“…Jones et al have evaluated the economics of a solar RO‐based greenhouse in which it has considered various scenarios, made up of four membrane types and two recovery rates. The study shows a 20% reduction in the CWR and 20% increase in the net profit for this integration, which is in line with those of Zarzo et al However, due to the high cost of the desalinated water, it is only suitable for locations with low salinities of the SFW and high added value crops.…”

“…The high cost of desalinated water can discourage investors from employing desalination technology for irrigating crops; however, this arrangement can increase the crop yield and quality and the net profit (up to 20%). There is also a huge reduction in the CWR (up to 30%) and less usage of fertilizers (up to 50%) …”

“…As an example, solar‐driven RO and electrodialysis need the pretreatment of the SFW while solar still, solar HDH, solar chimney, and solar‐based MSF and MED do not require a pretreatment process. Economies of scale is also important, where an increase in size results in a decrease in the WPC . Generally, direct solar desalinations, as well as solar‐driven RO and electrodialysis systems are suitable for small‐scale greenhouses, while solar thermal‐based MED, MSF, and RO are competitive candidates for medium‐ and large‐scale greenhouses.…”

“…On the other hand, employing solar‐driven desalinations for greenhouses is another promising approach to address the water‐energy‐food nexus. Such systems have been introduced in several countries around the world and discussed in multiple reports . These technologies can even help a greenhouse to be operated in rural areas, without access to the electricity grid, which is often referred to as off‐grid greenhouses.…”

Summary This paper is motivated by the crisis of freshwater in remote areas around the world and responds to the growing need for sustainable food production in arid lands. It focuses on utilizing solar energy to yield freshwater from the sea or brackish water with less environmental impacts, for greenhouses, which can produce sustainable food all over the year. The integration of various solar‐driven desalinations such as solar still, humidification‐dehumidification, reverse osmosis, electrodialysis, and multieffect and multistage flash with greenhouses are evaluated, for better sustainability towards greenization. The paper first discusses the specifications of solar‐driven desalinations and compares their advantages and limitations. Then, different types of greenhouses are introduced, and their total water requirement is discussed based on their locations, crop type, greenhouse technology, irrigation type, and environmental conditions, as well as their cooling and heating strategies. Later, the existing integration of solar‐driven desalinations with greenhouses are reviewed, and their advantages and limitations are deliberated. Finally, the paper discusses the criteria to be considered when selecting solar‐driven desalinations for greenhouses and presents a detailed comparison between the water production rate and cost as well as the energy consumption of these systems. In the end, the most appropriate combinations of solar‐driven desalinations with greenhouses are recommended based on their water requirement and production cost.

This investigation focused on the research undertaken on solar photovoltaic (PV) and solar thermal technologies for pumping water generally for irrigation of remote rural farms specifically considering the Sub-Saharan African region. Solar PV systems have been researched extensively for irrigation purposes due to the rise in Oil prices and the upscaling in commercialisation of PV technology. Based on the literature the most effective PV system is presented for the irrigation of a small scare remote rural farm with respect to the cost, pumping capacity and system efficiency. Similarly, solar thermal systems are reviewed and the most effective system described. Unlike PV technology, solar thermal technology for water pumping is lacking especially in small scale operations. However, with the possibility of local production, low investment cost, easy maintenance and lower carbon footprint, solar thermal water pumping technologies may be able to overcome the shortcomings of the PV technology that has stopped widespread use of the technology for irrigation applications. Taking into consideration recent developments in concentrated solar technologies using the Stirling engine, novel solar thermal water pumping systems may be developed. This review also highlighted the different methodologies such as modelling, used to investigate and optimise the performance of solar powered systems.

Agrovoltaics, also known as Agri‐PV or AV, is an innovative approach that entails the shared utilization of land for both the production of agricultural commodities and energy generation. This concept has gained immense popularity in recent times owing to its ability to boost income per unit of land area significantly. The scope of AV systems is quite extensive, as it encompasses solar energy converters and other renewable energy sources like bioenergy. Current strategies for agrovoltaic (AV) in agriculture are the outcome of the gradual development of agroecology and the integration of photovoltaic (PV) power supply into the grid. These approaches could lead to a nearly doubled income per unit area. Without on‐site power supply, reduced chemical fertilizers and pesticides, and on‐site yield processing, AV has the potential to revolutionize large‐scale unmanned precision agriculture and smart farming. These approaches might lead to significant changes in the logistics and value‐added production chain, thereby reducing agriculture's carbon footprint. In the future, it is possible to reduce the cost of AV technology by half by utilizing decommissioned solar panels in the technology and to delay the need for bulk PV recycling by several years. This review presents a different perspective to the common discourse on the topic, by giving special emphasis to the potential to further integrate AV into agriculture, which has the potential to facilitate the resolution of relevant legal disputes over the use of AV.
