Another energy that can be utilized from the photovoltaic panel is heat due to solar radiation. To optimize the delivery of heat from the surface of the solar panel, the pipe must be made to have the broadest contact area. To create this, the pipe must be flattened by a special tool or machine. The flattened pipe cannot be leaked. Incorrect method of pipe flattening will cause cracks in areas with high strength. Other demands, the results of the flattened pipe must be straight. To expel air in the pipe, one end of the pipe is tightly closed by the brazing method and the other end is given a one-way valve for the vacuum pump line. For permanent closure, the tip with the one-way valve is closed by the pressing method, then the remaining pipe is cut. Author’s hypothesis, a machine with a gradual roll mechanism is precisely used to get a good flat pipe. Closing the last tip pipe end by pressing and cutting method. The results of this method are satisfactory, the flattened pipes are straight, the welding and compression do not cause leakage. This paper will be discussed the design of the rolling and pressing mechanism, followed by the analysis of the force, moment, and torque of the pipe formation. Then it will also analyze the appropriate motor drive power requirements
