DACF Dual-Use (Agrivoltaics) Dual-Use or (Agrivoltaic) Solar Installaons What is Dual-Use? • Dual use is the integraon of agricultural producon with a photovoltaic (PV) s stem. It allows for solar energ producon while maintaining agricultural acvies. • T picall it is considered the installaon of a solar arra that parall obstructs solar penetraon to crop producon (either forage land or crops). • Solar mounted on barns, greenhouses, or &oang on agricultural ponds ma also be considered dual- use operaons. Benefits of Dual-Use • Landowners diversif their incomes streams while connuing to produce agricultural products. • Protects against loss of producve farmland due to permanent solar development. • Provides a mar)eng opportunit to a sustainabilit -minded audience. • Required securit fencing doubles as an e,tra secure enclosure for livestoc). • Shaded soils ma retain more moisture and reduce water consumpon for some species of crops. • Provides relief for wor)ers and animals beneath the arra .

In Spain, despite being a country with enormous potential for this renewable energy source, little is being done to exploit it, and policies of recent years have even restricted its implementation. These factors constitute an obstacle, both for achieving environmental commitments and for socioeconomic development. This study proposes the installation of PV systems on greenhouses in southeast Spain, the location with the highest concentration of greenhouses in Europe. Following a sensitivity analysis, it is estimated that the utilization of this technology in the self-consumption scenario at farm level produces increased profitability for farms, which can range from 0.88% (worst scenario) to 52.78% (most favorable scenario).

Agrivoltaic systems are an approach that allows for both agricultural and electrical production on the same land area. These systems have the potential to reduced water demand and increase the overall water productivity of certain crops. We observed the microclimate and growth characteristics of Tomato plants (Solanum lycopersicon var. Legend) grown within three locations on an Agrivoltaic field (control, interrow, and below panels) and with two different irrigation treatments (full and deficit). Total crop yield was highest in the control fully irrigated areas a, b (88.42 kg/row, 68.13 kg/row), and decreased as shading increased, row full irrigated areas a, b had 53.59 kg/row, 32.76 kg/row, panel full irrigated areas a, b had (33.61 kg/row, 21.64 kg/row). Water productivity in the interrow deficit treatments was 53.98 kg/m3 greater than the control deficit, and 24.21 kg/m3 greater than the panel Citation: AL-agele, H.A.; Proctor, K.; deficit, respectively.

This is particularly important in densely populated developing and developed countries, where renewable energy development is becoming more important; how- ever, profitable farmland must be preserved. As emphasized in the Food-Energy-Water (FEW) nexus, AVS advancements should not only focus on energy management, but also agronomic management (crop and water management). Thus, we critically review the important factors that influence the decision of energy management (solar PV architecture) and agronomic management in AV systems. The outcomes show that solar PV architecture and agronomic management advancements are reliant on (1) solar radiation qualities in term of light intensity and photosynthetically activate radiation (PAR), (2) AVS categories such as energy-centric, agricultural-centric, and agricultural-energy-centric, Citation: Zainol Abidin, M.A.; Mahyuddin, M.N.; Mohd Zainuri, and (3) shareholder perspective (especially farmers). Next, several adjustments for crop selection and M.A.A. Solar Photovoltaic management are needed due to light limitation, microclimate condition beneath the solar structure, Architecture and Agronomic and solar structure constraints.

Among these, agrivoltaics is emerging as very promising for allowing benefits in the food–energy (and water) nexus. Demon- strative projects are developing worldwide, and experience with varied design solutions suitable for the scale up to commercial scale is being gathered based primarily on efficiency considerations; nevertheless, it is unquestionable that with the increase in the size, from the demonstration to the commercial scale, attention has to be paid to ecological impacts associated to specific design choices, and namely to those related to landscape transformation issues. This study reviews and analyzes the technological and spatial design options that have become available to date implementing a Citation: Toledo, C.; Scognamiglio, rigorous, comprehensive analysis based on the most updated knowledge in the field, and proposes a A.

  • Beauty of Agrivoltaic System Regarding Double Utilization of Same Piece of Land for Generation of Electricity & Food Production Dhyey D
    International Journal of Scientific & Engineering Research Volume 10, Issue 6, June-2019 118 ISSN 2229-5518 Beauty of Agrivoltaic System regarding double utilization of same piece of land for Generation of Electricity & Food Production Dhyey D. Mavani, P M Chauhan, Viral Joshi Abstract— In order to meet global energy demands with clean renewable energy such as with solar photovoltaic (PV) systems, large surface areas are needed because of the relatively diffuse nature of solar energy. Much of this demand can be matched with aggressive building integrated PV and rooftop PV, but the remainder can be met with land-based PV farms. Using large tracts of land for solar farms will increase competition for land resources as food production demand and energy demand are both growing and vie for the limited land resources. Land competition is exacerbated by the increasing population. These coupled land challenges can be ameliorated using the concept of agrivoltaics or co-developing the same area of land for both solar PV power as well as for conventional agriculture.A coupled simulation model is developed for PV production (PVSyst) and agricultural production (Simulateur mulTIdisciplinaire les Cultures Standard (STICS) crop model), to gauge the technical potential of scaling agrivoltaic systems. The results showed that the value of solar generated electricity coupled to shade-tolerant crop production created an over 30% increase in economic value from farms deploying agrivoltaic systems instead of conventional agriculture.Crop yield losses to be minimized and thus maintain crop price stability. In addition, this dual use of agricultural land can have a significant effect on national PV production.

  • Agrivoltaic in Chile – Integrative Solution to Use Efficiently Land For
    ISES Solar World Congress 2019 IEA SHC International Conference on Solar Heating and Cooling for Buildings and Industry 2019 Agrivoltaic in Chile – Integrative solution to use efficiently land for food and energy production and generating potential synergy effects shown by a pilot plant in Metropolitan region Patricia Gese1, Fernando Mancilla Martínez-Conde1, Gonzalo Ramírez-Sagner1, Frank Dinter1 1 Fraunhofer Chile Research – Center for Solar Technology, Santiago de Chile Abstract In Chile, one of the most vulnerable productive sectors, in the context of climate change, is agriculture. The country faces the risk of losing high-quality soil surface mainly by desertification, erosion, contamination and inappropriate agriculture practices. Risk of agricultural land losses constantly rises due to the increasing food and energy demand, as well as the use of land for human dwellings and industrial operations. In addition, the rapid growth of the energy sector is highlighted, where Chile has ambitious goals on expanding non-conventional renewable energies. Here, solar photovoltaics (PV) present high potential due to the high irradiation levels especially in the northern region of Chile. This, added to decreasing PV system costs, allow solar PV installations going south closer to the energy consumption poles. In the context of both trends, a system to combine agriculture with photovoltaics (APV) is presented as an inter- sectorial solution for food and energy production using the same land benefit from synergy effects like reduction of water evaporation and protection for crops, especially in arid/semi-arid zones. Additionally, first results of an APV pilot plant near Santiago of Chile are presented. Finally, conclusions are developed in addition to an outlook in order to provide a baseline of information for the usefulness of the concept in the country.
