“…A payback period that is shorter than the lifetime of a PV system is also required for investment. [ 28 ] The sensitivity analysis results revealed that capital costs, the feedback fund, and the daily power generating efficiency would be US$343 097 for every 1% of the total revenue (Figure S1). Furthermore, increasing the feedback fund to landowners by 1% would decrease the total revenue to US$100 000 ha –1 .…”

“…Because it has characteristics that differ significantly from those of typical refrigerants, carbon dioxide was chosen as the working fluid for this analysis. e low critical point of CO 2 (31.11 °C at 7.3 MPa) sets it apart from other refrigerants [4,5]. As shown in Figure 1, in the CO 2 phase diagram, the triple point is −56.6 °C and 0.52 MPa, whereas the saturation pressure is 3.5 MPa when the temperature is 0 °C.…”

This paper proposes a solar collector that utilizes supercritical CO2 as the working fluid to detect implicit water heating and boost the collector’s heating rate efficiency. Solar water heating system efficiency, cost, and environmental friendliness all depend on the working fluid used. CO2 is a possible natural refrigerant replacement. Even a little increase in temperature or pressure may have a big impact on the density of CO2 at the critical point. Because of this, solar heating can readily generate a spontaneous convection flow of supercritical carbon dioxide. The most basic collector characteristics, such as CO2 pressure and temperature, were determined by building and testing an experimental setup using a CO2-based solar collector. Due to solar radiation, liquid, gas, or supercritical CO2 pressures and temperatures change throughout the test. There was a 50% time average collector efficiency (ηcol) and a 30% heat recovery efficiency (ηRE). Solar thermal collectors based on supercritical CO2 have now been shown in this paper. Since the results show that even though the solar energy is low, the CO2 temperature, pressure, and supercritical stress remain constant, this is distinct from conventional liquid-based solar collectors.

The reduction of fossil fuel consumption is widely supported across various sectors. The agriculture sector presents a significant opportunity for sustainable solutions, electricity consumption is substantial for water pumping and irrigation. Solar power emerges as a promising alternative, particularly in the Middle East, renowned for its abundant solar resources. This study conducts a financial assessment integrating solar power into agricultural irrigation within the region. The proposed solar water system utilizes monocrystalline silicon photovoltaic modules to power a centrifugal pump, transferring water from 10-meter-deep wells to a 40 m3 surface tank. This system, with an initial investment cost of $25,058, was analyzed for economic feasibility in four locations: Bahtim (Egypt), Suwyban (United Arab Emirates), Ash Shibaniyah (Qatar), and Wadi Al Dawaserm (Saudi Arabia). Among these locations, the United Arab Emirate stands out for its substantial exposure to solar radiation, averaging 175 kWh/m2/day. The study emphasizes the importance of site-specific analysis over solely relying on a nation's economic status. Simulations conducted using the PVSYST program revealed that while the system performs less effectively in the Gulf regions due to the extreme temperatures, it achieves a high performance of 67.9% in Egypt. The system proves to be quite profitable in Egypt, with a payback period of 7.8 years and a net present value of $7175.37. The successful implementation of this solution fosters collaboration between stakeholders, decision-makers, and Egyptian authorities, collectively contributing to environmental protection by transitioning agriculture away from fossil fuel reliance.
