“…In that context, solar water pumping appears as an attractive option for irrigation and drinking water as confirmed by some recent studies [6][7][8]. Chandel et al study the techno-economic performances of a direct coupled photovoltaic water pumping system with a case study of an old functional solar water pumping system in a western India location.…”

Background: The population in Burkina Faso is rapidly adopting irrigation to adapt to negative impacts of climate change like prolonged drought, rainfall variability and desertification. The solar water pumping systems (SWPS) could be an attractive option in view of climate change impacts, increasing diesel costs and grid electricity scarcity that the country suffers. However, due to high initial cost SWPS, population mainly uses diesel water pumps (DWPs). The main objective of this study is to assess the potential of microfinanced SWPS for irrigation in rural areas of Burkina Faso. Methods: Based on ground data collection and profitability analysis, this study investigates the best SWPS market segments for irrigation in rural areas of Burkina Faso. The case study of the village of Korsimoro was considered. Especially, the study is focused on the onion crop as it is the most cultivated crop in the area of study. Results: It was found that there are three main SWPS market segments in the area of study: market segment 1 which is that of farmers individually owning and using a DWP with rated power between 1.5 and 3 kW, market segment 2 which is composed of farmers individually owning a DWP of rated power ranging from 4 to 7.5 kW and market segment 3 which is that of farmers paying for pumping services offered by a pump owner in market segment 2. The study revealed that replacing polyvinyl chloride (PVC) water storage tank by DWPs to be used on cloudy days is profitable for all the market segments. The study showed also that at 9.5% interest charged on agricultural equipment, only SWPS for the market segments 2 and 3 can be fully financed through microloan without risk of long payback period. Conclusions: The results imply that more attention should be given to SWPS in the context of rural areas of Burkina Faso to enhance the productive use of energy and also mitigate the impacts of climate change on the environment. In addition, the study provides detailed information to farmers about how they can make more profitable their activities.

“…One of the advantages of diesel-powered, water pumping systems is that the installation is simple. Nevertheless, the disadvantage arises with the frequent need for maintenance of the equipment, constant fuel consumption, indiscriminate use of nonrenewable resources, and environmental pollution caused by exhaust gases [2]. On the other hand, the dry nature of Arequipa's climate constitutes a challenge for agriculture, one of the main activities of isolated rural zones.…”

In the present experimental study, a photovoltaic (PV)-powered system in continuous current (4 kW) for the pumping of water in an isolated, rural agricultural zone in Arequipa-Peru was analyzed. A meteorological station was installed in the studied zone, measuring solar radiation, temperature, relative humidity, and wind speed. The electrical and hydraulic parameters of the solar-pumping system (i.e., electric current, voltage, mass flow, and hydraulic pressure) were measured in order to evaluate the efficiency of the energy transformation processes. The results indicate that, during the year of 2017, the PV pumping system in direct current (DC) functions from 07 h 30 min to 15 h 30 min, during an average of 8 h a day. The PV array, hydraulic, and global efficiencies were evaluated. This allows for the interpretation of efficiency independent of solar irradiance. The efficiency of the PV array and global efficiency remained constant (11.5% f and 8.5%, respectively). The functioning interval of the PV array ranges from 880 W up to 3400 W, making evident the versatility of the system of generation and consumption in DC, which is able to function since solar irradiance is at least 200 W/m 2 , corresponding to 880 W of PV array power, 27 m of total dynamic head (TDH) and 2 kg/s of mass flow, and 70% hydraulic efficiency. With greater mass flows (6.3 kg/s), the PV array power was 3256 W with a hydraulic efficiency of 55%, a TDH of 30 m, and a peak solar irradiance of 1190 W/m 2 . When the whole system functions in DC, the efficiencies are superior to those of systems, which operate with DC/alternating current (AC) current inverters.

“…In this regard, the experience of the Regional Sahel Program, that installed 600 PV pumps to provide drinkable water to 1 million people, was particularly interesting because it developed exhaustive technical specifications and quality control procedures with remarkable results [23][24][25][26]. In parallel, new developments allowing standard frequency converters and centrifugal pumps to be used, reduced the cost and increased the reliability [27][28][29][30]. This long experience was limited to providing clean water to the population or small-scale irrigation systems with relatively lowpower PV systems typically between 500 Wp and 5 kWp.…”

The adaptation of the mature PV water-pumping technology to large power irrigation applications requires the problems associated to PV power intermittencies and matching PV production with the irrigation needs to be resolved. This paper presents the innovations developed, implemented and tested in a PV irrigation prototype installed in a real well at an Irrigator Community in Alicante, Spain. The innovations elimínate the intermittences due to passing clouds, reducing the PV power by 80% in just few seconds without batteries, just using control algorithms in the frequency converter, avoiding water hammers and overvoltages. A North-South horizontal axis tracker has been used to extend the number of hours of irrigation per day and to provide daily constant profiles of PV power during the irrigation period. Moreover, the use of this tracker allows the nominal power of the PV generator to be reduced by 45% as compared to a flxed structure for the same volume of water. The analysis of the economic feasibility of the prototype compared with the cost of grid electricity shows savings of 60%. This prototype has been operating in the South of Morocco delivering more than 235 m 3 /day for the last three years.
