U-Pipe, or Direct Flow Evacuated Tubes have several significant advantages over other popular evacuated tube models. First, they are smaller – their lower footprint allows for an increased number of collectors in a smaller area. Additionally, direct flow evacuated tube collectors can be installed directly vertical (for instance, on the side of building) or completely flat against a flat roof.
