“…The Figure 6 (b) clearly shows that if solar cell temperature increases from 20 to 80°C, the power output is reduced from 4800 W to 3200 W since increased module temperature increases the resistivity of semiconductor material and also enhances the heat loss in the atmosphere by convection and radiation 26,27) , 28) , 29), 30) . It can be seen from Figure 6 (a) that if the cell temperature increased from 20°C to 80°C the short circuit variation was negligible, even a little bit of increment seen in short circuit current due to increased temperature of solar cell material the same results also verified in 31) . The variation of cell temperature from 20°C to 80°C has an immense impact on the open-circuit voltage, it is reduced from 30 V to 20 V, as seen in Figures 6 (a), (b) 28), 31) .…”

“…Figure 7 (a) and (b) represent the impact of solar flux on the output responses. Figure 7 (a) shows that increased solar flux from 400 W/m 2 to 1000 W/m 2 enhanced the short circuit current from 5.5 to 9.1 amp but had a Negligible effect on open-circuit voltage 31) . Figure 7 (b) shows that if solar flux increased from 400 W/m 2 to 1000 W/m 2, the power output of the PV module enhanced from 2500 W to 4890 W.…”

In this paper, a 335 W solar panel with a centrifugal pump combined system was simulated in MATLAB Simulink 2018 with fuzzy logic-based MPPT, and the voltage, current, power, and discharge four output responses were determined at different values of solar flux, module temperature, and atmospheric temperature. Further, the output responses voltage, current, power output, and discharge data have been optimized in Response Surface Methodology (RSM). The output data of RSM and MATLAB Simulink is used to determine the solar pump's theoretical performance and overall efficiency. Finally, the RSM-optimized results of solar pumps are validated with the experimental results of the solar pump. The experimental setup consists of 15 panels of 335 W power and a 5 hp submersible pump operated by an AC motor. The experimental data were collected from 15/01/2020 to 15/12/2020. The optimization of the solar pump by the three most important variables solar flux, module temperature, and the atmosphere temperature is very new and unique since the selected input variables maximize the overall performance of the solar pump.

“…photovoltaics propelling scheme based on the induction engines is maintenance-free, reliable, and rugged with enhanced efficacy and provides potentials for control approaches contrasted to DC engines. E. Salilih, Y. Birhane, and S. Arshi in [15] have done a detailed evaluation of AC and DC engines utilized in photovoltaics propelling that indicate that the vibrant and efficient execution of permanent electromagnet DC engines is better compared to AC single-stage induction engine. The researchers also evaluated the execution features of brushes asynchronous reluctance engine governed by photovoltaic motors considering the different dimensions of insulations to propose a level and control method meant to maintain engine voltages.…”

Due to the evident shortfalls in the high costs of diesel and current, the requirements of pumping for agricultural and aqua supply have been affected. In that regard, utilizing solar energy to pump aqua is a potential technology for diesel-driven and conventional propelling structures. Propelling aqua using solar energy is done using photovoltaics techniques that transform energy from the sun into useful power meant to operate AC or DC engine-driven hydraulic ram. This research contribution provides a critical evaluation of the solar propelling technology e.g. Maximum Power-Point Trackers (MPPTs) and is based on economic viabilities of solar photovoltaics techniques and schemes, execution evaluation, photovoltaics generator degradation, and optimum sizing that distributes power to the electropumps. This analysis also relates to environmental and economic aspects, advanced Photovoltaics materials, and potential enhancements. Updates regarding the present condition and usage of solar H2O propelling technologies have also been focusing in this analysis.

“…Modi [27] provided a number of practical recommendations for small-holder farmers in a developing country based on a case study conducted in Senegal, including benefits from bulk procurement, logistics, transaction costs and interconnectivity to the grid. Dedicated software was also developed [28,29] as well as procedures for performance analysis and optimization [30][31][32]. The technical assessment also includes the manufacturing of the system, its efficiency, longevity and utilization [12,33], data requirements and monitoring [14,15].…”

Feasibility of Solar-Powered Groundwater Pumping Systems in Rural Areas of Greater Giyani Municipality (Limpopo, South Africa)

et al. 2023

Rural areas in Limpopo Province (South Africa) are in urgent need of interventions for safe and secure water supply to adapt to climatic changes and the increased frequency of droughts. A feasibility study was conducted for the adoption of solar-powered groundwater pumping systems and Multiple Water Use Services (MUS) in Greater Giyani Municipality (Limpopo). Stakeholder engagement, geotechnical data and socio-economic information were used in the feasibility study. The Solar Powered Irrigation Systems (SPIS) tool (GIZ and FAO, 2021) was used to design solar-powered shallow groundwater pumping systems at nine case study sites: four villages (water supply for domestic use) and five small-scale farms. Given the technical design configurations, peak water requirements ranged from 28.8 to 58.9 m3/d, peak power requirements from 1.2 to 3.4 kWp and required solar panel surface areas from 8.0 to 22.3 m2. Viable financial mechanisms for the operation and maintenance of MUS are leasing, cooperatives, informal saving groups and pay-per-use. The adoption of the technology appears to be financially and technically viable to augment the water supply. However, groundwater levels will have to be monitored and water purification plants for drinking water will have to be established to ensure long-term sustainability.
