Since the development of Agrivoltaics with panels placed above the plants, a new system is tested with vertical mounted bifacial photovoltaic panels, of which we present the results of the first year of two experimental sites. Such installations bring a lower shading level on the plant compared to fixed tilt or single axis tracking systems and could potentially suit fields with crops having low demands of shading. However, unlike more standard PV systems, few studies have detailed the effects of such devices on field crops. In this first experimental year, bifacial vertically mounted PV system showed interesting results with a stable or even a slight increase in annual crop yields. Also, harvest quality indicators are maintained or present favorable evolution indicating a high potential of vertical PV systems for Agrivoltaics.

It has been assumed that crops cultivated in agrivoltaics (AV) systems can produce enough carbohydrates through the process of photosynthesis because they are expose to an excess of light. However, many studies have shown increases in specific leaf area (SLA) under shading that can be associated to reductions in the photosynthetic capacity of leaves. This study aimed to evaluate the impact of severe and fluctuating AV shading on apple leaf morphophysiological characteristics (SLA and photosynthesis). 10-year-old ’Golden Delicious’ apple trees grown in a dynamic AV system were monitored over three consecutive seasons (2019 to 2021) along with a control without panels. From February 2019 until July 2021, the photovoltaic modules rotated to maximise tree shading (15 hours of shading per day in summer). From July 2021 onwards, a lighter shading strategy was tested (5.8 hours of shading per day in summer). SLA at several dates was always higher for trees in the AV system (bigger individual leaf area but thinner leaves). SLA was not modified when light availability was increased late in the season. Light response curves indicated a lower saturation point for leaves grown in the AV system and a linear negative relationship was found between SLA and maximal photosynthetic capacity. To avoid leaf morphology modifications due to shade acclimatation, we propose to avoid severe shading during leaf development. We expect this study will provide a better understanding on how to modulate the light microclimate at specific times of the season in dynamic AV systems.

Spring frost is a risk for fruit tree production. In this study, a dynamic agrivoltaic system (AV) was tested as a solution to protect trees from frosts. The study was done in a nectarine AV in France in 2022 and 2023. The AV plot was paired with an adjacent control plot without panels. Air temperature nearby the trees was measured continuously with thermo-hygrometers each year. In 2022 and 2023 frost sensors to mimic organ temperature were also used. In 2023, bud temperatures were continuously measured during bloom. Frosts during bloom were observed in 2022 and 2023 but only the 2022 frost was associated with flower damage. Solar panels were positioned in horizontal position during the nights with frost. Night air temperature nearby the AV trees was warmer in comparison with control trees (increases between 0.27 and 0.47 °C). An increase between 0.25-1.29 °C was also observed for frost sensors and between 1.61-1.69 °C for the flower buds. Phenology was similar between control and AV trees. In 2002, 35% of control flowers were injured during frost while less than 10% were injured in the AV. We conclude that agrivoltaics can be used to protect flowers from frost.

This study investigates the performance of agrivoltaic systems employing bifacial photovoltaic modules. A comparison between yield in Sweden and Italy was carried out. Three agrivoltaic system designs were evaluated: vertical fixed, single-axis tracker, and dual-axis tracker. The results showed that the specific production varied between 1090 to 1440 kWh/kWp/yr in Sweden and 1584 to 2112 kWh/kWp/yr in Italy, where the lowest production was obtained with the vertical fixed agrivoltaic system while the highest production was obtained with the dual-axis tracking agrivoltaic system. The vertical fixed design had a higher electricity production during low solar elevation angles, while the single-axis and dual-axis tracking designs had significantly higher power production during mid-day. The electricity production gain using a dual-axis tracker design was mostly during mid-day, but the increase compared to the single-axis tracker was only 1-2%. The study concludes that low-height, fixed agrivoltaic systems without tracking are well-suited for high-latitude countries like Sweden, while elevated systems with tracker solutions are more suitable for locations like Italy. The findings suggest that the performance of agrivoltaic systems with bifacial photovoltaic modules is highly dependent on geographical location and the specific characteristics of the crops grown beneath them.

In recent years, with the popularization of environmental protection concepts and the continuous development of new energy technologies, agrivoltaics has attracted increasing attention and become an important direction of new agricultural development as a new type of agricultural planting method and new energy utilization method. This article classifies ground-based agrivoltaic schemes into three categories according to different management and distributions of solar radiation: intensity management, spectrum management, and time management. The article also details the performance of high-quality schemes proposed by our research team for these three categories. In addition, the article proposes four evaluation indicators for agrivoltaic schemes: land equivalent ratio (LER), return on investment (ROI), water-saving performance, and crop-friendliness, and calculates the performance of different schemes proposed by our research team based on these indicators. Finally, we recommend using these four dimensions to evaluate the performance of agrivoltaic schemes.

Dear colleagues, I warmly welcome you to the proceedings of the 4th AgriVoltaics World Conference [1] in Daegu, Korea. Our community's journey in the dynamic interplay between agriculture, renewable energy, and sustainability began in 2020 and has shown a remarkable growth and influence. The AgriVoltaics World Conference 2023 saw a remarkable submission of 130 abstracts from 28 countries, bringing together almost 350 delegates from Europe, Asia, the Middle East, North and South America, and Africa, both in-person and online. These proceedings present a diverse collection of scientific investigations, innovative advancements, and forward-thinking techniques, capturing the development of agrivoltaics from theory to a comprehensive resolution that tackles global issues. The concept of agricultural solar power generation, which was first introduced in 1981, has since been validated through empirical studies and regulatory frameworks established from 2013 onwards. As different countries adopt and adapt this concept, it is transforming into a powerful force for positive change, offering sustainable solutions tailored to unique circumstances. Korea, our host country, stands as evidence of the commitments made post the 2015 Paris Agreement. The country's efforts towards achieving carbon neutrality, along with proactive approaches such as population centralisation and rural communalisation, highlight the importance and practicality of our discussions. As we gather in Daegu, let us see this process not just as a repository of information, but as a source of inspiration. Together, let us envision and actively contribute to a future in which agrivoltaics provides practical solutions to address concerns related to climate change, food security, and environmental stewardship. I thank all of the conference participants, authors, presenters, reviewers, session chairs, my co-chair Prof. Jae Hak Jung, and the organizing committee for an extremely successful conference! Yours sincerely,Prof. Soo-Young OhChair of the Scientific CommitteeAgriVoltaics World Conference 2023

Solar panels affect the distribution of water and energy reaching the ground causing changes in soil moisture, evapotranspiration and percolation. In the context of Agri-Photovoltaics those changes influence plant growth and yield as well as irrigation demands while large Photovoltaic installations could potentially lead to changes in the water balance of the catchment. In either case, evapotranspiration plays an important role as the installation of panels of any design leads to shading thereby reducing the water loss to the soil through evapotranspiration. As it is difficult to measure evapotranspiration, the authors proceeded using soil moisture observations to quantify evapotranspiration pattern in dry periods. They found on average a 44 % higher evapotranspiration rate over 12 dry periods of varying conditions under the panels compared to a reference area at the research site Pillnitz. However, similar observations at the second site, Weesow show also a reversed behaviour due to reduced soil water availability as a result of the higher evapotranspiration at the reference area.

Water, energy, and food are essential for all humans and require land use. In a land-limited country with high ambitions for solar PV and a growing population, balancing land use for energy and food is necessary to avoid sectorial competition and minimise pressure on land resources. Agrivoltaics, an integrated approach combining energy and food production on the same land, can help to provide clean water, clean and affordable energy, and quality food for the growing population. This innovative approach to the water-energy-food-land nexus (WEFL) has been experimented with and attracted greater research interest and acceptance in many countries, mainly in the North but not so much in Africa. Agrivoltaics is relatively new in West Africa, and minimal research and development have been conducted within the region. As a desk-based study, this paper reviews the WEFL state in Benin and discusses how agrivoltaics could be an asset for current and future WEFL to improve sustainable development in Benin.

Installing photovoltaic (PV) collectors above arable land (Agrivoltaics) can aid with the shortage of available land area for solar power generation and food production. Most open field agrivoltaics are based on opaque PV devices which absorb photosynthetically active radiation (PAR, 400-700 nm), reducing crop yield and increasing variability in light distribution across the field. This research evaluates the performance of spectral beam splitter integrated photovoltaic (BSIPV) modules using a PV performance model. A high percentage (66 %) of PAR incident on the spectral beam splitter is transmitted effectively to the plants, while the near infrared radiation (NIR, > 700 nm) is reflected to the adjacent bifacial opaque photovoltaic module to generate power. In the model, seven rows of modules were placed uniformly across the field at a height of four meters from the ground. Considering a cool season (November – March) in Yuma, Arizona, in a conventional opaque PV agrivoltaic farm received 43 % lower total daylight integral (TDLI) across the season in comparison to open field with a coefficient of variation (ratio of standard deviation to mean expressed in percentage) of 56 % in TDLI across the field. On the other hand, the BSIPV agrivoltaic farm limited the drop in TDLI to 7 % in comparison to open field and the coefficient of variation to 14 % across the field. Thus, BSIPV showed a 36 % improvement in TDLI relative to the conventional opaque PV agrivoltaic farm. The results of the current study justify further research on the proposed collector concept.

The efficient and effective use of land that agriPV, or agrivoltaic, systems offer is especially appealing for Aotearoa-New Zealand, since more than a third of its land area serves agricultural purposes. However, several factors might constrain the implementation of agriPV systems, and different values and preferences need consideration from a community acceptance perspective. As a first step, a high-level investigation into the potential suitability of agriPV systems in Aotearoa–New Zealand was undertaken. The different factors that influence performance of agriPV systems were considered. Then a GIS analysis was undertaken using the analytical hierarchy process – a multicriteria decision-making technique. The spatial data analysis provided insight to identify the regions in Aotearoa–New Zealand best suited to agriPV systems. Overall, it is estimated that 80 percent of the farmland in the country is either good or fairly suitable for agriPV developments with a number of regions identified as potential areas for further investigations.

However, several factors might constrain the implementation of agriPV systems, and different values and preferences need consideration from a community acceptance perspective. As a first step, a high-level investigation into the potential suitability of agriPV systems in Aotearoa–New Zealand was undertaken. The different factors that influence performance of agriPV systems were considered. Then a GIS analysis was undertaken using the analytical hierarchy process – a multicriteria decision-making technique.
