OSTI ID:5192051

Martin Marietta's design, fabrication and installation of an active cooling system for their 2.2 kW pedestal mounted Fresnel lens photovoltaic array is described. The previous design used a finned extruded aluminum passive heat exchanger to keep the solar cells cool. The actively cooled rectangular extruded aluminum channel through which coolant flows and cools the cells. The channel is attached at its center to the tracking structure and it supports two 1 ft. by 4 ft. modules (as with the passive design). The channels for side-by-side module pairs are connected by cast headers and flexible hoses. Coolant flows from module pair to module pair in a serpentine path through the array.
