Add as preferred source Photovoltaic technology, most commonly seen as bulky solar panels used on solar farms, is expected to become a dominant energy source by 2050. But these panels are often installed on land that might otherwise be used to grow crops and feed a burgeoning population.
Agrivoltaics aims to solve this problem by planting crops around or underneath rows of solar panels, allowing for more efficient land use. In previous studies, solar panels were shown to help shade and protect certain crops and increase soil moisture, suggesting that carefully designed systems could support both agriculture and clean energy production.
Existing agrivoltaic research, however, tends to focus on one aspect of this process at a time—for example, light availability or crop growth—rather than addressing the nuanced interactions among microclimates, crop type, light and panel type .
A study published in Journal of Advances in Modeling Earth Systems shares a new model that can simulate the microclimates beneath solar panels and addresses the heat stress workers might face in actual conditions.
The new model simulates interactions among solar panels, crops, soil, air and water movement, and carbon dioxide uptake by tracking how energy, momentum and mass move through the agrivoltaic system. The researchers used agrivoltaic site data, including leaf temperature measurements taken in Davis, Calif., and soil temperatures taken in Chicago City, Minn., to assess how the model's predictions matched real-world conditions.
They then applied the model to a hypothetical agrivoltaic tomato farm using weather data from a hot, humid day in Princeton, N.J., a representative location for the densely populated Mid-Atlantic region, where food and energy are both in high demand.
Compared with tomatoes grown in an open field, tomatoes grown under solar panels experienced leaf temperatures that were 1.84°C cooler during the day overall and up to 7.56°C cooler during peak afternoon heat, reducing water loss through evapotranspiration by 22.4%.
Even though the simulated crops received 47% less sunlight, their carbon uptake declined by only 31%, suggesting that more temperate conditions lowered heat stress and partially offset the effects of increased shade.
The solar panels themselves were also 5.6°C cooler during the daytime than panels in bare soil, allowing them to recover about 15% of the efficiency lost during hotter temperatures. The average perceived temperature for humans decreased by 4.46°C during working hours, implying important occupational health and safety benefits for farmworkers.
The researchers suggest that the model can be used to examine the benefits of agrivoltaic farms and other climate and crop combinations.
