Solar radiation, which is emitted by the sun, is required to properly operate photovoltaic cells and solar water pumps (SWP). A parabolic trough surface collector (PTSC) installation model was created to investigate the efficacy of SWP. The thermal transfer performance in SWP is evaluated thru the presence of warmth radiation and heat cause besides viscid dissipation. This evaluation is performed by measuring the thermal transmission proportion of the selected warmth transmission liquid in the PTSC, known as a hybrid nano-fluid. Entropy analysis of Oldroyd-B hybrid nano-fluid via modified Buongiorno's model was also tested. The functions of regulating parameters are quantitatively observed by using the Keller-box approach in MATLAB coding. Short terms define various parameters for tables in velocity, shear pressure and temperature, gravity, and Nusselt numbers. In the condition of thermal radiation and thermal conductivity at room temperature, the competence of SWP is proven to be enhanced. Unlike basic nano-fluids, hybrid nano-fluids are an excellent source of heat transfer. Additionally, with at least 22.56% and 35.01% magnitude, the thermal efficiency of AA7075–Ti–6Al–4 V/EO is higher than AA7075–EO.

“…Delivering SDG2 (Zero Hunger) relies on energy to power agricultural equipment for efficient and sustainable food production. Off-grid solar energy contributes to this Goal through solar irrigation which facilitates clean energy-based, year-round food cultivation (Rutibabara, 2018;FAO, 2015;Gasore et al, 2015;Nshimyumuremyi, 2015;Safari, 2010) and reducing the risk of food insecurity (Targets 2. 1, 2.3, 2.4).…”

Although photovoltaic (PV) Energy is a viable solution and clean energy source, it is an intermittent source and certainly needs energy storage, particularly in the case of off-grid applications. Batteries are normally used as the common energy storage, despite all their demerits. This paper presents a preliminary design and cost estimate of a potential candidate for energy storage applications, which is the PV-based Pumped-Hydro Energy Storage (PHES). The proposal is suited for application in rural and distant areas, where the public electric grid is not easily accessible. The basic idea is that the required load demand is fulfilled by PV panels during the day. During the periods of high insolation, the PV panels are also used to pump water to a 31-m height tank. Then, at night or in periods of low insolation the water is allowed to flow downwards operating a hydro generator. Based on the average expected load (irrigation and domestic) of distant locations in Egypt, the PV panels and reversible pumps have been sized together with other system components. A cost estimate has been done to compare batteries and PHES for the average lifetime of the two systems. The cost estimate revealed that the PHES would be economically viable after 23 years of service. The system can be easy to extend to a larger scale by adding more reversible pumps and PV panels.
