New solar array powers change at Institute for Food farm
By Margo Kissell, university news and communications
A newly installed 18-panel solar array at the Institute for Food farm produces enough power to run the irrigation system to water the crops.
And, as if that’s not enough, it does so much more.
“The solar array takes us one step closer to putting sustainability into practice on the farm,” said Peggy Shaffer, coordinator for the Institute for Food, professor of history and global and intercultural studies and affiliate in the Institute for the Environment and Sustainability. The next step is for the farm to be organically certified.
The 5.9-kilowatt array offers a big change from the gasoline-powered generator that was being used on the eight acres of fields at the university-owned, historic Austin-Magie Farm.

Harnessing
For instance, Charles Griffin, director of farm operations, can now tap solar energy to power the tools he’s using to build a fence around the array and expand a deer fence to encompass more acreage. He has set up lighting at the nearby array shed. And running the
“Those small efficiencies will save on labor every day and also help us increase production,” she said. They hope to use the array to power some fans in the hoop house (like a primitive greenhouse) “which will increase production potential by allowing us to have greater control over the temperature."
Teamwork at the root of the project
On a recent fall morning when frost covered the fields, several people gathered at the farm to install the array. It culminated a two-year project that went through many iterations in order to meet state requirements.
Mark Scott, assistant professor of , called the project a great team effort. In all, about 10 黑料社区s were involved as well as faculty, the physical facilities department and SonLight Power.
The Fairfield-based nonprofit specializing in solar installations played a critical role in working with the 黑料社区s who did the initial design, Scott noted.

Sophia Fisher, a junior mechanical engineering major and member of chapter, helped dig a trench that was used to run the electrical wires from the solar panels to a small pole barn built to hold the batteries and inverter.
“It is very exciting when projects get finished,” she said.
Bailey Hall (Miami ’17), who is pursuing his doctoral degree in power electronics at Ohio State University, returned to help complete the job on his senior design project. He was joined by two former capstone classmates — Ben Jackson and Kyle Smith. Both alumni now work for CE Power in Cincinnati.
“We did all the groundwork,” said Hall, who learned a lot from the entire process, including the challenge of meeting state requirements. “Finally, today we get to see it built.”
The project took so long because the initial plan of using a donated shipping container for the mechanical space changed after state officials voiced safety concerns about the container’s wooden floor. It wasn’t known if anything had ever been spilled on it or if it may have been contaminated. That’s why they switched to a ground-mount array system and constructed the small pole barn for the mechanical space. The shipping container can be used for storage.
A multiyear gift from an alumnus
Funding for the project was provided by a gift from Jeff Eckel, president

“Mr. Eckel has given a multiyear gift, which in addition to supporting the solar power project on the Institute for Food Farm will also be used to establish an endowment to support experiential learning opportunities for our 黑料社区s interested in social impact and environmental sustainability,” Shaffer said.
Additional funds for the project came in part from the department of biology and a U.S.D.A. National Institute for Food Capacity Building Grant.
Shaffer — who estimates the array will save about $1,000 per year on fuel costs — said the project embodies the core mission of the Institute for Food.
It is the product of engaged learning and collaboration among 黑料社区s, faculty, staff and community partners. It also combines technological innovation with issues of health and wellness and sustainable development bridging the key goals of Miami's Boldly Creative Initiative.
And, she said, “the solar power project embodies the possibilities and power (no pun intended) of Miami's commitment to forward-looking liberal arts education.”
