MSU researchers develop solar technology for efficient irrigation

By Andi Anderson

Michigan State University (MSU) researchers are working to make irrigation systems more energy-efficient using solar-powered technology. Supported by a $394,600 USDA grant, the project aims to address energy challenges faced by farmers while promoting renewable energy solutions.

Led by Younsuk Dong, an assistant professor in MSU’s Department of Biosystems and Agricultural Engineering, the three-year initiative focuses on integrating solar-powered microinverters with irrigation systems.

These devices optimize energy usage, helping farmers manage rising electricity demands on Michigan farms, where irrigation accounts for most on-farm energy consumption.

Dong emphasized the dual issues of limited electrical grid capacity and the growing demand for sustainable energy. “We aim to make motors more efficient and reduce grid stress, ensuring sustainable agricultural operations,” he said.

The project builds upon Dong’s earlier work with the Low-Cost Monitoring System (LOCOMOS), which uses sensors to provide real-time irrigation recommendations. This new initiative combines these sensors with solar-powered systems to enhance both water and energy efficiency.

Field trials will take place at MSU research farms and partner sites in Michigan and Indiana. The team, which includes Purdue University researcher Woongkul (Matt) Lee, will evaluate the system’s potential to lower energy costs while maintaining effective irrigation practices over the next three years.

Agricultural irrigation accounts for over 40% of U.S. water use, according to the U.S. Geological Survey. This project highlights the importance of balancing productivity with resource conservation. “This technology offers significant energy savings and could become a cost-effective option for farmers with available tax incentives,” Lee noted.

The project also includes an outreach program to share findings through webinars, conferences, and direct farmer engagement, encouraging widespread adoption of solar-powered irrigation systems. With these innovations, MSU researchers aim to create sustainable farming solutions that support energy and water conservation.
