SD-ECOModels Solar Design SD-ECOmodels exist in four different sizes (please download the technical datasheet for more info). For a better adaptability, four angles of frames are available (8°, 20°, 38°, and 45°) and can be installed on metal or tile roofs. SD-ECOmodels are equipped with 1500mm length vacuum tubes and 58mm diameter. This ideal size optimizes the ratio size/yield/strength of solar water heaters.
