Solar Sharing for Both Food and Clean Energy Production: Performance of Agrivoltaic Systems for Corn, A Typical Shade-Intolerant Crop

This article concerns research conducted at a 100-m2 experimental farm with three sub-configurations: no modules (control), low module density, and high module density. In each configuration, 9 stalks/m2 were planted 0.5 m apart. The biomass of corn stover grown in the low-density configuration was larger than that of the control configuration by 4.9%. Also, the corn yield per square meter of the low-density configuration was larger than that of the control by 5.6%.

Solar Photovoltaic Architecture and Agronomic Management in Agrivoltaic System: A Review

This article reviews factors that influence solar PV and agronomic management in agrisolar systems. The authors conclude that several adjustments for crop selection and management are needed due to light limitation, microclimate condition beneath the solar structure, and solar structure constraints. The authors also conclude that a systematic irrigation system is required to prevent damage to the solar panel structure.

Semi-Transparent Organic Photovoltaics Applied as Greenhouse Shade for Spring and Summer Tomato Production in Arid Climate

This study investigates the effects of semi-transparent, wavelength-selective OPV solar on a greenhouse tomato crop in the arid southwestern U.S. This study demonstrates that the use of semi-transparent OPVs as a seasonal shade element for greenhouse production in a high-light region is feasible. However, a higher transmission of PAR and greater OPV device efficiency and durability could make OPV shades more economically viable, providing a desirable solution for co-located greenhouse crop production and renewable energy generation in hot and high-light intensity regions.

Agrivoltaics Provide Mutual Benefits Across the Food-Energy-Water Nexus in Drylands

This study investigates a hybrid of co-located agriculture and solar photovoltaic (PV) infrastructure by monitoring micro-climatic conditions, PV panel temperature, soil moisture and irrigation water use, plant eco-physiological function and plant biomass production within a agrivoltaic ecosystem and in traditional PV installations and agricultural settings to quantify trade-offs. Authors find that shading by the PV panels provides multiple additive and synergistic benefits, including reduced plant drought stress, greater food production and reduced PV panel heat stress.
