The project

Hoot Lake Solar is Otter Tail Power Company’s first utility-scale solar project and Minnesota’s third-largest solar generation facility. Its 130,000 solar panels produce enough renewable energy for roughly 9,000 homes. It sits on the site of a retired power plant, which let it connect to existing transmission lines.

The system

Premier Energy USA and Otter Electric installed ThermaRay thermal mass floor heating in the site’s 50 × 100 foot operations and maintenance building. 119 panels at 277 volts were laid out before the sand and concrete were placed over them.
