Kansas scientists develop solar recharge system for farms

By Scout Nelson

Kansas Geological Survey (KGS) scientists have been awarded nearly $900,000 in grants to develop an innovative solar recharge system that uses underutilized corners of farm fields to generate energy and collect water. The project aims to support agriculture and renewable energy integration, providing economic, energy, and water conservation benefits.

The system will feature solar panels with rain collection gutters, directing rainwater into underground reserves to increase water availability for farmers. The panels will be installed in nonirrigated corners of fields where center-pivot irrigation systems do not reach.

“Our vision is that we can sidestep the growing competition for land between farms and renewable energy,” said Sam Zipper, assistant scientist at KGS and the project’s principal investigator.

The solar recharge system will address declining groundwater levels in Kansas aquifers, particularly in the west, where the project will be implemented. “If this project is successful, it could be an energy, water, and economic win-win-win for farms across the Midwest,” Zipper added.

Currently in the design phase, the goal is to have the system operational by the 2025 growing season. The project team is collaborating with farmers, local electrical utilities, and renewable energy companies to ensure the system meets utility regulations.

Field measurements, including soil water infiltration rates and historical groundwater data, are being gathered to fine-tune the project for the specific conditions of western Kansas.

“No successful project starts without first turning to the past to gather a better understanding of the future,” said project coordinator Hanna Szydlowski.

Funded by an $881,526 grant from the Foundation for Food and Agriculture Research’s Seeding Solutions program, the project is also supported by contributions from KGS, KU, Kansas State University, Michigan State University, and Wheatland Electric Cooperative. The initiative aims to set a precedent for sustainable agriculture and renewable energy solutions across the region.
