“…Figure 13 shows the normalized productions for each month of the year, as well as PV-array losses, system losses, and produced usable energy. This graph indicates that the highest energy is produced in the months of April-September, while the lowest is generated in the months of December-January (Hobus & Hegemann 2003;Renu et al 2017;Singh et al 2017;Najafi et al 2019;Chahartaghi & Nikzad 2021). This energy includes the energy generated by the PV panels as well as the energy necessary to pump the desired amount of treated wastewater for reuse in the Assa Oasis, which is anticipated to be 24 m 3 /day.…”

Treated wastewaters are an important alternative water supply for communities in dry climates all over the world. This study investigates using waste stabilization ponds (WSPs) to treat wastewater and the design of a solar photovoltaic pumping system to transfer the water to an Oasis in the Moroccan desert. The Oasis is currently about 5 ha in size and is irrigated with 24 m3/day of underground water. The wastewater is subjected to physicochemical and bacteriological analyses, also monitoring of operation, maintenance and loading rates of the WSPs for 12 months. To build a solar water pumping system, data on the system's components as well as local climatic data are obtained. The design optimization is done by simulation software PVsyst. WSPs provide reduced rates of BOD and fecal coliforms of 95 and 99%, respectively, with an average effluent concentration of 20 mg/l and 195 CFU. The exploitation of solar energy for pumping 24 m3/day requires five panels with a unit nominal power of 440 W for each panel and 2200 W for the entire system. This allows us to save about 1,500 kg of CO2 emissions per year, protect the region's fragile water resources and ensure the sustainability of the Oasis.

Renewable energy sources can contribute a lot to deliver reliable/resilient power to isolated communities and the world's sustainable energy future. In this paper, a novel DC microgrid system has been proposed for multipurpose use for isolated communities. The system taps the unused potential of the storage water to generate electricity. The system is configured to reduce complexity and cost by reducing the sensors in the solar pumping unit. Source, storage, and loads are the parts of an isolated system. The DC microgrid includes solar PV, battery, and domestic loads (All types' loads, that is, DC, AC, and dynamic loads). Incremental conductance algorithm has been chosen for the MPPT control, and sliding mode controls have been implemented to supply the sinusoidal supply for the AC loads. The system has included a battery unit to support the DC bus voltage and stable DC microgrid operation. The centrifugal pump has been taken to operate the pump as a turbine to extract the partial power potential from the water. The proposed system's MATLAB/Simulink model was designed for a village and presented as a case study.

The constant depletion of the existing energy sources and their environmental effects have generated interest in employing renewable energy sources to power water pumping systems, such as solar‐photovoltaic. The research addresses the optimal photovoltaic (PV) power output, solar radiation, operating head, and tilt angle for maximum solar energy used to capture more solar radiation for solar water pumping for irrigation purposes. In order to get the best performance from the solar PV water pump, such as discharge (Q), hydraulic power (PH), pump efficiency (ήp), and overall efficiency (ήo), the design of experiments‐based response surface methodology was implemented in this work. The data required for the RSM model were obtained from the experimental work performed at location 28.67° N, 77.21° E, Delhi, India. The experiments performed at five different ranges of input variables PV power output (4000, 4250, 4500, 4750, and 5000 W), Solar radiation (200, 350, 500, 650, and 800 W/m2), operating head (15, 20, 25, 30, and 35 m) Tilt angle (5°, 10°, 15°, 20°, and 25°). The best output parameters The best conditions for a solar PV water pump (16.8 m3/h discharge, 1.85 kW hydraulic power, 81.15% pump efficiency, and 16.12% overall efficiency) were discovered to be Po 5000 W, SA 260 W/m2, Head 35 m, and TA 19°. The predicted result was validated using an RSM‐based solution, and the error% was found to be within acceptable limits (>5%). The desirability 0.963 of the model was indicating the good solution.
