USS-4400 Solar Thermal Panel

We achieve the high efficiency of our system by more than quadrupling the solar surface (compared to the closest comparative panel). In addition, we do this without losing conductivity from the aluminum solar element to the copper tube, which is the transport for the for the solar heated liquid.

In order to quadruple the solar surface, the panel has been designed with serpentine tubing for fluid transport. The tubing is oriented horizontally in the panel, engineered to fit a total of fifteen tubes, each with 200 fins, or 50 fins per linear foot. In total, the USS-4400 48”x48” panel contains 60 feet of tubing, and approximately 9000 in.² of thermal element area, providing exceptional surface area for thermal absorption.

Our serpentine design allows for increased residence time (the time that the fluid is available for heat gain) of the fluid, which gives increased efficiency of the conductivity from tube to liquid, thereby increasing the overall efficiency of the panel. In fabrication, all panel tubing assembly is done without brazing the connections to minimize manufacturing costs.
