Cornell University researchers reported on Apr. 14 that solar panels can provide wind protection for crops when used in agrivoltaic systems, according to PV Magazine. The study highlights an additional benefit of combining agriculture with solar energy production.
The findings are important for farmers considering agrivoltaics, as the technology could help safeguard crops from wind damage while also producing clean energy. This dual-use approach aims to optimize land use and support both agricultural yields and renewable energy generation.
Max Zhang, the study’s corresponding author, said to PV Magazine: “Airflow under solar panels is a key consideration for agrivoltaic systems. If conditions are too windy, crops can be damaged; if too calm, crops risk mildew.” The research team used computational fluid dynamics modeling to analyze how different panel configurations affect airflow around crops. By adjusting the tilt and position of single-axis sun-tracking panels, they found it was possible to block strong winds at low angles and allow beneficial airflow when tilted upward.
The scientists compared their designs with traditional agricultural windbreaks and worked to ensure that proposed solar installations would be compatible with existing farming practices. Their goal was to develop a system that supports robust crop growth while generating passive income from solar power and reducing reliance on fossil fuels.
Additional studies indicate that many types of crops thrive under the shade provided by solar panels, which can also offer relief for farmworkers and animals during extreme weather conditions. Wind protection is now seen as another promising advantage of agrivoltaics.
Zhang told PV: “The new lowered-first-row design offers an aerodynamic solution to the acceleration zone found in other agrivoltaic scenarios, achieving up to 86% protection in the shelter zone under extreme wind conditions.” Looking ahead, the research team plans further investigations into how real-time management of panel positioning could maximize benefits for farmers.
