SunTrac Solar’s SmartPanel is a concentrating solar thermal panel with a computerized sun-tracking control system to adjust the concentrators, eliminating stagnation of the heat transfer fluid and degradation of the panel caused by excess heat. To control exit temperatures of the heat transfer fluid, SunTrac adds its RiteTemp temperature-sensing system to the SmartPanel. RiteTemp monitors the temperature of heat transfer fluid as it leaves the panel, allowing the system to tune the mirrors and keep fluid temperatures and pressures in an optimum range.
