In agrivoltaic systems with solar fixed panels, the provision of ecosystem services by agricultural productions could be compromised due to very large changes in plant microclimate. But we still do not know properly the changes in grasslands ecosystem services. On two sheep-grazed sites located in lowland (Braize, Br) and upland (Marmanhac, Ma) grasslands of central France, we studied for one year the direct effects of various shading conditions induced by solar fixed panels on abiotic variables (light, water and soil temperature) and on vegetation (daily growth height, forage quantity and quality, number of species). Under exclosure of grazing, three treatments per site were set up, control (without solar-panel influence), inter-rows (variable influence) and panel (full influence). The results showed that light was reduced by 93% on average over the year in the shade of the panels with a cooler soil temperature of 2.6°C on Ma and 3.4°C on Br compared to the control. However, the soil moisture response varied between sites, depending on the different seasonal rainfall events and on soil texture. This resulted in 2.6 (Ma) to 3.2 (Br) times faster daily height growth and better forage quality. However, annual biomass production and species number showed no difference between the control and the panel. Only the inter-row treatment, which receives variable shading conditions throughout the day and seasons, shows variable biomass responses across sites. Experimental work will continue for several years in order to parameterise models to simulate the ecosystem services of agrivoltaic parks over the long term.

The benefits deriving from the coexistence of energy production from a photovoltaic plant and crops growth on the same land have been investigated in Enel Green Power photovoltaic plant of Totana, in the semi-arid region of Murcia, in Spain. In this area, scarcity of water resources and high temperatures can have a major impact on production and agrivoltaic can be relevant for the potential benefits of shading on crops. Pepper “Bola”, aloe vera and thyme have been selected for their economic importance and adaptation to the conditions of the area. The results reported are related to the testing areas in the corridors between two modules rows and to the control area. For pepper, an increase of more than 60% in the agricultural yield and in fresh mean weight and of more than 30% for the fruits number have been observed in the corridors, with respect to the control area. For aloe and thyme in the corridor zone a higher plant biomass (more than 30% and 20%, respectively) has been recorded, compared to the control area. An increase of 11% in weight of the fresh biomass has also been detected for thyme in the corridor after about one year from the implementation. The results obtained in the first year have shown that the intermittent shade and microclimate generated by the photovoltaic panels in the corridor area could benefit pepper, aloe vera and thyme cultivation. These trials will continue in next crop cycles, to confirm the preliminary results.
西班牙穆尔西亚半干旱地区托塔纳的 Enel Green Power 光伏电站研究了光伏电站生产能源与农作物生长在同一片土地上共存所产生的效益。在这一地区，水资源匮乏和高温会对生产产生重大影响，而农业光伏发电可以为农作物带来遮阳的潜在好处。之所以选择 "博拉 "辣椒、芦荟和百里香，是因为它们具有重要的经济价值，并能适应该地区的条件。报告的结果与两个模块行之间走廊上的测试区和对照区有关。就辣椒而言，与对照区相比，走廊区的农业产量和平均鲜重增加了 60%以上，果实数量增加了 30%以上。与对照区相比，走廊区芦荟和百里香的植物生物量较高（分别超过 30% 和 20%）。在实施约一年后，走廊上的百里香的新鲜生物量也增加了 11%。第一年的结果表明，走廊区域光伏板产生的间歇性遮荫和小气候有利于辣椒、芦荟和百里香的种植。这些试验将在下一个作物周期继续进行，以确认初步结果。

We present a model and study investigating the potential power output of vertical bifacial solar panels on New Jersey farms. The simulation calculates instantaneous brightness and shading based on the position of the sun and adjacent rows of panels, and uses that to calculate current and voltage values. We explore different strategies to improve the power output further. Double-high modules, which use two panels stacked together, offer significant gains per acre with only a modest increase of inter-row shading. When bypass diodes and improved inverter wiring are also used, much of the losses due to shading are avoided, and the total power output per acre is nearly doubled. In a double high configuration it is advantageous to have the top and bottom modules on separate inverter strings.

Visual landscape impacts are of great importance when it comes to social acceptance measures of renewable energy. Although agrivoltaics seems to have higher acceptance values than other renewable energy infrastructures due to the dual land use approach, it is expected that they have a bigger visual impact on the landscape scenery than ground-mounted installations due to the increased land requirements and clearance heights. This article presents the development of a game-based visualisation approach using open-source software and open data (open government data) for visualising energy landscapes by creating large-scale interactive and immersive 3D visualisations. The results show that the use of open geodata and available open-source gaming technologies can be used to create comprehensive digital VR landscapes for assessing the visual impacts of agrivoltaics. Furthermore, the data-driven approach can provide additional indicators for evaluating planning scenarios and investigating the social acceptability due to renewable energy expansion.

Agrivoltaic systems (AVs) combine agricultural activities with the electricity production from photovoltaic (PV) panels constructed on the same area of land. Goetzberger and Zastrow[1] (1982) introduced the concept of AV but only more recently the increased environmental concerns and the economic and political frameworks have stimulated a growing interest in this technology. A critical issue, hampering the development of AVs, is the selection and cultivation of species adapted to the micrometeorological conditions generated by AV. This study reports on physiological, morphological and yield data of a soybean crop grown under AV. In addition, field data were compared with results from a simulation carried out with the modelling platform developed by Amaducci et al., 2018. Morphological and physiological and yield response of tomato and potato under Agrivoltaico® system parameters influenced by growth under AV were height, LAI and SLA, which were higher under AV than in normal “full light” (FL) conditions. Number of pods per plant decreased by 13% under AV compared to FL conditions while mean grain yield was reduced by 8%, only in one AV area was observed a slightly increase (+4.4%) in grain yield. The results on RMSE revealed that the model error was higher in two AV conditions compared to the other 3 treatments.

Agrivoltaics (AV) combines photovoltaic (PV) electricity generation with agriculture on the same land. In Chile, despite high potential, AV is not yet commercialized due to high investment cost. To close the remaining cost gap to conventional PV, we shed light on a set of AV specific synergies in the market segment of Small Distributed Generation Facilities. Through a techno-economic model, this paper monetizes AV synergies to derive the economic performance of a sun tracked AV system over blueberries for the PV stakeholder. The study reveals that tracked AV systems can be operated with an Internal Rate of Return (IRR) of 5.2% at the threshold of profitability. This is enabled due to the exploitation of synergies within the market segment that improve IRR for the PV stakeholder by 2.5%. Still, sun-tracked AV requires compulsory technology grants between 5 – 10 USD/MWh to be economically implemented. The results indicate the necessity for regulative adaption. Legislation must open agricultural land for AV project development to enable the commercialization.

Agricultural Photovoltaic (APV) has become more popular worldwide. Its core idea is to generate electricity and grow crops simultaneously on the same farmland. We developed two APV, Spectrum Splitting and Concentrated APV (SCAPV) and Even-lighting Agricultural Photovoltaic (EAPV). Our previous studies have investigated electricity generation, enhanced growth of plants/crops, and reduced water evaporation simultaneously on the same farmland. Furthermore, SCAPV and EAPV examined the better quality and increased yield of many plants, such as lettuce and cucumber. However, the effects of SCAPV and EAPV on sweet potato quality and yield have not been studied. Therefore, this study aims to investigate the impact of SCAPV and EAPV on evapotranspiration (ET) and sweet potato quality and yield. We conducted three treatments: SCAPV, EAPV, and open-air (CK). We planted 32 m2 of sweet potatoes and placed a weather station in each treatment. Our results showed that the 32 m2 of sweet potato yield under SCAPV, EAPV, and CK were 121.53 kg, 99.55 kg, and 77.84 kg, respectively. The dry rate in CK was 11.75% lower than 13.41% and 13.81% under SCAPV and EAPV, respectively. Soluble sugar content increased under EAPV. Anthocyanin content under SCAPV improved. Therefore, SCAPV and EAPV positively affect dry matter accumulation and enhance the sweet potato's growth. Average ET under SCAPV and EAPV compared with CK significantly reduced by 31% and 23%. SCAPV and EAPV could reduce irrigation and provide feasible green energy and sustainable APV solutions.

A comprehensive and supportive legal framework is a key factor for the expansion of agrivoltaics. This study analyzed, therefore, the existing laws, regulations, and policies related to agrivoltaics in Japan and assessed its actual effects on relevant stakeholders. An increasing horizontal policy integration on the federal level was identified. However, the vertical policy integration is still insufficient with often skeptical municipalities and local agricultural councils. The key barriers are related to the land-use conversion process, financing of agrivoltaic projects, socio-political and market acceptance, and grid constraints in rural areas. There are, however, opportunities for addressing these challenges in recently established councils that include a variety of members from industry, academia, and government.

Public perception of Agri-PV cannot be reliably assessed at this time, in part because the agricultural context and appearance of each Agri-PV system varies widely. Therefore, within the research project "Agri-PV Fruit Growing", a social impact analysis of Agri-PV in a fruit growing region (predominantly apple growing) was carried out in May 2021 and interviews with local social representatives with public functions (multi-stakeholder approach) were conducted. The goal of the survey, which took place in parallel to the implementation of a pilot Agri-PV plant, was to get detailed insights to acceptance factors among the relevant stakeholder groups. As well, the implications regarding communication and informal participation in future Agri-PV plants will be elaborated.

The present study examined the performance of the 100 kWp agri-voltaic systems at ICAR-CAZRI, Jodhpur. The average PV generation from the 100 kWp AVS connected to the grid via a bi-directional energy meter or net meter was about 342 kWh day-1. The average yields of mung bean, moth bean, and cluster bean in the inter-row spaces between the modules in the two-row and three-row PV array were 1155, 670, and 2008 kg.ha-1, respectively. Thus, there were 4.6%, 8.6%, and 11.8% reductions in the yield of mung bean, moth bean, and cluster bean, respectively, in inter-row spaces between the panels compared to control. During Rabi (irrigated) 2021-22, the yield of chickpea, cumin, and isabgol (2490, 1000, and 700 kg ha-1, respectively) in interspaces of the AVS was lower than that of the control (2670, 1120, and 760 kg ha-1, respectively). AVS resulted in a yield reduction of 6.6, 10.3, and 7.8% in chickpea, cumin, and isabgol, respectively, compared to the control. The AVS shows the maximum IRR (20.38%), while PV-GM shows the lowest (19.42%) at the prevailing bank loan interest rate of 12%. The PBP estimated 7.47 years for AVS with irrigated crops and 8.11 years for AVS with rainfed crops, while it was 8.61 years for PV-GM. The lower value of the discounted PBP, the faster the repayment of the investment cost. Therefore, the highest LCOE (INR 3.45 kWh-1) is estimated based on the break-even electricity tariff in PV-GM, and the lowest LCOE is calculated in AVS (INR 3.17 kWh-1).

Thus, there were 4.6%, 8.6%, and 11.8% reductions in the yield of mung bean, moth bean, and cluster bean, respectively, in inter-row spaces between the panels compared to control. During Rabi (irrigated) 2021-22, the yield of chickpea, cumin, and isabgol (2490, 1000, and 700 kg ha-1, respectively) in interspaces of the AVS was lower than that of the control (2670, 1120, and 760 kg ha-1, respectively). AVS resulted in a yield reduction of 6.6, 10.3, and 7.8% in chickpea, cumin, and isabgol, respectively, compared to the control. The AVS shows the maximum IRR (20.38%), while PV-GM shows the lowest (19.42%) at the prevailing bank loan interest rate of 12%. The PBP estimated 7.47 years for AVS with irrigated crops and 8.11 years for AVS with rainfed crops, while it was 8.61 years for PV-GM. The lower value of the discounted PBP, the faster the repayment of the investment cost. Therefore, the highest LCOE (INR 3.45 kWh-1) is estimated based on the break-even electricity tariff in PV-GM, and the lowest LCOE is calculated in AVS (INR 3.17 kWh-1).","PeriodicalId":517222,"journal":{"name":"AgriVoltaics Conference Proceedings","volume":"422 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139895829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
