A calorimetric solar receiver is described for measuring incident and absorbed solar radiation reflected from the heliostat field at the Department of Energy's 5 MW Solar Thermal Test Facility, Sandia Laboratories, Albuquerque, New Mexico. The receiver consists of nine 1-meter (3.28-ft) square panels in a 3-meter (9.84-ft) square array. Each panel is capable of absorbing 0.5 MW of power, but the total array is limited to 1 MW. Each panel is cooled by an ethylene glycol/water solution entering at 61/sup 0/C (142/sup 0/F) in a flow circuit parallel to the other panels. Each panel is instrumented with a turbine flowmeter, inlet and outlet coolant thermocouples, and nine heat flux gages with integral thermocouples on one third-meter grid spacings. Details of mechanical, electrical power, instrumentation, data acquisition, and structural designs are presented. Results from initial tests of concentrating up to 1 MW of thermal power on the receiver are presented.
