Agrivoltaic systems create numerous synergies between the aspects of agriculture, climate protection, climate change adaptation, land use and energy. For this reason, the present study examined the environmental impact of this technology using the life cycle assessment approach. Three scenarios were developed: An APV scenario with combined production of electricity and potatoes on one field (scenario 1), a PV scenario with separate production of PV electricity and potatoes (scenario 2) and a scenario in which electricity production is covered by the German electricity mix (scenario 3). All three scenarios showed the same output in energy production (500.13 kWp) and in potato production (307.87 dt/a or 9,236 dt/30 years). The results show that APV systems have similar impacts as open-space PV systems and achieve significantly better performances than the German electricity mix. In half of the impact categories examined, the environmental impacts were caused by potato production, in the other half by electricity production. Due to current developments in system design and solar module development, it can be expected that the life cycle impact of APV systems will continue to improve in the future.

Open-air poultry farming is currently developing with the increasing society demand for livestock farming better considering animal welfare. Outside animal comfort and open-air runs exploration could be enhanced by shelters such as trees or photovoltaic (PV) trackers. The aim of this study is to evaluate (i) the microclimates generated under PV trackers, (ii) the effect on laying hens comfort, (iii) the use of panels shadow area by hens. In three experimental sites, microclimates were studied and laying hens were counted in a control area, under a PV tracker and under a tree. Results showed that PV trackers, as trees, lowered summer soil and air temperatures and radiation, decreased the occurrences of stress situations for hens, and that more hens were counted under trackers than in a control area. Methodological improvements can be led to better apprehend differences of area uses by hens.

Bifacial vertical panels have been successful in agrivoltaics since the beginning of this system expansion worldwide. While the question of irradiation reduction effect on evapotranspiration has been largely addressed during last years, the question of wind modification and its impact on evapotranspiration has not been the object of a thorough attention yet. Wind modification is expected to be of greater importance in vertical agrivoltaics, panels acting like windbreaks. This preliminary research aims to assess the potential reduction of evapotranspiration in different climates and to highlight the importance of going further on aerodynamics and water demand topics. It shows that non negligeable amounts of water could be saved if those wind abatement rates are created by the rows of vertical panels compared with the evapotranspiration reduction expected induced by the irradiation reduction. Actually, modification in wind direction and speed will depend on geometrical parameters and wind direction. More measurement campaigns and comprehensive models of aerodynamics (CDF) and evapotranspiration are required to assess the relevance of vertical panels to tackle aridity in constrained climates.

Agrivoltaics (AV) represents a valuable alternative to solve the conflict between the expansion of renewable energy and land consumption in the course of the energy transition. Although the Austrian Renewable Energy Expansion Act (EAG) and accompanying regulations contain some provisions on the eligibility of AV under the national support scheme for renewable energy, the other areas of law affected by AV have not yet been adapted accordingly. In particular, there is a lack of appropriate zoning types in the spatial planning acts of the Länder that could promote multiple uses of land for AV. This results in an unsatisfactory legal framework that poses numerous legal problems for the implementation of AV in Austria. To ensure the long-term implementation of AV, the Austrian legal framework must therefore be adapted accordingly, especially with regard to the creation of suitable zoning types, which take into account various aspects, such as energy production, domestic agricultural production, landscape integration and social acceptance. In the course of this process, questions of competence between the federal government and the Länder will play a decisive role.
在能源转型过程中，农业光伏（AV）是解决可再生能源扩张与土地消耗之间矛盾的一个重要选择。尽管《奥地利可再生能源扩展法》（EAG）及配套法规中包含了一些关于农用光伏发电是否符合国家可再生能源支持计划的规定，但受农用光伏发电影响的其他法律领域尚未做出相应调整。特别是，各州的空间规划法案中缺乏适当的分区类型，无法促进反车辆土地的多种用途。这导致法律框架不能令人满意，给奥地利反车辆地雷的实施带来了许多法律问题。因此，为了确保 AV 的长期实施，必须对奥地利的法律框架进行相应的调整，特别是在创建合适的分区类型方面，要考虑到能源生产、国内农业生产、景观整合和社会接受度等各个方面。在这一过程中，联邦政府与各州之间的权限问题将起到决定性作用。

The projected increase in demand for food, water, and energy owing to systemic shocks has heightened the need for innovative solutions and integrated resource governance. The Agrovoltaics for Mali and Gambia (APV MaGa) Project, focuses on sustainable electricity production through agrovoltaics' triple land-use system and is leveraged with digital technologies. The project addresses The Gambia’s high food importation gap, growing dependency on fossil fuels for electricity generation, and high electricity tariffs. However, the nascence of agrovoltaics presents a new energy dimension that calls for increased coordination of sectoral policy and management, a domain of WEF nexus governance detached mainly from governance practice. Thus, a policy and institutional foresight of the potential implications of agrovoltaics’ integration is warranted, since Gambia’s decision-making for land, water, energy, and agriculture remains mainly sectoral. A qualitative research design was adopted, using a sample of twenty-eight key informative interviews, policy document analysis, and grey literature. Research findings show that the existing policy frameworks such as ‘Feed-in tariffs for excess RE, renewable energy funds, and capital subsidies can practically accommodate the frame of the agrovoltaics. However, clarification is required on the siting aspect of solar panels within the compartmentalized land policy structures. Institutionally, the Ministry of Energy’s nexus platform allows for technical coordination of agrovoltaics projects. However weak institutional harmonization, technical/financial incapacities, and overriding national interests due to sectoral bias present challenges. Therefore, harmonizing sectoral divergent policy provisions, interests, and prioritization of sustainability concerns will foster the pertinent integration of agrovoltaics for fast expansion.

In Italy, agrivoltaic systems (APVs) are seen as a driver for getting the national targets for photovoltaics (PV) and decarbonization, to enhance innovation in the agricultural sector, and reducing the energy costs on farms, overcoming land and landscape preservation issues, which cause bottlenecks in the permitting process of PV in agricultural areas. On April 2021, ENEA, in collaboration with ETA Florence Renewable Energies, launched the first Italian Network for Sustainable Agrivoltaics, with the objective of building knowledge and good practices around APV, enabling to support the implementation of sustainable agrivoltaic solutions and to build up a shared vision of Sustainable Agrivoltaics including three dimensions: Energy, Agriculture and Landscape. In the framework of the activities of the Italian Network for Sustainable Agrivoltaics, ENEA elaborated a communication strategy in cooperation with ETA Florence Renewable Energies, tailored to the identified major target groups (scientific community, broad public, specific stakeholder/user groups, farmer associations, media) and appropriate communication channels and conceived key communication elements. With the publication of the Guidelines for The Design, Construction and Operation of Agrivoltaic Plants on 27 June [1], new topics open up for the future which mainly concern the design and quality assessment around APVs in which the Network can be involved, thus maintaining a role of promoting knowledge advancement in this sector.
在意大利，农业光伏系统（APVs）被视为实现国家光伏（PV）和去碳化目标的驱动力，以加强农业部门的创新，降低农场的能源成本，克服土地和景观保护问题，这些问题在农业地区的光伏许可过程中造成了瓶颈。2021 年 4 月，ENEA 与 ETA Florence Renewable Energies 合作，启动了首个意大利可持续农业光伏网络，其目标是积累有关农业光伏的知识和良好实践，支持可持续农业光伏解决方案的实施，并建立包括三个方面的可持续农业光伏的共同愿景：能源、农业和景观。在意大利可持续农业光伏网络的活动框架内，ENEA 与 ETA 佛罗伦萨可再生能源机构合作，针对确定的主要目标群体（科学界、广大公众、特定利益相关者/用户群体、农民协会、媒体）和适当的传播渠道，制定了一项传播战略，并构想了关键的传播要素。随着 6 月 27 日《农业光伏电站的设计、建设和运行指南》的出版[1]，未来将出现新的主题，主要涉及农业光伏电站的设计和质量评估，该网络可参与其中，从而继续在该领域发挥促进知识进步的作用。

The impact of shading on selected ornamental plant species was investigated by monitoring plant growth under a nontransparent roof in a nursery in Jülich and in an AgriPV-System in Rathenow. Plants were continuously measured using different RGB camera systems. Shading led to an increase in projected leaf area, increased petiole length and specific leaf area. Morphological changes in shade-sensitive Geranium cinereum plants led to a loss of plant marketability. Flowering time of Hydrangea sp. was not affected in a long term experiment in the AgriPV-System. Pigment composition was not altered significantly in Rhododendron plants. Experiments will be continued with a local nursery in a novel AgriPV-System established near Jülich.

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.

We present a new Agri-Horti-PV system installed at the end of 2021 in the brown coal area of North Rhine-Westphalia near Jülich, Germany. The system contains different PV installations: Standard south oriented PV modules with a rainwater harvesting set up and east-west tracker modules, of which one is equipped with a rainwater harvesting setup. For the investigation of plant growth under the PV panels and on the reference areas without PV installations a novel rail system allowing for automatic camera movement is integrated in the Agri-Horti-PV park. Using the camera setup plant growth measurements with high spatio-temporal resolution will be possible. The scientific investigations of crop growth and the influence of variable shading conditions controlled by the tracking system started in the growth season of 2022. Here we present the technical details of the system as well as first results of an experiment carried out with faba beans, assessing impact of the Horti-PV system on growth dynamics and leaf morphology.

In 2020, the AgriVoltaics conference was “launched” and the small community, working to develop innovative solutions to combine agricultural production and PV energy, met for the first time. It was great and surprising to see that this community was actually not so small; it was spread over all five continents, and united by the belief that agrivoltaics is perfectly suited to a sustainable energy transition. We all know that there is no one solution to suit all, and that we have a long road ahead to further understand and improve agrivoltaic systems. It is in this time, when sustainable solution are urgently needed, that our community must collaborate to accelerate the availability of sound agrivoltaic systems. Exchange of information and experiences was at the core of Agrivoltaics2021, where the importance of “connecting” agrivoltaics worldwide was highlighted, and despite it being held online it was a great success! The growth of agrivoltaics is exponential, as indicated by the ever-increasing number of scientific publications on the topic, by the number of new agrivoltaic systems installed and last but not least, by the interest that large energy players and governments have paid to agrivoltaics. Our community now has a great opportunity, but also a responsibility to develop and bring forward true agrivoltaic systems where the production of PV electricity is necessarily coupled to agricultural production. While we work to optimise AV systems, we must also make sure that the policies supporting their implementation will prevent agrivoltaic projects from being abandoned, and becoming nothing more than ground mounted PV systems. This should be our concern when “bringing agrivoltaics forward”. Bringing agrivoltaics forward was therefore the theme and focus of AgriVoltaics2022 Conference, and with 488 participants from 46 countries (and more than half on-site) it was a great success. The program embraced a broad spectrum of topics ranging from policy making, economics and social acceptance to technical and scientific aspects related to the modelling and validation of crop production under agrivoltaics and technological advances in agrivoltaic systems. The need for a sustainable integration of agrivoltaics systems into the landscape was also addressed in many presentations. In addition, a Sustainable Agrivoltaic Integration Challenge was organised and a Student Award was granted. These proceedings provide a comprehensive overview of all the topics presented at AgriVoltaics2022 and are a testimony to the growing contribution that the international scientific community is making to bring agrivoltaics forward.

It was great and surprising to see that this community was actually not so small; it was spread over all five continents, and united by the belief that agrivoltaics is perfectly suited to a sustainable energy transition. We all know that there is no one solution to suit all, and that we have a long road ahead to further understand and improve agrivoltaic systems. It is in this time, when sustainable solution are urgently needed, that our community must collaborate to accelerate the availability of sound agrivoltaic systems.
