Solar Thermal at ARC (Completed)

Project History

  • 10/19/2020

    The meter tracking production of the solar thermal panels on the ARC stopped working.  When investigated, we found that the controller was replaced a while back and the incorrect program was loaded.

    "Why doesn't the company installing the solar panels at U of I put them over the parking lot? I would provide shade for the cars underneath and would eliminate having to kill whatever would be underneath them in the fields."


The 24-panel, gravity fed solar-thermal system on the roof of the ARC preheats domestic cold water prior to its introduction into the steam-powered heat exchanger for domestic hot water, which significantly reduces steam usage for domestic hot water during normal operating periods. There are three main areas of hot water usage (domestic, pool, and air heating), but domestic (i.e. showers and sinks) represents the most pressing need and efficient use of solar technology.
