Abstract
Nowadays, water pumping systems powered by solar-cell generators are one of the most important applications. It’s a promising alternative to conventional electricity and diesel based pumping systems, especially for applications like community water supplies and irrigation. This study presents a monitored standalone photovoltaic solar direct pumping system using the Maximum Power Point Tracking (MPPT) algorithm to optimize the solar photovoltaic conversion efficiency. It was done at ISET-Rosso in Mauritania. The experimental setup based on Lorentz PS1200C-SJ8-5 pumping system consists of four photovoltaic (PV) panels, inverter PS1200, BLDC motor, centrifugal pump and a storage tank. The system has been monitored, in order to determine the relationship between: the DC power produced by the PV generator and the solar radiation; the water flow and the DC power and by then the relationship between the water flow and the solar radiation. The effect of ambient temperature and solar radiation on the PV panels was also done under Matlab/Simulink environment and compared to the experimental results. ©2019. CBIORE-IJRED.

Highlights
In Mauritania, there is much land but few people, in many places power is not easy to attain
The maximum power point tracker device allows the system to overcome the mismatch between the load characteristics and the maximum power operation point of the PV module
The monitoring of the weather condition shows that the most important radiation is in the month of May and the lowest is in the month of January
Summary
In Mauritania, there is much land but few people, in many places power is not easy to attain. To ensure the need of water, especially for rural areas and small communities, standalone photovoltaic pump systems have emerged as a result They are commonly used in domestic and livestock water supplies and small-scale irrigation systems, especially those employed for water and energy conservation such as low head drip irrigation systems. Their main advantages over combustion engine pumps include practically zero maintenance, a long useful life, no fuel required for operation, no air contamination, and straightforward installation. Their principal disadvantage is a high capital cost. The high cost of such application and the low return on investment are constraints that holdup the popularization of bringing independent photovoltaic pumping system to large rural area
