NOLS Southwest has just completed the installation of a 64-panel solar array. The 19.7-kW system, which was installed by local Tucson company, Technicians For Sustainability, sits atop the ranch house and in-town offices. While the project does not dethrone the Noble for the title of largest solar array at NOLS, it will supply between 70 and 80 percent of the branch’s energy demands annually, approximately 37,000 kWh.
