Here are the main points from the article:

1. New Agrivoltaic Model: Spanish researchers have developed a new model to accurately estimate oil and energy production in agrivoltaic facilities set up in hedgerow olive groves.

2. Innovative Approach: The proposed model integrates mathematical equations to assess the impact of system design variables, allowing for simulations of solar radiation absorption by crops.

3. Benefits of Hedgerow Olive Groves: Compared to traditional olive groves, hedgerow designs facilitate high levels of mechanization and lower costs, with added advantages such as easier pest control and irrigation.

4. Simulation Insights: The researchers found that oil production per unit length is maximized when tree rows are spaced farther apart, although wider spacing reduces the overall number of olive trees per hectare.

5. Publication and Future Research: The findings are published in the "Cleaner Production Journal," and researchers from Córdoba University have developed additional methods for optimizing land use for agriculture beneath dual-axis solar trackers.

Researchers in Spain have developed a new model to accurately estimate oil and energy production from agrivoltaic systems in hedgerow olive groves. This approach allows for the generation of mathematical equations to predict the impact of system design variables.

The team from the University of Córdoba has created a model to simulate solar radiation in agrivoltaic installations in hedgerow olive orchards. Compared to traditional olive groves, hedgerow designs offer higher mechanization levels and lower costs. These groves cover significant areas in Spain and Portugal—100,000 hectares and 120,000 hectares, respectively—and are emerging as a common design for new groves, particularly in production areas away from the Mediterranean. They provide benefits like higher plant density, easier pest and disease control, and simplified irrigation and reproduction.

Lead researcher Marta Vero Martinez stated, “Our tool integrates a model to simulate radiation all the way from the sun to the crops, including the absorption of radiation through the crop canopy.” This model can estimate both electricity and oil production.

The proposed model considers the interaction between solar radiation, solar modules, and crop growth in south-facing agrivoltaic setups using horizontal trackers. In this system configuration, both oil and energy production can be alternately integrated with hedgerow olive groves in between solar panels.

The model takes into account global solar radiation and Photosynthetically Active Radiation (PAR), including direct and diffuse components. The research team noted, “Once the incident radiation on the crop is determined, it’s crucial to estimate the radiation transmission within the olive canopy,” assuming that the crop hedgerow is divided into adjacent parallel quadrants.

The model was applied in a south-facing intensive olive farm in Córdoba, Southern Spain, with varying row spacing. The PV system was based on astronomical tracking and non-backtracking trackers. The researchers explained, “The height of the rotation axis ranges from 2.5 to 3.5 meters in 0.5-meter increments, and the width of the modules ranges from 2 to 4 meters in 1-meter increments,” leading to the generation of 81 different geometric combinations.

Simulations allowed for the determination of PAR distribution absorbed within each primary parallel quadrant, revealing that the highest oil production per unit length of hedgerow can be achieved with greater spacing between tree rows, which allows for more solar radiation to reach the crops. However, using wider spacing reduces the overall number of hedgerows per hectare, consequently lowering oil production per unit area.

The proposed approach can accurately estimate the effects of shading caused by solar panels on annual oil and electricity production. It also enables the generation of mathematical equations to predict the impact of design variables. Vero Martinez added, “These equations reflect the data trends for finding the best usage with the smallest tested inter-row distances.”

Their findings are published in the article, “Simulation Model for the Electrical and Agricultural Productivity of Olive Hedgerow Agrivoltaic Systems,” in the Cleaner Production Journal.

Another research team from the University of Córdoba has recently developed a new method to calculate how much land can be used for agricultural purposes under photovoltaic plants based on dual-axis solar trackers.
