This report discusses the goal of agrisolar systems, which would generate electricity from raised solar panels and allow crop cultivation under the solar panels, and their development. Details of the report include the effect of raised solar panels and their effect on shading, which affects factors of the crops development. This information can be used to potentially optimize the design of agrisolar operations to most effectively benefit the crops included in the agrisolar operation.

This study examines a variety of percentages of the total area covered with shade produced by photovoltaic modules on rooftop lettuce crops. The results of the study suggest that in areas of high radiation and temperature(s), it is possible to use the same area on rooftops to produce photovoltaic energy and effectively cultivate plant species that demand little sunlight, such as lettuce. These conclusions mean that rooftop agrisolar is effective when the strategies in this study are taken into consideration.
Implications for vegetation growth when large opaque objects such as solar collectors are placed between the sun and ground-level vegetation across large portions of earth surface have received little attention to date. The present study seeks to address this void, advancing the state of knowledge of how constructed PV arrays affect ground-level environments, and to what degree plant cover, having acceptable characteristics within engineering constraints, can be re-established and thrive.
Eden Renewables, a New York solar developer, is taking action to support local agriculture by developing eight new pollinator-friendly solar farms in Schodack, Schaghticoke, Glen, and Claverack. Construction is expected to be completed around July 2022.
The solar farms will be a huge benefit to pollinators. More than 35 million native grasses and wildflowers, all pollinator-friendly, will be used as ground cover for each 35-acre site. This amounts to a total of 280 acres being used for biodiversity and ecological enhancement, according to a Eden Renewables press release.
“Eden’s community solar farms are a great example of how land can be used for multiple purposes – generating clean power, providing wildlife habitats, pollinator services, and producing food with sheep grazing and beehives making honey. Soon there should be butterflies fluttering, birds singing and bees buzzing around newly planted photovoltaic panels, helping local people to save money on their energy bills,” said Giovanni Maruca, Eden’s Chief Development Officer, according to Eden Renewables.
Each of the solar farms will generate 7.5 MW, enough energy to power around 1,225 homes. In total, the eight farms will generate 60 MW of clean energy, powering some 9,800 households.
Eden Renewables develops solar energy and storage projects in the United States, the UK, Africa, with a focus on continuing agricultural use, biodiversity, ecological enhancement, and community and educational benefits.

Agrisolar is a rapidly expanding sector with incredible potential. It brings together two major sectors of our society and economy: agriculture and energy. The goal of this guide is to draw on past experiences, to take stock of “what works” and “what doesn’t,” in order to advise local and international actors on successfully developing Agrisolar. This first edition of the SolarPower Europe Agrisolar Best Practices Guidelines takes a step in joining forces with agricultural stakeholders to better understand how the solar and agricultural sector can work more closely together, enhancing synergies to advance the energy and climate transition. Every Agrisolar project is unique as it must be adapted to the local agronomical, environmental, and socioeconomic conditions of the project site, and adapted to the needs of farmers and other relevant stakeholders. The most important element to ensure that Agrisolar projects perform effectively as agricultural and photovoltaic projects is to begin by clearly defining a Sustainable Agriculture Concept. Defining a Sustainable Agriculture Concept means assessing how to improve the sustainability of the agricultural practices carried out on site, assessing whether the project can provide local ecosystem services, assessing how it can be best integrated within the local social and economic setting, all while generating clean electricity. Following best practices throughout all 19 areas identified in these guidelines will ensure Agrisolar projects deliver tangible benefits, as planned in the Sustainable Agriculture Concept.
This study aims to analyze a PV power plant type rainwater harvesting system (PVPPRWHS) in a 600 kW grid-connected solar photovoltaic (PV) power plant. An experimental rainwater harvest was carried out in only 128 m2 of the Altınoluk Solar Power Plant, which has a surface area of 4320 m2. This study showed that the potential for collecting rainwater from a small part of the PV plant is approximately 118 m3 per year and that the harvesting system will reach 1646 m3/year when applied to the whole plant. The harvested rainwater is used for panel cleaning and agriculture to combat climate change and drought.
Evaluating the albedo impact on bifacial PV systems based on case studies in Denver, USA and Västerås, Sweden. This study aims to develop a simulation and optimization tool for bifacial photovoltaic (PV) modules based on the open-source code OptiCE and evaluate dynamic and static albedo impact on a bifacial PV system. Further, a review of the market price development of bifacial PVs’ and an optimization to maximize energy output was conducted.
Agrivoltaic systems, consisting of the combination of photovoltaic panels (PVPs) with crops on the same land, recently emerged as an opportunity to resolve the competition for land use between food and energy production. Such systems have proved efficient when using stationary PVPs at half their usual density. Dynamic agrivoltaic systems improved the concept by using orientable PVPs derived from solar trackers. They offer the possibility to intercept the variable part of solar radiation, as well as new means to increase land productivity. The matter was analysed in this work by comparing fixed and dynamic systems with two different orientation policies. Performances of the resulting agrivoltaic systems were studied for two varieties of lettuce over three different seasons.
This study examines the crop outputs for Swiss chard, kale, pepper, and broccoli in an AV system with different gap spacings of 2, 3, 4, or 5 feet (AV plots) between panel clusters within rows to determine how much spacing between solar panels is optimal for crop production by comparing these system yields to full sun crop production. This study also examines the effect of the AV system on crop nutrient levels, on soil water content, and crop leaf temperature below the panels.
Kale, chard, broccoli, peppers, tomatoes, and spinach were grown at various positions within partial shade of a solar photovoltaic array during the growing seasons from late March through August 2017 and 2018.
