy for the water pumping is that the demand for water, especially in agriculture, reached its maximum in hot weather and dryness where it is precisely the moment when one has access to the maximum of solar energy. The goal to see an outline on the general composition of a photovoltaic system of pumping, as well as the theoretical elements making it possible to dimension the current pumping stations.
