Nowadays, with the advantages of nanotechnology and solar radiation, the research of Solar Water Pump (SWP) production has become a trend. In this article, Prandtl–Eyring hybrid nanofluid (P-EHNF) is chosen as a working fluid in the SWP model for the production of SWP in a parabolic trough surface collector (PTSC) is investigated for the case of numerous viscous dissipation, heat radiations, heat source, and the entropy generation analysis. By using a well-established numerical scheme the group of equations in terms of energy and momentum have been handled that is called the Keller-box method. The velocity, temperature, and shear stress are briefly explained and displayed in tables and figures. Nusselt number and surface drag coefficient are also being taken into reflection for illustrating the numerical results. The first finding is the improvement in SWP production is generated by amplification in thermal radiation and thermal conductivity variables. A single nanofluid and hybrid nanofluid is very crucial to provide us the efficient heat energy sources. Further, the thermal efficiency of MoS2–Cu/EO than Cu–EO is between 3.3 and 4.4% The second finding is the addition of entropy is due to the increasing level of radiative flow, nanoparticles size, and Prandtl–Eyring variable.

“…Control of the growth medium in light, water, temperature, relative humidity, CO2 concentration, and ventilation provides optimal growing conditions for plants while improving crop yield and quality in greenhouse plant production. Many interrelated parameters can affect the environmental parameters in greenhouses, such as the size and location of the greenhouses, the type of cover material, the heat storage method, the amount and quality of the materials used, the type of cultivation, and the desired day and night temperature [1].…”

Due to increasing wars and global warming, the issue of providing the supply-demand balance in energy and food is becoming more important daily. When the issue of providing the electricity needed in modern greenhouses and consuming the energy where it is produced are evaluated together, rooftop applications in greenhouses become important. In this study, a photovoltaic system on a greenhouse in an area of 5031.6 m2 was modeled three-dimensionally using PVsyst software in north-south, and east-west orientations at 10°, 20° and 35° angles, and 6 different simulation studies were performed. By determining the cost of the greenhouse and above-greenhouse photovoltaic system to be constituted, an economic analysis study was performed at the point of OG single-term and OG double-term tariffs in the Energy Market Regulatory Authority (EPDK) tariff tables. As a result, the highest electricity production of the power plant was eventuated as 1579.2 MWh at 10° east-west orientation. In the case of the sale of electricity produced in the photovoltaic system installed above the greenhouse, it has been calculated that the OG single-term tariff brings 2 162 443.087 TL, and the OG double-term tariff 2 203 707.83 TL annual income. The lowest electricity generation was at 35° north-south orientation and was 1392.3 MWh. Based on this production value, it has been calculated that in the case of electricity sales, the OG monomial tariff brings an annual income of 1 894 757.401 TL, and the OG binomial tariff brings 1 930 914.04 TL.

“…It would also be profitable in the future if the prices of solar-PVs decreases and the cost of electricity increases. Kocar et al, 2018 examined the integration of solar technology in modern greenhouses. The authors reported that solar-PV systems can generate the electricity required in the greenhouses which could be 20-30% of their total energy demand.…”

Modern greenhouses can utilize renewable energy sources for covering their energy requirements and reducing their carbon footprint. Solar photovoltaics use for power generation is currently a reliable and cost-effective technology which is used in many applications. The purpose of the current work is to investigate the possibility of using solar photovoltaics in agricultural greenhouses in Greece and to assess their profitability compared with the profitability of their use in households. Semi-transparent and opaque photovoltaic cells can be used for electricity generation with the net-metering regulations covering all their annual electricity needs. Existing studies in various countries concerning their use in greenhouses have reported a payback period of the investments of 4-10 years. In Greece the cost of electricity in the agricultural sector is subsidized while economic incentives are offered regarding the use of this technology in greenhouses. Economic assessment of the investment of solar photovoltaics in greenhouses for a period of 25 years in Greece indicates payback periods of 7.2 and 14.4 years, depending on capital subsidies obtained, while positive net present values are achieved. Their use in households in Greece has a payback period of 10.4 years while the net present value is also positive. The current study indicates that the use of solar photovoltaics in modern greenhouses in Greece supported financially by the government according to the net-metering regulations is profitable, offering economic and environmental benefits to the farmers.
