The unveiling and ribbon cutting of Solar Double Cropping took place at Piedmont Biofuels Eco-Industrial Park on November 4, 2011.

A project that had been two years in the planning, is demonstrating local food AND renewable energy in one big experiment! We are proud to offer tours of this forward thinking idea.
Miraverse Power and Light of Manifold RecordingPiedmont BiofuelsSouthern Energy Management, Piedmont Biofarm and Abundance are pleased to announce the ground breaking of their “Solar Double Cropping” project in Pittsboro, North Carolina.

The endeavor consists of an elevated 92.16 kilowatt solar array that is generating electricity above the north field of Piedmont Biofarm, while sustainable produce is harvested at the ground level. The nine-foot clearance of the solar photovoltaic system is designed specifically to encourage growing crops that thrive in partial shade.

“Double Cropping is a term we borrowed from the wind industry,” said Lyle Estill, co-founder of Piedmont Biofuels, and originator of the project.  “We intend to demonstrate the ability to make electricity and grow food in the same space at the same time.”
Estill noted that in some jurisdictions, solar installations are being banned on prime farmland.  “We need clean energy.  And we need sustainable food,” Estill said.  “This installation will enable both.”
Financing for the project has been provided by Michael and Amy Tiemann, who recently opened Manifold Recording, a world-class recording and production facility in Chatham County.  “The vision for this facility has always been based around sustainability.  When we began calculating the energy required to run this facility, we simultaneously envisioned how we could fit that into an overall sustainability plan.  Of all the options we considered, solar double-cropping was far and away the simplest, fastest, and best approach to meeting our energy needs without diminishing the rich agricultural potential of Chatham County.  What good is sustainable energy without sustainable agriculture?” said Tiemann.
Michael Tiemann also sits of the Board of Advisors for the Center for Environmental Farming Systems and has a keen interest in both renewable energy and local food.  He created Miraverse Power and Light as an entity for this endeavor.
Doug Jones, the owner of Piedmont Biofarm, has been experimenting with partial shade crops for the past two growing seasons and will be farming beneath the array.  “As our agricultural zone changes, there are some vegetables that will benefit from some protection from the sun,” Jones said.
The 288-panel system is being installed by Southern Energy Management (SEM), a Morrisville-based company well known for utility scale solar arrays.  “We love this project because it challenges us to think about land use, climate change and where our food comes from, all at the same time,” said SEM co-founder Maria Kingery.  “This is the kind of project that made us want to get into the solar business in the first place and we hope to see many more projects like this in the future.”
This Solar Double Cropping project represents two years of planning, design, and engineering which resulted in a formal docket assignment by the North Carolina Utilities Commission.
