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.

Solar siting is advancing rapidly in New York to meet the state’s climate goals of 70% renewable energy by 2030 and 100% clean energy by 2040, and much of that development is targeted towards farmland. However, with the right policies, incentives and research, solar development can avoid or minimize the most serious negative impacts on the availability and viability of New York’s best farmland and the strength of its agricultural economy and food security. Implementing the smart solar siting strategies recommended in this report can help farmers and agricultural communities capitalize on the benefits of solar development, explore new markets, participate in cutting-edge research partnerships, and continue growing the food we need now and in the future, all while combatting climate change.

This report describes a solar-powered pneumatic grain/seed cleaning system. The report stats that a solar powered pneumatic grain/seed cleaning system was developed with specific functional, structural and operational design parameters. The developed pneumatic cleaner was tested for garden pea, bottle gourd, sponge gourd and radish seed lots of different impurity levels. It was found that the processed lot achieved more than 99% physical purity irrespective of type of seed and impurity levels and the cleaning efficiency of the system was more than 96%.

This report describes the design and use of  a solar-powered fruit and vegetable grader. This study demonstrates one of the innovative, agricultural engineering features that can be potentially used in the context of various agrisolar operations that include crops.

This report describes a low-cost, solar-powered, air-inflated grain dryer. Moisture levels measured during harvest and storage can fluctuate based on the design and efficiency of grain dryers. These solar-powered grain dryers have been shown to be effective in optimizing the moisture levels during the harvest process. These innovative technologies can possibly be used in various contexts of agrisolar operations that include crops.

This report describes the design and construction of a solar photovoltaic food dryer. The hybrid solar-energy dryer uses PV panels to power the heating element coil and charging battery which includes a storage energy system used to study drying behavior. Solar-powered dryers could be effective technologies to use in future agrisolar operations that include grain or other crops.

This report describes the efficacy of a solar-powered cooler in Kenya. In addition to keeping the produce cooler, it also maintains the carbon dioxide and oxygen balance and reduces spoilage. These conclusions were drawn from variations of storage conditions and climate conditions of the beans in the study.

This NASA report describes a solar-powered refrigeration system that uses a variable speed, direct current (DC) vapor compression cooling system, connected to a solar photovoltaic panel. The system, patented by NASA, eliminates reliance on an electric grid, requires no batteries and stores thermal energy for efficient use when sunlight is absent. The system is specifically ideal for off-grid applications, and works well for vaccine coolers and solar-ice makers, among other things. Some of the contexts of this system’s application has been found in various agrisolar operations.

This report describes a food storage structure that includes a solar-powered, evaporative cooler. The storage structure was designed and developed to increase the shelf life of fresh fruits and vegetables. The report shows that this is made possible by solar-powered exhaust fans and a cooling pump that provides water to the pads. These applications may be useful when agrisolar operations are located in dry or desert conditions.
