“…Despite variations in location, weather data, system dimensions and equipment costs along with their impact on energy costs, the information in Table 5 provides valuable insights into the feasibility of the proposed system. The data reveal promising cost figures, particularly in reference to the comparably lower costs of systems (Habib et al, 2023;Garcia et al, 2022), attributed to their larger system sizes compared to the smaller scale of the proposed system. Anticipations suggest that costs will further decrease as the system size increases.…”

This study presents and assesses the novelty of a cutting‐edge solar‐powered automated irrigation system that incorporates a single‐axis solar tracker. The research entails the meticulous development of a prototype, followed by comprehensive experimental scrutiny spanning 3 days, from 8:00 AM to 6:00 PM. In a unique approach, we benchmark the findings against previous research endeavours, highlighting the transformative potential of our innovative design.Our innovative system harnesses a singular‐axis solar tracking mechanism alongside moisture sensors and a water pump relay module, resulting in the creation of an autonomous irrigation system perpetually powered by solar energy. The results are noteworthy, showcasing the capability of a solar panel equipped with single‐axis tracking to significantly boost photovoltaic output power. This configuration attains a remarkable 65% increase in total output power and a substantial improvement over the modest 52%–53% performance of fixed solar panels. This substantial divergence translates to a noteworthy 12%–13% difference in efficacy, underscoring the pioneering nature of our research.The zenith of power output, ranging between 3.16 and 3.68 W, transpires from noon to 2:00 PM, further illustrating the system's viability. The integrated water pump exhibits commendable efficiency, attaining levels as high as 75%. This revelation underscores the transformative potential of automated irrigation systems endowed with single‐axis solar tracking technology, auguring amplified system performance and heralding a new era of sustainable agricultural practices.

“…In addition, HOMER was used to optimize hydro systems with hydropower and photovoltaic plants in Lisbon (Portugal) [28]. The authors of [29] developed an optimized methodology using simulated annealing for hybrid systems involving photovoltaic and micro-hydropower systems with pumps as turbines (PATs), achieving an annual reduction of 2838 tons of CO 2 emissions and 553 MWh of energy generated from non-renewable sources in Spanish irrigation systems. The feasibility of similar systems in remote cities, such as the Bahamas, was investigated in a case study by [30].…”

The world’s water infrastructures suffer from inefficiencies, such as high energy consumption and water losses due to inadequate management practices and feeble pressure regulation, leading to frequent water and energy losses. This strains vital water and energy resources, especially in the face of the worsening challenges of climate change and population growth. A novel method is presented that integrates micro-hydropower plants, with pumps as turbines (PATs), in the water network in the city of Funchal. Sensitivity analyses evaluated the microgrid’s response to variations in the cost of energy components, showing favorable outcomes with positive net present value (NPV). PV solar and micro-wind turbines installed exclusively at the selected PRV sites within the Funchal hydro grid generate a combined 153 and 55 MWh/year, respectively, supplementing the 406 MWh/year generated by PATs. It should be noted that PATs consistently have the lowest cost of electricity (LCOE), confirming their economic viability and efficiency across different scenarios, even after accounting for reductions in alternative energy sources and grid infrastructure costs.

“…Their latest and most popular use is in ponds that are in intensive cultivation areas where water is used for irrigation purposes. In this case, the energy is either used for small pumps [23][24][25] or directly discharged to the grid.…”

In places where water and land are scarce it is vital to look for innovative solutions that can ensure water production for agricultural purposes. This study considers the treatment of water using desalination processes to meet the quality requirements needed for irrigation purposes in agriculture. As the water is stored in a pond, an inland floating photovoltaic (FPV) system is proposed to meet the desalination energy demand. This system would enable energy production without using additional land that could otherwise be used for agricultural purposes. The use of FPV technology also reduces water evaporation, thus avoiding unnecessary energy consumption. To generate enough electricity to treat 12,000 m3/day of water, using an electrodialysis reversal desalination plant, a 1.85 MWp FPV farm is proposed. The results indicate that this FPV farm would generate 3,005,828 kWh per year while avoiding the emission of 58,300 tons of CO2 and the evaporation of 159,950 m3 of water during its 25-year lifetime. Such systems allow higher renewable penetration in the energy mix and preserve the original use of the land.
