The purpose of this guide is to help Michigan communities meet the challenge of becoming solar- ready by addressing SES within their planning policies and zoning regulations. This document illustrates how various scales and configurations of photovoltaic SES fit into landscape patterns ranging between rural, suburban, and urban. This guide will aid in community development and guidance related to public policy decisions related to solar energy development, which often includes agrivoltaic operations and development as well.
This study includes discussion on key benefits, tensions, and paradigms influencing farmers and farming communities’ decisions to host utility-scale solar generation. The first goal of this study is to develop a conceptual map of stakeholder interaction(s) around utility-scale solar deployment on agricultural lands. The second goal includes the critique of agrivoltaic solutions that fail to consider stakeholder priorities as technological fixes.
Scientists and engineers have recommended agrivoltaics to solve conflicts between land use for energy versus agriculture. The study discusses and focuses on stakeholder perceptions and paradigms about using agricultural land, particularly prime farmland. The study covers the question of how does the existing context of energy and agricultural systems affect solar siting, and how are stakeholders interacting to coproduce decisions?
The results of this study provide a conceptual map of stakeholder interaction on solar development on agricultural lands and argues that agrivoltaics are currently treated as a “technological fix.”
This report discusses the synthesis of four new symmetrical UV-absorbing diimides organic dyes for potential cosensitization process in greenhouse-integrated dye-sensitized solar cells (DSCs). Molecular cosensitization is favorable for manipulating solar radiation through the judicious choice of cosensitizers having complementary absorption spectra. For greenhouse-integrated dye-sensitized solar cells (DSCs), the manipulation of solar radiation is crucial in order to maximize the flow of photosynthetically active radiation (PAR) for the effectual photosynthetic activity of plants; meanwhile, non-PAR is utilized in agrivoltaics for generating electricity.
This report discusses the effects of solar radiation and total system head on techno-economics of a PV groundwater pumping irrigation system designed for sustainable agricultural production. The materials and methods of the study include crop water requirements, estimated pumping rates, estimations of PV-array ratings and solar charge controllers, and economic estimations of PV-pumping system(s). The results of the study also include an environmental impact analysis.
The study shows that installing a Photovoltaic Water Pumping System (PVWP) system represents the best technical and economic solution to drive a water pump that provides water for sprinkler irrigation. This application could be applied in AgriSolar operations that include sprinklers and agricultural land.

This research presents a highly transparent concentrator photovoltaic system with solar spectral splitting for dual land use applications. The system includes a freeform lens array and a planar waveguide. Sunlight is first concentrated by the lens array and then reaches a flat waveguide. The dichroic mirror with coated prisms is located at each focused area at the bottom of a planar waveguide to split the sunlight spectrum into two spectral bands. The red and blue light, in which photosynthesis occurs at its maximum, passes through the dichroic mirror and is used for agriculture. The remaining spectrums are reflected at the dichroic mirror with coated prisms and collected by the long solar cell attached at one end of the planar waveguide by total internal reflection. Meanwhile, most of the diffused sunlight is transmitted through the system to the ground for agriculture. The system was designed using the commercial optic simulation software LightTools™ (Synopsys Inc., Mountain View, CA, USA). The results show that the proposed system with 200× concentration can achieve optical efficiency above 82.1% for the transmission of blue and red light, 94.5% for diffused sunlight, which is used for agricultural, and 81.5% optical efficiency for planar waveguides used for power generation. This system is suitable for both high Direct Normal Irradiance (DNI) and low DNI areas to provide light for agriculture and electricity generation at the same time on the same land with high efficiency.
In this paper, the researchers applied the InVEST modeling framework to investigate the potential response of four ecosystem services (carbon storage, pollinator supply, sediment retention, and water retention) to native grassland habitat restoration at 30 solar facilities across the Midwest United States.
Colloidal quantum dots (QDs) are nanometer-sized semiconductor crystals grown via low-cost solution processing routes for a wide array of applications encompassing photovoltaics, light-emitting diodes (LEDs), electronics, photodetectors, photocatalysis, lasers, drug delivery, and agriculture. A comprehensive technoeconomic cost analysis of perovskite quantum dot optoelectronics is reported. Using economies-of-scale considerations based on price data from prominent materials suppliers, we have highlighted that increased QD synthesis yield, solvent recycling, and synthesis automation are critical to market adoption of this technology and driving quantum dot film fabrication costs down from >$50/m^2 to ∼$2−3/m^2
Decomposition models of solar irradiance estimate the magnitude of diffuse horizontal irradiance from global horizontal irradiance. These two radiation components are well-known to be essential for the prediction of solar photovoltaic systems performance. In open-field agrivoltaic systems, that is the dual use of land for both agricultural activities and solar power conversion, cultivated crops receive an unequal amount of direct, diffuse and reflected photosynthetically active radiation (PAR) depending on the area they are growing due to the non-homogenously shadings caused by the solar panels installed (above the crops or vertically mounted). It is known that PAR is more efficient for canopy photosynthesis under conditions of diffuse PAR than direct PAR per unit of total PAR. For this reason, it is fundamental to estimate the diffuse PAR component in agrivoltaic systems studies to properly predict the crop yield.
